Types of Minerals

Metallic minerals contain metal in raw form. Metals are hard substances that conduct heat and electricity and have a characteristic lustre or shine. Iron ore, bauxite, manganese ore are some examples.

Metallic minerals may be ferrous or non-ferrous. Ferrous minerals like iron ore, manganese and chromites contain iron.

A non-ferrous mineral does not contain iron but may contain some other metal such as gold, silver, copper or lead.

Non-metallic minerals do not contain metals. Limestone, mica and gypsum are examples of such minerals. The mineral fuels like coal and petroleum are also non-metallic minerals.

The process of taking out minerals from rocks buried under the earth’s surface is called mining.

Minerals that lie at shallow depths are taken out by removing the surface layer; this is known as open-cast mining.

Deep bores, called shafts, have to be made to reach mineral deposits that lie at great depths. This is called shaft mining.

Petroleum and natural gas occur far below the earth’s surface. Deep wells are bored to take them out, this is called drilling

*Minerals that lie near the surface are simply dug out, by the process known as quarrying.

A green diamond is the rarest diamond.

ENVIRONMENT

◙Biotic components=Plants/Animals/Birds etc

◙Abiotic components=Land/Mountains/Rivers etc

◙The word environment is derived from french word "Environer" meaning "Neighborhood".

◙World environment day=5 June

◙Barter system =in which, goods are exchanged without the use of money

◙Ecosystem: It is a system formed by the interaction of all living organisms with each other and with the physical and chemical factors of the environment in which they live, all linked by transfer of energy and material.

INSIDE OUR EARTH

Layers of Earth

1.Crust

◙uppermost layer

◙Thinnest layer

◙35 km on continental masses and about 5 km on ocean floors

◙Main minerals of continental mass=silica and alumina. It is thus called SiAl.

◙Main mineral of oceanic crust= Silica and Magnesium. It is thus called SiMa.

2.Mantle

◙It extends upto depth of 2900 km.

3.Core

◙Radius =3500 km

◙Consists mainly Nickel and Iron. It is thus called NiFe.

◙The crust forms only 1 per cent of the volume of the earth.

◙84 per cent consists of the mantle.

◙15 per cent makes the core.

◙The radius of the earth is 6371 km.

ROCKS AND MINERALS

1.Igneous (Latin word Ignis meaning fire)

◙Also called primary rocks.
◙Intrusive ones cool slowly. E.g Granite
◙Extrusive ones are found in Deccan plateau. e.g Basalt

2.Sedimentary (Latin word sedimentum meaning settle down.)

e.g Sandstone
◙Red fort is made from Red Sandstone.

3.Metamorphic (Greek word metamorphose meaning change of form.)

◙Igneous and sedimentary rocks can change into metamorphic rocks under great heat and pressure. e.g clay changes into slate and limestone into marble.

Fossils: The remains of the dead plants and animals trapped in the layers of rocks are called fossils.

EARTHQUAKES

◙Similarly, when the Lithospheric plates move, the surface of the earth vibrates. The vibrations can travel all round the earth. These vibrations are called earthquakes.

◙The place in the crust where the movement starts is called the focus.

◙The place on the surface above the focus is called the epicentre.

◙Greatest damage is usually closest to the epicentre and the strength of the earthquake decreases away from the centre.

EARTHQUAKE WAVES

There are three types of earthquake waves:
1. P waves or longitudinal waves (PRIMARY)
2. S waves or transverse waves (SECONDARY)
3. L waves or surface waves (LOVE)
(*after A.E.H. Love, a British mathematician)

The other kind of surface wave is the Rayleigh wave,

◙Most of the shaking felt from an earthquake is due to the Rayleigh wave, which can be much larger than the other waves.

◙An earthquake is measured with a machine called a seismograph.

◙ The magnitude of the earthquake is measured on the Richter scale.

◙An earthquake of 2.0 or less can be felt only a little. An earthquake over 5.0 can cause damage from things falling. A 6.0 or higher magnitude is considered very strong and 7.0 is classified as a major earthquake.

◙There are thousands of small waterfalls in the world. The highest waterfall is Angel Falls of Venezuela in South America.

◙The other waterfalls are Niagara falls located on the border between Canada and USA in North America and Victoria Falls on the borders of Zambia and Zimbabwe in Africa.

MAJOR LAND FORMS

MEANDERS

As the river enters the plain it twists and turns forming large bends known as meanders.

In due course of time the meander loop cuts off from the river and forms a cut-off lake, also called an ox-bow lake.

LEVEES

At times the river overflows its banks. This leads to the flooding of the neighboring areas. As it floods, it deposits layers of fine soil and other material called sediments along its banks. This leads to the formation of a flat fertile floodplain. The raised banks are called levees.

DISTRIBUTARY

As the river approaches the sea, the speed of the flowing water decreases and the river begins to break up into a number of streams called distributaries.

DELTA

The river becomes so slow that it begins to deposit its load. Each distributary forms its own mouth. The collection of sediments from all the mouths forms a delta.

MUSHROOM ROCKS

◙An active agent of erosion and deposition in the deserts is wind. In deserts you can see rocks in the shape of a mushroom, commonly called mushroom rocks. Winds erode the lower section of the rock more than the upper part. Therefore, such rocks have narrower base and wider top.

SAND DUNES

◙When the wind blows, it lifts and transports sand from one place to another. When it stops blowing the sand falls and gets deposited in low hill – like structures. These are called sand dunes

LOESS

◙When the grains of sand are very fine and light, the wind can carry it over very long distances. When such sand is deposited in large areas, it is called loess. Large deposits of loess is found in China.

LOESS HIILS

COMPOSITION OF THE ATMOSPHERE

1.NITROGEN (78%)
2.OXYGEN (21%)
3.ARGON (0.93%)
4.CO2 (0.04%)

◙When we inhale, we take some amount of nitrogen into our lungs and exhale it. But plants need nitrogen for their survival. They can not take nitrogen directly from the air. Bacteria, that live in the soil and roots of some plants, take nitrogen from the air and change its form so that plants can use it.

STRUCTURE OF THE ATMOSPHERE

Troposphere: This layer is the most important layer of the atmosphere. Its average height is 13 km. The air we breathe exists here. Almost all the weather phenomena like rainfall, fog and hailstorm occur in this layer.

Stratosphere: Above the troposphere lies the stratosphere. It extends up to a height of 50 km. This layer is almost free from clouds and associated weather phenomenon, making conditions most ideal for flying aeroplanes. One important feature of stratosphere is that it contains a layer of ozone gas.

Mesosphere: This is the third layer of the atmosphere. It lies above the stratosphere. It extends up to the height of 80 km. Meteorites burn up in this layer on entering from the space.

Thermosphere: In thermosphere temperature rises very rapidly with increasing height. Ionosphere is a part of this layer. It extends between 80-400 km. This layer helps in radio transmission. In fact, radio waves transmitted from the earth are reflected back to the earth by this layer.

Exosphere: The upper most layer of the atmosphere is known as exosphere. This layer has very thin air. Light gases like helium and hydrogen float into the space from here.

◙Thermometer: Measures the temperature
◙Barometer: Measures atmospheric pressure
◙Rain Gauge: Measures the amount of rainfall
◙Wind Vane: Shows the direction of the wind

◙An important factor that influences the distribution of temperature is insolation. Insolation is the incoming solar energy intercepted by the earth. The amount of insolation decreases from the equator towards the poles.

◙A wind is named after the direction from which it blows, e.g. the wind blowing from the west is called westerly.

◙Winds can be broadly divided into three types.

1. Permanent winds – The trade winds, westerlies and easterlies are the permanent winds. These blow constantly throughout the year in a particular direction.

(The trade winds are so named because ships have historically taken advantage of them to aid their journies between Europe and the Americas.)

2. Seasonal winds – These winds change their direction in different seasons. For example monsoons in India.

3. Local winds – These blow only during a particular period of the day or year in a small area. For example, land and sea breeze. The hot and dry local wind of northern planes of India is called loo.

RAINFALL

On the basis of mechanism, there are three types of rainfall: 1.the convectional rainfall
2.the orographic rainfall
3.the cyclonic rainfall

DISTRIBUTION OF WATER BODIES

We all know that three-fourth of the earth surface is covered by water. If there is more water than land on this earth, why do so many countries face water scarcity?

◙Salinity is the amount of salt in grams present in 1000 grams of water. The average salinity of the oceans is 35 parts per thousand.

◙Dead sea in Israel has salinity of 340 grams per litre of water. Swimmers can float in it because the increased salt content makes it dense.

◙March 22 is celebrated as World Water Day

◙Tsunami is a Japanese word that means “Harbour waves” as the harbours get destroyed whenever there is tsunami

◙The tsunami of 2004 caused wide spread damage in the coastal areas of India. The Indira point in the Andaman and Nicobar islands got submerged after the tsunami.

TIDES

The rhythmic rise and fall of ocean water twice in a day is called a tide.

◙It is high tide when water covers much of the shore by rising to its highest level.

◙It is low tide when water falls to its lowest level and recedes from the shore.

https://www.youtube.com/watch?v=pwChk4S99i4

The strong gravitational pull exerted by the sun and the moon on the earth’s surface causes the tides. The water of the earth closer to the moon gets pulled under the influence of the moon’s gravitational force and causes high tide. During the full moon and new moon days, the sun, the moon and the earth are in the same line and the tides are highest. These tides are called spring tides. But when the moon is in its first and last quarter, the ocean waters get drawn in diagonally opposite directions by the gravitational pull of sun and moon resulting in low tides. These tides are called neap tides

OCEAN CURRENTS

1.WARM OCEAN CURRENTS
2.COLD OCEAN CURRENTS

◙Generally, the warm ocean currents originate near the equator and move towards the poles.

◙The cold currents carry water from polar or higher latitudes to tropical or lower latitudes.

◙ The Labrador Ocean current is cold current while the Gulf Stream is a warm current.

◙The ocean current influence the temperature conditions of the area. Warm currents bring about warm temperature over land surface.

◙The areas where the warm and cold currents meet provide the best fishing grounds of the world. Seas around Japan and the eastern coast of North America are such examples. The areas where a warm and cold current meet also experience foggy weather making it difficult for navigation.

Natural Vegetation and Wild Life

The two factors on which the growth of vegetation mostly depends are— temperature and moisture.

Natural vegetation is generally classified in to three broad categories as follows:

1.FORESTS

Which grow where temperature and rainfall are plentiful to support a tree cover

a) Tropical Evergreen Forests

These forests are also called tropical Rainforests.

◙These thick forests occur in the regions near the equator and close to the tropics. These regions are hot and receive heavy rainfall throughout the year. As there is no particular dry season, the trees do not shed their leaves altogether. This is the reason they are called evergreen.

◙The thick canopies of the closely spaced trees do not allow the sunlight to penetrate inside the forest even in the day time.

◙Hardwood trees like rosewood, ebony, mahogany are common here.

AMAZON RAINFOREST

◙The tropical evergreen forest in Brazil is so enormous that it is like the lungs of the earth

◙The Amazon River which runs through the Amazon rainforest is the world’s second longest river after the Nile. It is also the world’s largest by water volume.

◙The Amazon River System meanders through nine South America countries.

Brazil, Bolivia, Peru,

Ecuador, Colombia, Venezuela,

Guyana, Suriname and French Guiana.

b) Tropical Deciduous Forests

◙Trees shed their leaves in the dry season to conserve water.

◙The hardwood trees found in these forests are sal, teak, neem and shisham.

Hardwood trees are extremely useful for making furniture, transport and constructional materials. Tigers, lions, elephants, langoors and monkeys are the common animals of these regions.

c) Temperate Evergreen Forests

The temperate evergreen forests are located in the mid latitudinal coastal region. They are commonly found along the eastern margin of the continents, e.g., In south east USA, South China and in South East Brazil.

◙They comprise both hard and soft wood trees like oak, pine, eucalyptus, etc.

d) Temperate Deciduous Forests

As we go towards higher latitudes, there are more temperate deciduous forests . These are found in the north eastern part of USA, China, New Zealand, Chile and also found in the coastal regions of Western Europe.

◙They shed their leaves in the dry season.

The common trees are oak, ash, beech, etc. Deer, foxes, wolves are the animals commonly found.

Birds like pheasants, monals are also found here

e)Mediterranean Vegetation

◙Most of the east and north east margins of the continents are covered by temperate evergreen and deciduous trees. The west and south west margins of the continents are different. They have Mediterranean vegetation.

◙They have Clear skies and high temperatures; hot, dry summers and cool, wet winters.

◙It is mostly found in the areas around the Mediterranean sea in Europe, Africa and Asia, hence the name

◙This kind of vegetation is also found outside the actual Mediterranean region in California in the USA, south west Africa, south western South America and South west Australia.

◙There isn’t much wildlife here

https://www.pmfias.com/mediterranean-climate-warm-temperate-western-margin-climate-warm-temperate-west-coast-climate/#A_dry_warm_summer_with_off-shore_trades

◙Mediterranean trees adapt themselves to dry summers with the help of their thick barks and wax coated leaves which help them reduce transpiration.

◙Mediterranean regions are known as ‘Orchards of the world’ for their fruit cultivation.

f) Coniferous Forests

◙In the higher latitudes of Northern hemisphere the spectacular Coniferous forests are found . These are also called as Taiga. These forests are also seen in the higher altitudes.

Taiga means pure or untouched in the Russian language

TAIGA VEGETATION

◙The woods of these trees are very useful for making pulp, which is used for manufacturing paper and newsprint. Match boxes and packing boxes are also made from softwood.

◙Chir, pine, cedar are the important variety of trees in these forests.

◙Silver fox, mink, polar bear are the common animals found here.

2.GRASSLANDS

Which grow in the region of moderate rain.

a) Tropical grasslands:-

◙This vegetation grows in the areas of moderate to low amount of rainfall. The grass can grow very tall, about 3 to 4 metres in height.

Savannah grasslands of Africa are of this type.

Elephants, zebras, giraffes, deer, leopards are common in tropical grasslands

TROPICAL GRASSLANDS

b) Temperate grasslands:-

◙These are found in the mid-latitudinal zones and in the interior part of the continents.

◙Usually, grass here is short and nutritious.

◙Wild buffaloes, bisons, antilopes are common in the temperate region.

Grasslands are known by different names in different regions.

Tropical Grasslands
East Africa- Savanna.
Brazil- Campos
Venezuela- Llanos

Temperate Grasslands
Argentina- Pampas
N. America- Prairie
S. Africa- Veld
C. Asia- Steppe

Australia- Down

3.SHRUBS

◙Thorny shrurbs and scrubs grow in the dry region.

◙The vegetation cover is scarce here because of scanty rain and scorching heat.

TUNDRA VEGETATION

If you reach the polar region you will find the place extremely cold. The growth of natural vegetation is very limited here. Only mosses, lichens and very small shrubs are found here.

◙It grows during the very short summer. This is called Tundra type of vegetation.

TUNDRA VEGETATION

◙This vegetation is found in the polar areas of Europe, Asia and North America. The animals have thick fur and thick skin to protect themselves from the cold climatic conditions.

◙Seal, walruses, musk-oxen, Arctic owl, Polar bear and snow foxes are some of the animals found here

HUMAN SETTLEMENT
.
◙Transhumance: It is a seasonal movement of people. People who rear animals move in search of new pastures according to changes in seasons.

◙The Golden Quadrilateral connects Delhi, Mumbai, Chennai and Kolkata.

◙The Trans-Siberian Railway is the longest railway system connecting St. Petersburg in Western Russia to Vladivostok on the Pacific coast.

◙4 Means of transport are
a)Roadways
b)Railways
c)Waterways
d)Airways

LIFE IN THE AMAZON BASIN

The river Amazon flows from the mountains to the west and reaches the Atlantic Ocean to the east. The place where a river flows into another body of water is called the river’s mouth.

◙Numerous tributaries join the Amazon River to form the Amazon basin. The river basin drains portions of Brazil, parts of Peru, Bolivia, Ecuador, Columbia and a small part of Venezuela.

◙The Rainforest is rich in fauna. Birds such as toucans, humming birds are found.

toucan

◙Animals like monkeys, sloth and ant-eating tapirs are found here.

◙Various species of reptiles and snakes also thrive in these jungles. Crocodiles, snakes, pythons, Anaconda and boa constrictor are some of the species.

◙Several species of fishes including the flesh eating Piranha fish is also found in the river.

LIFE IN THE GANGA-BRAHMAPUTRA BASIN

◙The tributaries of rivers Ganga and Brahmaputra together form the Ganga-Brahmaputra basin in the Indian subcontinent.

◙The basin lies in the sub-tropical region that is situated between 10°N to 30°N latitudes. The tributaries of the River Ganga like the Ghaghra, the Son, the Chambal, the Gandak, the Kosi and the tributaries of Brahmaputra drain it.

◙In the Ganga and Brahmaputra plain tropical deciduous trees grow, along with teak, sal and peepal. Thick bamboo groves are common in the Brahmaputra plain.

◙Elephants, tigers, deer and monkeys are common. The one-horned rhinoceros is found in the Brahmaputra plain. In the delta area, Bengal tiger, crocodiles and alligator are found. Aquatic life abounds in the fresh river waters, the lakes and the Bay of Bengal Sea. The most popular varieties of the fish are the rohu, catla and hilsa. Fish and rice is the staple diet of the people living in the area.

◙In the fresh waters of River Ganga and River Brahmaputra, a variety of dolphin locally called Susu (also called blind dolphin) is found. The presence of Susu is an indication of the health of the river. The untreated industrial and urban wastes with high amount of chemicals are killing this species.

◙The Ganga-Brahmaputra plain has several big towns and cities. The cities of Allahabad, Kanpur, Varanasi, Lucknow, Patna and Kolkata all with the population of more than ten lakhs are located along the River

FATE OF PLUTO

Detailed Picture of Pluto

◙Pluto was classified as a dwarf planet (the largest dwarf planet) in 2006 by International Astronomical Union (IAU), for not fulfilling the requirements to be a planet as per the New definition.

◙As per the new definition, A body , in order to be classified as a planet, must satisfy 3 conditions.

1) It must orbit the sun.
2) It must have sufficiently large mass to bear a spherical shape.
3) It must have cleared the neighborhood around its orbit.

◙ The Pluto fulfilled first 3 conditions but not the 3rd one.

◙Eris is the most massive and second-largest known dwarf planet in the Solar System.

◙Presence of other celestial bodies like Make-Make, Haumea etc around the Pluto meant that the Pluto hasn't cleared the neighborhood around its orbit. So Pluto was demoted.

◙Pluto,Eris,Make-Make-Make and Haumea are some of important dwarf planets

MOON

◙Moon diameter is about one-quarter of the diameter of Earth.
◙Moon=384,400 km away from earth.

1/16=6.25%
1/17=5.88%

1/18=5.55%
1/19=5.26%
1/20=5%

Just learn these conversion of percentage into fraction, and youll be all set to learn quick and easy way to solve the questions based on percentage.

Example questions

1} 87.5% of 560

87.5% = 100% - 12.5%
=1-(1/8)= 7/8

So (7/8)*560=490

2} 55.55 % of 1260

55.55% = 5 x 11.11% =5/9

(5/9)*1260 =700

Similarly you can convert the percentage into fraction and then solve it.

3} 43.75%=50%-6.25%=(1/2)-(1/16)

4} 56.25%= 50% + 6.25%=(1/2)+(1/16)

5} 91.66% =75%+ 16.66=(3/4)+(1/6)

6} 25.26% =20% + 5.26%=(1/5)+(1/19)

7} 81.25% = 75% + 6.25%=(3/4)+(1/16)

8} 206.25% = 200%+6.25%=2+(1/16)

9} 91.66% = 75%+6.66%=(3/4)+(1/15)

10}63.63%= 7 x 9.09%=7/11

How to find a perfect square?

2019-06-10T13:19:00.001+05:30

HOW CAN YOU GET TO KNOW , WHICH NUMBER IS A PERFECT SQUARE?

You'll often find questions like these in the teacher eligibility test examinations.A lot of students puzzle over how to find a perfect square..And it is really easy to check which of the following number is a perfect square.

How to find a perfect square?

what is a perfect square?

any number which can be expressed as product of two integers is known as a perfect square.
e.g 25 can be expressed as 5x5, so it is a perfect square
100=10x10, so 100 is also a perfect square
but 80 can't be expressed like this, so it is not a perfect square.

How to check whether a number is a perfect square or not.?

1.All squares end up in 0,1,4,9,6,5

A perfect square never ends up in 2,3,7,8

So something like 15623 is not a perfect square , since it ends in 3...

And you don't have to cram it..Just check the unit digit of squares of numbers 0-9

0x0=0
1x1=1
2x2=4
3x3=9
4x4=6
5x5=5
6x6=6
7x7=9
8x8=4
9x9=1

So as you can see, a perfect square Never ends in 2,3,7,8.This should be the first thing you should check ,while inspecting a number.

2.THE DIGITAL SUM OF A PERFECT SQUARE IS 1,4,7,9

MNEMONIC(1947)

Digital sum is the sum we get after adding all the digits of a number until we get a single digit.

E.g 15626=1+5+6+2+6=2+0=2

Since it's digital sum is 2, it can't be a perfect square for sure..

KEEP IN MIND, THAT IF THE DIGITAL SUM OF A NUMBER IS 1,4,9,7, IT DOESN'T GUARANTEE THAT THE NUMBER IS A PERFECT SQUARE...

BUT IF THE DIGITAL SUM ISN'T 1,4,7,9, THEN THE NUMBERS CANT BE A PERFECT SQUARE FOR SURE..

SO IT IS AN ELIMINATION METHOD...

3.SOME OTHER THINGS TO CHECK

●If a number ends in 1, then tens digit is always even.

E.g 121, 961

●If a number ends in a 9, it's tens digit is always even

E.g 169,529

●If a number is ends in 5, then it's tens digit is always 2..

E.g 625, 5625

●If a number is even, then it's last two digits are divisible by 4

E.g. 64,144,196,8464

So if any of the above rules fail, then the number can't be a perfect square

E.g

34531(it ends in 1, and the ten's place isnt even, so it cant be a perfect square)

139(it ends in 9, and tens digit is odd, so it can't be a perfect square)

4575 (it ends in 5, and the tens digit is other than 2, so it is not a perfect square)

1214 ( it ends in 4, and last two digits are not divisor by 2, so it is not a perfect square)

Using these tricks , you can eliminate the numbers which are not perfect squares, and get to know the answer..

Question 1:-
Which of the following is a perfect square

A..548543213
B..548543215
C..548543251
D..548543241

◆digital sum of option a is 8, So it can't be a perfect square

◆Option b, ends in 5 and has an odd digit on tens place , so it can't be a perfect square

◆In option c , the number ends in 1 and the tens digit is odd, which is not possible in case of a perfect square

◆So our answer is option D

What the heck is this Number system?

2019-06-04T18:26:00.001+05:30

What is Number System and why it is important?

In this post, we will discuss what is number system and what are the various types of numbers in number system.

What is Number System?

A number system is a collection of various symbols, known as digits.

Different types of Number System

1. Binary Number System

A binary number system has a base of 2. It means thatin the binary number system, all the numbers can be represented by using 0 and 1.

The 2 symbols are 0 and 1

2. Decimal Number System:-

The number system which we follow is called as Decimal Number System where the base is 10.The base 10 indicates that there are 10 different symbols that we use.

0,1,2,3,4,5,6,7,8,9

These symbols are called as digits.

When we write a number in decimal system, the number on the extreme left is the most significant and the on the extreme right is the least significant..

In the decimal number system, The numbers have their place value according to their placement.

E.g in Number 3456

Place value of 3 = 3000

Place value of 4=400

Place value of 5=50

Place value of 6 is 6

And 3456 can be written as a sum of these numbers

3456=3000+400+50+6

Classification of Number System

A decimal number system has only 10 digits but using these 9 numbers , we can create infinite numbers.

You can't really think of a largest number..As a kid I always used to think that what is the largest possible number..

But there isn't any such number, as you can always add 1 to it and get even larger number.

The numbers thus formed can be divided into various categories depending on their nature..

●Real Numbers:

As a kid we studied about the number line. The number line has all the positive (including 0) and negative numbers.

7.8,-6.9,0,46.5,7/3,3.14

All these numbers are real numbers and they are not imaginary..

●Irrational numbers:-

The term rational comes from the word ratio..

The irrational numbers are those which can't be represented as a ratio..

E.g π
We usually consider π=22/7 but that's not an accurate representation.

22/7=3.142857142857142857...........
But π=3.141592653589793..............

We can see that 22/7 is only accurate up to 3.14, after which it is not accurate.

π is a never ending number, so we can never represent it in a form of a fraction .

Other examples of irrational numbers are
√2, √3
These are also never ending numbers , which we can't represent in the form of a ratio.

●Whole numbers:-

Have you ever tried counting the number of stars in the sky?●Whole number(complete)
Or
Have you ever counted the number of people ahead you in a queue?

If the answer to any of these questions is yes, then you're already familiar about the whole numbers.

The answer to any of these questions could be like 5,8,10,20,35,56 etc
These are numbers that represent whole things without pieces.They include all the positive numbers without fractions..

Of course there wouldn't be 76.43 stars , or 65/3 persons ahead you...hope you understood the concept of whole numbers..

-6,-7.9,3.14,5.6,1/2 These are not whole numbers.0,1,2,3,4,5,6,7,8 These all are whole numbers.

●Rational Number:

These are the numbers which can be represented in the form of m/n, where m and n are integers and n is not equal to 0. It could be recurring or non-recurring

2/3, 6/7, 3/4 ,-6.7,4.9,0.5,0.33

These are examples of rational numbers

-6.7 is a rational number since it can be written as -67/10

4.9 is a rational number, since it can be written as 49/10

0.5 is a rational number, since it can be written as 1/2

0.3333333.... can be written as 1/3

●Integers:-

INTEGERS ARE whole numbers (not a fractional number) that can be positive, negative, or zero.

Examples of integers are: -9, 231, 5, 8.3, 97, and 4.043.

Examples of numbers that are not integers are: -1.43, 9 3/4, 3.14, 0.08, and 5,123.1.

●Fractions: (m/n)

A fraction denotes a part or parts of a unit. It is majorly classified into following types-

◆Proper Fractions: In a proper fraction the numerator is always less than the denominator. Proper Fractions are always less than 1.
E.g 4/7, 8/10, 6/13

◆ Improper Fraction: In an improper fraction the numerator is more than the denominator. Improper Fractions are greater than 1.
E.g 8/3, 9/2, 78/23

◆ Mixed Fraction: A mixed fraction consists of two parts.
An integer part and a fractional part.
5 4/9, 3 4/11

●Natural Numbers:

It is the set of positive numbers.Types of Numbers –

The natural numbers are the numbers which we first learned as a kid.

1,2,3,4,5,6,7,8,9,10,11,12

Some mathematicians also include zero in the natural numbers, but most of them exclude zero.

Some other ways of classification

●Even Numbers: Set of numbers exactly divisible by 2.

e.g 2,4,6,56,42,238 etc

●Odd Numbers: Set of numbers not exactly divisible by 2.
e.g 1,3,5,7,9,57,49 etc

●Prime Numbers: Prime numbers are the numbers which have no factor other than 1 and itself.

●Composite Numbers: Composite numbers have factors other than 1 and itself.
E.g 320=2x2x2x2x2x2x5

so 320 is a composite number

This were the classification of the number system. If you liked the post, please share it and leave a comment below.It would really motivate me.

Paragraph (88-95)

Marie Curie was one of the most accomplished scientists in history. Together with her husband, Pierre, she discovered radium, an element widely used for treating cancer, and studied uranium and other radioactive substances. Pierre and Marie’s amicable collaboration later helped to unlock the secrets of the atom.

Marie was born in 1867 in Warsaw, Poland, where her father was a professor of physics. At an early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master’s degree and doctorate in physics.

Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heartbreaking anguish. Despondently she recalled their close relationship and the joy that they had shared in scientific research. The fact that she had two young daughters to raise by herself greatly increased her distress.
Curie’s feeling of desolation finally began to fade when she was asked to succeed her husband as a physics professor at the Sorbonne.

She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although Marie Curie eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work. Regardless of the consequences, she had dedicated herself to science and to revealing the mysteries of the physical world.

How to Improve vocabulary?

How to Improve vocabulary?

Improving vocabulary might seem to be a daunting task for you but it is rather interesting task..
The reason why a lot of people fail to improve their vocabulary is because they employ the wrong strategy..Mugging up some words daily isn't going to help you..

Mistakes that people do in learning vocabulary:-

1.Cramming some words and their meaning daily
The vocabulary of a language doesn't only have to do with the meaning of the words..You don't actually learn a new word Unless you know to use it in a context.

2.Not using efficient resources
there are tons of applications or books out there that might help you improve your vocabulary but most of those aren't very efficient.Any resource is only going to help you if it is according to your needs and your level..

If you're an advanced learner, having a book with basic words wont help you at all
similarly for a very beginner learner, an advanced book wont help at all

3.Not using that word

if you've learnt a word but you've never used that word in your daily routine, That word is useless...moreover you'll soon forget that word..

4.Not actually understanding the word (word root)
A word is not learnt completely until and unless you get to know the meaning of word root of that word..
word roots also help you guess the meaning of new words you've never come across

How not to do these mistakes?and how to actually improve your vocabulary?

1.Learn to use the words in a context

There are some words which have more than 2-3 meanings according to the context in which they are used in.

2.Use personalized resources
Here at Elucified you will get personalized vocabulary lessons..We have various categories like beginner and advanced...

so whatever your level of your vocab is, this blog is going to help you for sure.

3.Learning words and using those

Make an habit to learn some new words which you come across and learn to use those words in a proper context..

and then use those words in daily conversation with your friends..

4...Understand the evolution of the word
The words are very interesting..A lot of words have evolved a lot and have undergone a change in their meaning as well..

English language has taken a lot of words from other languages e.g Latin.

So learning about word root and how a word evolved over time , will help you guess the meaning of another word with a similar word root,

OTHER TIPS:-

1.Learn in a group

Instead of learning on your own , make a group of 3-4 friends because solo learning will get boring after some time..Learning something gets more interesting and beneficial if you learn in groups.

2.Learn some fancy words.
Now this is the most exciting part of vocabulary for me.I love to learn Awesome words.

e.g scrumptious=very tasty
lilliputian = very small

3.Follow shashi tharoor on twitter.

If by any chance, you don't know him...see some of his tweets below

He is author of many books as well..

4. Stay connected with this blog

because here we will provide you all the necessary resources that will help you improve your vocabulary.
