CHAPTER – 3 WATER BODIES (OCEANS AND SEAS )

HYDROSPHERE

The part of the earth surface occupied by water bodies is called the hydrosphere.

Oceans which occupy nearly two-third of the area of the earth are the major

components of the hydrosphere. Smaller water bodies such as lakes , rivers etc. are

the other components of the hydrosphere.

OCEAN

An Ocean is a large body of water on the earth surface surrounding a large

landmass. Oceans cover nearly 71 percent of earth’s surface. They contain almost 98 percent of all the water on earth.

There are five main oceans on Earth:-

The Pacific Ocean

The Atlantic Ocean

The Indian Ocean

The Arctic Ocean

The Southern Ocean.

THE PACIFIC OCEAN

The Pacific is the largest ocean that covers about one– third of the area of the earth.

It is the deepest ocean also. The Mariana Trench, the deepest ocean trench (11,022

metres deep), is also located within this ocean. The continents of North and South

America extend on one side of the Pacific ocean and Asia and Australia stretch on the

other side.

THE ATLANTIC OCEAN

The Atlantic Ocean, the second largest ocean, is situated between the North and South

America on one side and Europe and Africa on the other. There are many good

harbours on the coasts of this ocean because of its indented coastline. The Atlantic is

the busiest ocean of the world from the point of view of commerce and trade.

THE INDIAN OCEAN

The Indian Ocean is bounded by landmasses on three sides. Asia forms its northern

boundary while Africa stretches on the western side. Australia is situated on the

eastern side of this ocean. It is the only ocean of the world named after the name of a

country, India.

THE ARCTIC OCEAN

The Arctic Ocean lies within the Arctic Circle and the North Pole lies at the centre of

this ocean. It is the smallest ocean of the world. The Bering Strait, a narrow stretch of

water, connects the Arctic Ocean with the Pacific Ocean. Due to its location within the

polar circle, the Arctic Ocean remains covered with ice most of the year.

THE SOUTHERN OCEAN

The Southern Ocean is comprised of the most southern ocean water of the world

and is also referred to as the Antarctic Ocean, South Polar Ocean, and the Great

Southern Ocean.

OCEAN LIFE

Living things inhabit all levels of Earth’s Oceans. Ocean plants grow fairly close to the water’s surface because they need sunlight to stay alive. The most numerous ocean plants are called phytoplankton. These tiny, one –celled plants drift with the ocean

currents. The largest ocean animal is the blue whale. The tiniest animals are a form of

plankton called zooplankton.

IMPORTANCE OF THE OCEANS

The world’s oceans are important to life on earth. Oceans are great source of food for

people around the world. They also provide minerals, oil and natural gas. Ocean

currents have a direct impact on the climate of a place. Warm currents bring warm

weather and rain whereas cold currents tend to cause dry climate. People pollute ocean

by dumping poisonous waste and garbage into them. Over fishing and oil spills harm

ocean life as well.

EXERCISES

A) ANSWER THE FOLLOWING QUESTIONS IN BRIEF:-

Q1 - What is hydrosphere?

Q2 -Define Ocean.

Q3 - Name the major oceans of the world?

Q4 - Define phytoplankton.

Q5- Name the largest ocean animal.

B) ON THE OUTLINE MAP OF THE WORLD , MARK THE FOLLOWING :-

1. THE ATLANTIC OCEAN

2. THE PACIFIC OCEAN

3. THE INDIAN OCEAN

4. THE ARCTIC OCEAN

5. THE SOUTHERN OCEAN

1. The four river valley civilisations of the Bronze Age are –

i) Mesopotamian

ii) Babylonian

provided fairly accurate information about the seasons.

observed that the interval between two floods was 365 days and divided this

period into 12 months of 30 days each. The remaining five days were set aside for

festivals.

Class 6 Maths Worksheet-6

TOPIC- WHOLE NUMBERS

OPERATION OF DIVISION:-

Operation of division is an inverse operation of multiplication.

i.e. a ÷ b = c is same as b x c = a

example : 30÷5=6; 5x6=30

So, dividing 30 by 5 is same as finding a whole number which when multiplied by 5

gives 30.

Division Algorithm:-

Dividend= divisor x quotient + remainder

For above example:-

Dividend = Q x D + R

= 5 x 6 + 0

= 30 + 0

= 30

Properties of division of whole numbers :-

1. If a is any whole number, then a÷1 = a

Example: 40÷1=40

2. If a is any non-zero whole number, then a ÷ a = 1

Example: 240÷240=1

3. If a is any non-zero whole number, then 0÷a=0

Example: 0÷25=0

Division by 0 is not defined.

Illustrations:- The concept of Division algorithm is illustrated as follows:-

The first example explains how the answer of division can be checked through division

algorithm.

The second example illustrates how to find a greatest 4-digit number which is exactly

divisible by 135.

Q1 (a) Divide 7750 by 17 and check the result by division algorithm.

(b) Divide 6528 by 29 and check by division algorithm.

Q2(a) Find the largest 3-digit number which is exactly divisible by 47.

(b) Find the greatest 4-digit number which is exactly divisible by 357.

Q3 (a) Find the number which when divided by 38 gives the quotient 23 and remainder

17.

Sol Dividend = Q x D x R

= 23 x 38 + 17

= 874 + 17

= 891

(b) Find the number which when divided by 50 gives the quotient 93 and remainder 25.

(c) Find the number which when divided by 9 gives the quotient 47 and remainder 5.

Q4 State whether the following statements are true (T) or false (F):

a. If the product of two whole numbers is zero, then atleast one of them will be zero.

b. If the product of two whole numbers is 1, then each of them must be equal to 1.

c. If a and b are whole numbers such that a ǂ0 and b ǂ 0, then ab may be zero.

Q5. A vendor supplies 72 litres of milk to a student’s hostel in the morning and 28 litres of milk in the evening every day. If the milk costs 39 per litre, how much money is due

to the vendor per day?

Q6. Using shorter method, find:

a) 3246 + 9999

= 3246 + (10000-1)

=3246 + 10000-1

= 13246 - 1

= 13245

b) 5377 - 999

= 5377-(1000-1)

= 5377-1000+1

= 4377+1

= 4378

c) 123 x 999

= 123 x (1000-1)

= 123 x 1000 – 123 x 1

= 123000 - 123

= 122877

d) 7501+99999

e) 9825+9999

f) 25718-9999

g) 74815-999
