📘 Chapter 2: Oceans and Continents — Questions, Activities and Projects (Answers)

Question 1

The given Picture shows the symbol of the Olympic Games. What do these rings symbolise?

A. The five most popular sports   B. The five continents of the world   C. The five major oceans of the world   D. The five host countries of the Olympics

Answer: B. The five continents of the world

Question 2

Reason (R): Scientists study climate and environmental changes there.

A. Both A and R are true, and R is the correct explanation of A.
B. Both A and R are true, but R is not the correct explanation of A.
C. A is true, but R is false.
D. A is false, but R is true.

Answer: A. Both A and R are true, and R is the correct explanation of A.

Question 3

If most of earth's surface was covered by land instead of water, which of the following statement would likely be true?

A) Oceans would become larger   B) The earth would still look blue   C) There would be no change in appearance   D) The earth would appear brown from space

Answer: D. The earth would appear brown from space (because land, not water, would be the dominant colour seen from outer space).

Question 4 — Explain the following terms

(A) Continent: A large, continuous expanse of land is called a continent. Continents are surrounded by oceans but are too big to be called islands. Example: Asia, Africa.

(B) Ocean: The largest water bodies found on the globe are called oceans. They cover a little less than three-fourths of the Earth's surface. Example: Pacific Ocean, Indian Ocean.

(C) Island: A small piece of land surrounded by water on all sides is called an island. Islands are much smaller than continents. Example: Greenland, Lakshadweep Islands.

Question 5 — Evaluate the statement

"Oceans are often called the planet's lungs and climate regulators." Evaluate this statement.

Oceans are rightly called the planet's lungs because more than half of the world's oxygen is produced by tiny ocean plants called algae, just like our lungs give us oxygen. Oceans also act as climate regulators — they absorb heat from the sun and release it slowly, which keeps the Earth's temperature balanced. They are an important part of the water cycle too: the sun heats ocean water, it evaporates, forms clouds, and brings rain to the continents. Without this rain, our fields would dry up and there would be no food for us.

Protecting oceans is essential for the future of humanity because they give us oxygen to breathe, rain for our crops, food through fishing, and a home for countless plants and animals. If oceans get polluted by plastic waste and overfishing, marine life will die and the balance of nature will be disturbed, which will harm humans too. So, keeping our oceans clean and healthy is our collective responsibility for a safe future.

Question 6 — Awareness Message on Tsunami

⚠️ Stay Safe from Tsunami! ⚠️

Dear Friends,
A tsunami is a huge and powerful sea wave caused by an earthquake or volcanic eruption under the ocean. It can travel very fast and flood coastal areas suddenly.

How to stay safe:

• If you feel a strong earthquake near the coast, move to higher ground immediately.
• Never go near the beach to watch the waves, even if the sea suddenly pulls back.
• Listen to tsunami warning alerts on radio, TV, or mobile announcements.
• Keep a small emergency kit with water, torch, and first-aid ready.
• Follow instructions from the Disaster Management Authority and help others evacuate calmly.

Stay alert, stay informed, stay safe!

Question 7 — Let us do: Label the outline map

On the outline map of the world, label the continents and oceans as shown below:

Continents: North America, South America, Europe, Asia, Africa, Australia, Antarctica

Oceans: Pacific Ocean (appears on both left and right sides of the map), Atlantic Ocean, Indian Ocean, Arctic Ocean, Southern (Antarctic) Ocean

(Students should draw/label these names on their own outline map copy, using Fig. 2.3 in the chapter as a reference.)

Question 8 — Crossword Solution

No.	Direction	Clue	Answer
1	Across	Abundantly produced by the oceans	OXYGEN
2	Down	The largest island on Earth	GREENLAND
3	Across	A large expanse of landmass	CONTINENT
4	Down	A huge destructive wave from the ocean	TSUNAMI
5	Down	The smallest continent	AUSTRALIA
6	Across	A large continent of which India is a part	ASIA
7	Down	The largest body of water on the Earth	OCEAN
8	Across	A major source of pollution of the oceans	PLASTIC
9	Down	A landmass (but not a continent) surrounded by the sea or ocean	ISLAND
10	Across	The coldest continent	ANTARCTICA

Note: The exact grid arrangement of boxes may vary slightly with the printed crossword grid; the words above are the correct answers matching each numbered clue.

Question 9 — Let us draw

Without looking at the maps in the chapter, draw the seven continents (North America, South America, Europe, Asia, Africa, Australia, Antarctica) on a sheet of paper and colour each one differently. Afterwards, compare your drawing with the map of oceans and continents given in Fig. 2.3 of the chapter, and note down any differences you find in shape, size, or position.

(This is a hands-on drawing activity to be done individually by each student.)

🔎 In-text Activities — "Let's Explore" & "Think About It"

Let's Explore (Page 50)

1. What are the circular lines in each map called? And the lines radiating out from the poles?
Answer: The circular lines are called latitudes (parallels) and the lines radiating out from the poles are called longitudes (meridians).

2. Which hemisphere holds more water?
Answer: The Southern Hemisphere holds more water.

3. Approximate proportion of water to land in Northern and Southern Hemispheres?
Answer: The Northern Hemisphere has roughly equal parts water and land (slightly more water), while the Southern Hemisphere is mostly water, with only a small proportion of land.

4. Are all the oceans connected, or are there separations?
Answer: All the oceans are actually connected to one another; the divisions shown on maps are just conventions, not real boundaries.

Think About It (Page 50)

1. If there is so much water, why is there talk of 'water scarcity'?
Answer: Most of the Earth's water is salty seawater found in oceans, which cannot be used for drinking or farming. Only a very small portion is freshwater (found in glaciers, rivers, lakes and groundwater), and that limited freshwater is what people actually use — so there is scarcity of usable water.

2. Ways of saving water:
Answer: Turning off taps when not in use, fixing leaking pipes, using buckets instead of hoses, harvesting rainwater, reusing water for plants, and avoiding wastage during washing and bathing.

Let's Explore (Page 54) — Oceans and Hemispheres Table

Ocean	Northern Hemisphere	Southern Hemisphere
Pacific Ocean	✔	✔
Atlantic Ocean	✔	✔
Indian Ocean	—	✔
Southern Ocean	—	✔
Arctic Ocean	✔	—

Note: The Indian Ocean lies mostly in the Southern Hemisphere, with only a small part crossing into the Northern Hemisphere near India — hence it is mainly marked under Southern Hemisphere.

Let's Explore (Page 62) — Continents Diagram

1. Name the largest and smallest continent (by counting squares):
Answer: Asia is the largest continent, and Australia is the smallest continent.

2. Which is larger?
- North America or South America → North America
- Africa or North America → Africa
- Antarctica or Australia → Antarctica

3. Re-colour Europe and Asia as 'Eurasia' and compare with South America:
Answer: When combined, Eurasia is much larger than South America.

4. List of continents from smallest to largest:
Answer: Australia → Europe → Antarctica → South America → North America → Africa → Asia
