Oceans and Continents — NCERT Solutions

This is an activity-based question. Follow the steps below:

Step 1 – Recall the seven continents and their approximate shapes:

• Asia – largest continent, located in the eastern hemisphere; roughly triangular with irregular coastlines.
• Africa – second largest; roughly oval/rectangular shape.
• North America – triangular shape, wider at the top and narrowing towards the south.
• South America – roughly triangular, connected to North America.
• Antarctica – circular landmass at the South Pole.
• Europe – smaller landmass attached to Asia in the northwest.
• Australia – compact, oval-shaped continent in the southern hemisphere.

Step 2 – Draw freehand on paper:
Draw each continent in its approximate position on the globe — Asia and Europe in the centre-right, Africa below Europe, the Americas on the left, Australia in the bottom-right, and Antarctica at the bottom.

Step 3 – Colour each continent differently (e.g., Asia – yellow, Africa – orange, North America – green, South America – light green, Europe – pink, Australia – brown, Antarctica – white/light blue).

Step 4 – Compare your drawing with the map given in the chapter and note the differences in shape, size, and position.

Note: This is a practice activity to improve map-reading and spatial memory skills. There is no single 'correct' drawing — the goal is to improve with practice.

This is a map-labelling activity.

Continents to be labelled (7 total):

1. Asia – largest continent; eastern hemisphere, northern part
2. Africa – second largest; below Europe, straddles the equator
3. North America – western hemisphere, northern part
4. South America – western hemisphere, southern part
5. Antarctica – southernmost continent, around the South Pole
6. Europe – northwestern part of the Eurasian landmass
7. Australia – southeastern hemisphere, smallest continent

Oceans to be labelled (5 total):

1. Pacific Ocean – largest ocean; between Asia/Australia and the Americas
2. Atlantic Ocean – between the Americas and Europe/Africa
3. Indian Ocean – south of Asia, between Africa and Australia
4. Southern Ocean – surrounds Antarctica
5. Arctic Ocean – around the North Pole, smallest ocean

Instructions for the student:

• Use the outline map provided in your textbook/worksheet.
• Write the name of each continent clearly in the centre of the respective landmass.
• Write the name of each ocean in the middle of the respective water body.
• You may use different colours to shade the continents for clarity.

Brief Justifications:

• Oxygen (1 Across): Oceans produce a large amount of oxygen through the photosynthesis of marine plants (phytoplankton).
• Continent (3 Across): A continent is defined as a large, continuous expanse of landmass.
• Asia (6 Across): India is part of the continent of Asia.
• Plastic (8 Across): Plastic waste dumped into the sea is one of the biggest sources of ocean pollution.
• Antarctica (10 Across): Antarctica is the coldest continent on Earth, located at the South Pole.
• Greenland (2 Down): Greenland is the world's largest island, located in the North Atlantic/Arctic Ocean.
• Tsunami (4 Down): A tsunami is a series of huge, destructive ocean waves usually caused by underwater earthquakes.
• Australia (5 Down): Australia is the smallest continent in the world.
• Pacific (7 Down): The Pacific Ocean is the largest and deepest ocean on Earth.
• Island (9 Down): An island is a landmass completely surrounded by water but smaller than a continent.
