I. Answer the following questions in detail
1. Mention the classification of landforms.
a. First order landforms
Continents and oceans are grouped as first order landforms. The vast land masses on Earth are called Continents and huge water bodies are called Oceans.
There are seven continents. They are Asia, Africa, North America, South America, Antarctica, Europe and Australia. Asia is the largest continent, whereas Australia is the smallest one.
b. Second order landforms
The second order landforms are categorised as mountains, plateaus and plains.
c. Third order landforms
Third order landforms are formed on mountains, plateaus and plains mainly by erosional and depositional activities of rivers, glaciers, winds and waves. Valleys, beaches and sand dunes are some examples of third order landforms.
2. Write a note on plateaus.
Plateaus are the elevated portions of the Earth that have flat surfaces bounded by steep slopes.
The elevation of plateaus may be a few hundred or several thousand metres.
The Tibetan Plateau is the highest plateau in the world. It is called the ‘Roof of the world’.
The flat topped part of the plateau is called Tableland.
The plateaus are generally rich in minerals.
The Chotanagpur Plateau is one of the mineral rich plateaus in India.
The Deccan Plateau in peninsular India is of volcanic origin.
3. Plains are highly populated. Give reasons
Plains are flat and relatively low-lying lands.
Plains are usually less than 200 metre above sea level.
Most plains are formed by rivers and their tributaries and distributaries.
They are most suitable for human inhabitation.
Hence, they are the highly populated regions of the world.
The oldest civilisations like the Mesopotamian and the Indus civilisations developed in river plains.
The Indo-Gangetic plain in North India is one of the largest plains in the world.
The plains formed by river Cauvery and Vaigai are important plains found in Tamil Nadu.
Coastal plains are the low lying lands adjacent to oceans and seas.
4. Give the important features of the Pacific Ocean.
The Pacific Ocean is the largest and deepest ocean on the Earth.
It covers about one-third of the Earth’s total area and spreads for about 168.72 million sq.km.
It is bounded by Asia and Australia in its west and North America and South America in its east.
It stretches from the Arctic Ocean in the north to the Southern Ocean in the south.
This ocean’s shape is roughly triangular with its apex in the north at the Bering Strait which connects the Pacific Ocean with the Arctic Ocean.
The deepest point of the Mariana Trench is located in the Pacific Ocean. A chain of volcanoes is located around the Pacific Ocean called the Pacific Ring of Fire.
5. Write about the importance of oceans.
The Earth looks blue when we see it from space.
This is because two-thirds of it is covered by water.
The water is found in oceans and seas.
Oceans are vast expanses of water.
Seas are water bodies partially or fully enclosed by land.
There are five main oceans in the world.
