FAQs on Major landforms of the Earth - 1 Video Lecture - Social Studies (SST) Class 7 (Old NCERT)

1. What are the major landforms on Earth?

Ans. The major landforms on Earth include mountains, plateaus, plains, hills, and valleys. These landforms are formed by various geological processes like tectonic activity, erosion, and deposition.

2. How are mountains formed?

Ans. Mountains are formed by the movement of tectonic plates, which collide or separate from each other. When two plates collide, they push against each other, causing the Earth's crust to fold and form mountains. Examples of mountains include the Himalayas, the Andes, and the Rockies.

3. What are plateaus?

Ans. Plateaus are flat, elevated landforms that are characterized by steep sides. They are often found between mountains or can be formed by the upliftment of the Earth's crust. Plateaus can be classified as either volcanic or erosional plateaus, depending on the process that formed them.

4. How are plains formed?

Ans. Plains are flat or gently rolling landforms that are formed by various geological processes such as erosion, deposition, and weathering. They are often found in coastal areas or near river valleys where sediments are deposited over time. Plains are ideal for agriculture due to their fertile soil.

5. What are the characteristics of valleys?

Ans. Valleys are elongated depressions between mountains or hills, often formed by the erosive action of rivers or glaciers. They typically have a V-shape or U-shape depending on the type of erosion. Valleys are often fertile due to the accumulation of sediments brought by the rivers or glaciers.
