FAQs on Major Landforms of the Earth: Overview Video Lecture - Class 6

1. What are some major landforms found on Earth?
Ans. Major landforms found on Earth include mountains, plateaus, plains, valleys, and deserts. These landforms are formed by various geological processes such as tectonic activity, erosion, and deposition.
2. How are mountains formed?
Ans. Mountains are formed through tectonic activity, which involves the collision or separation of tectonic plates. When two plates collide, they can form fold mountains, where the rock layers are folded and uplifted. Another type of mountain formation occurs when one tectonic plate is forced beneath another, creating volcanic mountains through volcanic activity.
3. What is a plateau?
Ans. A plateau is a flat or gently sloping elevated land area that is characterized by its relatively flat top and steep sides. Plateaus can be formed by various geological processes such as volcanic activity, erosion, or tectonic uplift. They are often found between mountain ranges and can cover large areas of land.
4. How are plains formed?
Ans. Plains are formed through the deposition of sediment over a long period of time. They can be formed by the erosion of mountains and the subsequent deposition of sediment in nearby low-lying areas. Plains can also be formed by the deposition of sediment by rivers, wind, or glaciers.
5. What are some examples of famous valleys on Earth?
Ans. Some examples of famous valleys on Earth include the Grand Canyon in the United States, the Nile Valley in Egypt, the Yosemite Valley in California, and the Kathmandu Valley in Nepal. Valleys are typically formed by the erosion of land by rivers or glaciers, creating a low-lying area between mountains or hills.
