FAQs on Classification of Mountains Video Lecture - Geography for UPSC CSE

1. What are the different types of mountains?
Ans. Mountains can be classified into five main types based on their formation processes. These types are fold mountains, fault-block mountains, dome mountains, volcanic mountains, and plateau mountains.
2. How are fold mountains formed?
Ans. Fold mountains are formed through the process of tectonic plate collision. When two tectonic plates collide, the layers of rock between them are compressed and forced upward, creating folds and uplifted mountain ranges over time. The Himalayas are a famous example of fold mountains.
3. What causes the formation of fault-block mountains?
Ans. Fault-block mountains are formed due to the movement of tectonic plates along faults. When tension causes the Earth's crust to crack, blocks of rock are uplifted or tilted, forming fault-block mountains. The Sierra Nevada range in the United States is an example of fault-block mountains.
4. How do volcanic mountains form?
Ans. Volcanic mountains are formed by the accumulation of volcanic materials such as lava, ash, and pyroclastic flows. When a volcano erupts, the molten rock (magma) is expelled onto the Earth's surface, eventually building up a mountain. Examples of volcanic mountains include Mount Fuji in Japan and Mount Vesuvius in Italy.
5. What are plateau mountains and how are they formed?
Ans. Plateau mountains are elevated flat areas of land with steep sides. They are formed through the process of uplift and erosion. Over millions of years, tectonic forces uplift large, flat areas of land. Subsequent erosion by rivers and glaciers carves steep sides, resulting in the formation of plateau mountains. The Colorado Plateau in the United States is a well-known example of a plateau mountain.
