The Himalayas are an example of which type of mountains?
- A.Block mountains
- B.Volcanic mountains
- C.Young fold mountains
- D.Residual mountains
Correct answer
Explanation
The correct answer is C, Young fold mountains. The Himalayas were raised when the northward-moving Indian plate collided with the Eurasian plate and the sediments of the shallow Tethys Sea between them were compressed into great folds and thrust upward. The process continues, so the range is still rising and the belt remains earthquake-prone. Option A is wrong because block mountains, such as the Vosges and the Black Forest, are formed when a block of land stands up between two faults. Option B is wrong because volcanic mountains, such as Mount Kilimanjaro or Barren Island in the Andamans, are built of erupted material. Option D is wrong because residual or relict mountains, such as the Aravalli and the Nilgiris in India, are worn-down remains of much older ranges rather than young structures.

- A.Terai
- B.Bhabar
- C.Bhangar
- D.Khadar

Read the full explanation →The older alluvium of the Northern Plains, lying above the flood level and containing lime nodules called kankar, is known as:
- A.Khadar
- B.Bhabar
- C.Bhangar
- D.Terai
Show answer
Bhangar is the older alluvial deposit of the Northern Plains. It forms terraces that stand above the present flood level, so fresh silt no longer reaches it, and long leaching has left calcareous concretions called kankar in its profile.
