Question

E. Long answer type questions
1. Explain the main features of Fold, Block and Volcanic mountains.​

Answer 1

Answer:

Fold Mountains Block Mountains

When sediments deposited on a seabed are subjected to compression, they are gradually squeezed and folded, after which they form huge chains of mountains called fold mountains. Sometimes, because of compressional forces the, horizontal layers of rocks break down into several pieces called blocks.

The upfold is called an anticline and the downfold is called a syncline. The mountains that are formed because of the upliftment are called block mountains and the subsided blocks are called rift valleys.

Example: The Himalayas Example: The Rhine Valley enclosed by the Vosges

Answer 2

Fold mountains= it is the most common type, they form when two or more tectonic plates collide.

Block mountain= also called as fault block, it is formed through geological process pushing some rocks up and others down.
