When can faults form in fold mountains?

Can folds form in block mountains? Find the reasons and discuss.

Observe the diagrams and read the explanation regarding the characteristics of various faults given below. Identify the faults and match each of them with their characteristics.

A) Normal fault: It results when a portion of land slides down along the fault plane and when the exposed portion of the plane faces the sky.

B) Reverse fault: It results when a portion of the land is thrown upward relative to other side of the land. In such situation, the fault plane faces the ground.

C) Tear fault: At times, the rock strata on either sides of the fault plane do not have vertical displacement. Instead, movement occurs along the plane in horizontal direction.

D) Thrust fault: When the portion of the land on one side of the fault plane gets detached and moves over land on the other side. The angle of fault plane is generally lowless than 45°.

Choose the correct option by identifying the correct correlation in the sentence:

This landform develops due to the depositional work of wind. The windward slope of this landform is gentle.

Answer in detail:

Explain different types of faults.
