Question

Assertion (A): The block mountains are formed as a result of vertical movement of the earth’s crust.

Reason: The block mountains are formed by the divergent movement of the tectonic plates.

पर्याय

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

• Block mountains form when land moves up or down along faults, so A is true.
• This vertical faulting happens because tectonic plates move apart (diverge) and create tension, so R is true.
• Since divergence causes the vertical movements that form block mountains, R correctly explains A.
