Question

Assertion (A): Block weathering commonly takes place in the deserts.

Reason (R): The daily range of temperature is low in the deserts.

Options

• 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

A is true and R is false.

Explanation:

Block weathering commonly takes place in deserts due to high diurnal temperature range (large daily temperature variations) causing physical disintegration of rocks. The reason stating the daily range of temperature is low in deserts is incorrect, as deserts actually experience a high daily temperature range which causes block weathering.
