Question

Assertion (A): The process of conduction heats up the lower layers of the atmosphere.

Reason (R): The lower layers of the atmosphere are in contact with the land.

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

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

Explanation:

The lower layers of the atmosphere get heated by conduction because they are in direct contact with the Earth’s surface (the land). Heat from the warm land transfers directly to the air molecules touching it, warming the lower atmosphere.
