Question

Assertion (A): Absolute humidity is the actual amount of water vapour present in a given volume of air.

Reason (R): Absolute humidity decreases from the equator towards the poles.

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:

Absolute humidity is defined as the actual amount of water vapour present in a given volume of air. It is measured in grams of moisture per cubic meter of air. Warm air can hold more moisture, so absolute humidity tends to decrease as we move from the equator (warmer) towards the poles (colder) because colder air holds less water vapour.
