Assertion (A): Heat absorption capacity of air is more in the lower layers than in upper layers.
Reason (R): Air on the surface of the earth is denser and contains more carbon dioxide, water vapour and other gases.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R does not explain A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true and R is the correct explanation of A.
Explanation — The lower layers of the atmosphere are denser and contain more carbon dioxide, water vapour, and dust particles, which absorb and retain more heat. Therefore, the heat absorption capacity is greater in the lower layers than in the upper layers.
