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.
