Solution
The correct option is C
Both 1 and 2
Explanation:
Statement 1 is correct: The atmosphere is indirectly heated by terrestrial radiation from below in the troposphere, a layer which is closest to the Earth’s surface. Therefore, the warmest temperatures in the troposphere are near the surface with the coldest temperatures being at the top of the troposphere.
Statement 2 is correct: Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Hence, The variation in temperature over the seas is less compared to land.
