D
savanna.
Explanation: 

Detailed explanation-1: -Heat gained by the layers of air at or near the earth’s surface from radiation or conduction is usually transferred to the upper atmospheric layers by the process of convection. Thus convection is the transfer of heat in the atmosphere by the air current.

Detailed explanation-2: -Convection currents transfer thermal energy through many fluids, not just hot water in a pot. For example, convection currents transfer thermal energy through molten rock below Earth’s surface, through water in the oceans, and through air in the atmosphere.

Detailed explanation-3: -Convection occurs when heat is carried away from your body via moving air. If the surrounding air is cooler than your skin, the air will absorb your heat and rise. As the warmed air rises around you, cooler air moves in to take its place and absorb more of your warmth. The faster this air moves, the cooler you feel.
