    The air close to the ground is warmer because the earth's surface is what heats the atmosphere, for the most part. Terrestrial radiation accounts for much of the warming of air near the Earth’s surface. The further
    away from the earth's surface we go, the cooler the atmosphere.

    The Roaring Forties is the name given to strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 50 degrees. The strong west-to-east air currents are caused by the combination of air being displaced from the Equator towards the South Pole and the Earth's rotation, and there are few landmasses to serve as windbreaks.

    Correct Option: A
