Answer 1

Answer:

Earth is not heated in a uniform manner, there are hit and cold spots, e.g you have a desert inland the Sun heats it, hot air rises. Since there can't be a vacuum, colder air from the surroundings must fill the gap, then you get convection.

Answer 2

Explanation:

the answer is B. Convection currents drive atmospheric circulation at the global scale. The Earth is heated most intensely near the equator, where this air rises as part of the intertropical convergence zone. It then reaches high altitudes and diverges poleward as part of the Hadley cell, a permanent circulation cell in the tropics. This is the primary means in which excess energy is transported poleward via the atmosphere. This air and its energy tends to subside in the subtropics, and eventually move poleward again in the Ferrel cell of the mid-latitudes and polar cell of the polar regions through eddy diffusion.
