Surface winds on earth are primarily caused by differences in
a) air density due to unequal heating of earth's surface.
b) distances from the sun during the year.
c) rotational speeds of earth's surface at various latitudes.
d) ocean wave heights during the tidal cycle.
explain pls

Surface winds on Earth are primarily caused by differences in Air density due to unequal heating of Earth's surface. The answer is letter A. Surface currents are driven by winds that blow in certain patterns. They are caused by the Earth’s spin and the Coriolis effect. Evaporation adds water to the atmosphere. It is the change from liquid to gas wherein liquid molecules tends to go the gas phase and increases the number of molecules.

Explanation:

Causes of Different Pressure on the Earth's Exterior. Differences in pressures across the cover of the Earth are fundamentally produced by irregular heating of the surface by the Sun.
