Mountain ranges affect climate. a.

Why does the air cool and rain on the windward side of a mountain?

21.

The Coriolis Effect deflects the planetary (prevailing) winds and ocean currents of the world from traveling in straight lines. Therefore, all of the ocean currents in the northern hemisphere move in clockwise motions and, winds are deflected to the right in the northern hemisphere. It is the opposite for the southern hemisphere. Play this game , and then explain, what causes this effect to happen.
