As an electron gains energy, it becomes excited and jumps to a lower energy level?

Yes if you add an energy to an electron the electron will become excited, and it will jump to its highest level then go back down releasing  energy

This is inccorect. When an electron gains energy and becomes excited it jumps to a higher energy level. When an electron jumps to a lower energy level it de-excites.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
