The thermal energy in a heat engine is used to move a piston. which best describes why this is possible? the increase in thermal energy results in an increase in pressure. the decrease in thermal energy results in an increase in pressure. the increase in thermal energy results in a decrease in pressure. the decrease in thermal energy results in a decrease in pressure.

answer: a chemical reaction

explanation:

im not wrong

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.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
