A substance can absorb or release heat energy by the process of radiation, convection, or conduction. Radiation refers to the transfer of energy through emission of electromagnetic waves or the movement of particles. An example of radiation is the Sun’s rays. This type of heat transfer does not require direct contact between objects. Convection, on the other hand, involves the hotter fluid rising while the colder fluid sinks. Convection occurs when you boil water in a pan. Lastly, conduction is a heat transfer that occurs as a result of temperature difference between two objects in contact. Heat is transferred from the hotter region to the colder region. Conduction occurs when ice melts in your hands.

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.
