Explanation:

Natural gas is a hydrocarbon gas which occur under the surface of earth. The natural gas is primarily composed of methane. Also contain carbon dioxide, hydrogen, helium and sulfide. It is formed by the decomposition of organic matter generated after the decaying plants and animals materials. The organic matter remains exposed to heat and pressure under the surface of earth. It takes millions of years to form natural gas under the surface of earth.

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.
