Explain to Mark how composting can help reduce greenhouse gases

Explanation:

Compositing is the regulated breakdown of organic matter by microbes, aerobically. The major gas released from composting is carbon dioxide. This is different from landfills and manure piles where most of the breakdown of the organic matter happens, anaerobically because less oxygen penetrates the matter. Composting involves deliberate aeration of the decomposing matter. Anaerobic breakdown methane releases methane gas even more than carbon dioxide. Methane is four times more potent as a greenhouse gas than carbon dioxide. This is why composting is a good agricultural practice for mitigating climate change as compared to the use of landfills.

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.
