Atmospheric science is the study of the atmosphere, its processes, and the interaction of the atmosphere with other systems, including the effects other systems have on the atmosphere and visa versa. Fields in Atmospheric Sciences include Meteorology, Climatology, and Aeronomy. Ask and answer questions about Atmospheric Sciences in this category.
Outgassing from volcanoes formed the Earth's original atmosphere. Later green plants converted large amounts of carbon dioxide in the atmosphere to create the modern atmosphere with roughly 20% oxygen, 80% nitrogen, and tiny amounts of other gasses.

The atmosphere is a gaseous envelope (with suspended liquids and solids) that surrounds the Earth and is held in place by gravity. The atmosphere is very thin compared to the size of the Earth. A virtual vacuum exists above an altitude of 100 miles (160 km), and breathable air is only about 6 miles …
