The mixture of gases surrounding the Earth. The Earth's atmosphere consists of about 79.1% nitrogen (by volume), 20.9% oxygen, 0.036% carbon dioxide and trace amounts of other gases. The atmosphere can be divided into a number of layers according to its mixing or chemical characteristics, generally determined by its thermal prop...
(Learning Modules / Geography / Weather forecasting) The blanket of gases that envelope the earth. Most known planets have an atmosphere, although earth's is a unique composition.
One atmosphere is 14.7 pounds per square inch (105Newtons per square meter); the average atmospheric pressure at sea level on Earth.
