What is Understanding Earth about?
The atmosphere is a mixture of gases surrounding a planet, primarily composed of 78% nitrogen and 21% oxygen, which supports and protects living organisms. It consists of several layers, including the Troposphere where weather occurs, the Stratosphere containing the ozone layer, and the Thermosphere where auroras happen. Meteorologists study the atmosphere, which interacts closely with other Earth systems and varies in temperature and pressure with altitude.
