The different layers of the atmosphere. The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
The atmosphere is a thin blanket of gases that surrounds the Earth. The Earth's atmosphere comprises nitrogen, oxygen and various trace gases. There are four layers in the atmosphere, each of a different temperature: troposphere, stratosphere, mesosphere and thermosphere. Definition of atmospheric pressure.

Atmospheric pressure determines the weather, which occurs in the troposphere.
