Layers of the Atmosphere

Layers of the Atmosphere

Introduction: The Earth is surrounded by a relatively thin layer of air. The air consists of a mixture of gases, mostly nitrogen and oxygen, that we rely on for survival. This blanket of gases that provides us with air to breathe and protection from harmful radiation from the sun, is the Earth's atmosphere.

The Earth's atmosphere is the region of gases extending from the planet's surface into space.  

The Earth's atmosphere has five major layers. These layers are determined mainly by changes in temperature with increased altitude. The troposphere is the layer closest to the Earth. Weather occurs in this layer. Above the troposphere are the stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique properties and plays a crucial role in supporting life on Earth.
