Layers of Earth's Atmosphere

The video provides an overview of Earth's atmosphere, a protective layer of gases surrounding the planet. It explains the composition of the atmosphere, primarily nitrogen and oxygen, and its role in supporting life by absorbing solar energy and protecting from radiation. The atmosphere is divided into layers: the troposphere, where weather occurs; the stratosphere, containing the ozone layer; the mesosphere, where meteors burn; and the thermosphere, where satellites orbit. The exosphere is the outermost layer. Each layer has distinct characteristics, such as temperature variations and specific phenomena like auroras and lightning types.
