The atmosphere refers to the layer of gases that surrounds a planet, retaining heat and supporting life. Specifically, on Earth, the atmosphere is composed primarily of nitrogen (about 78%) and oxygen (about 21%), along with small amounts of other gases such as carbon dioxide, argon, and water vapor. The atmosphere plays a critical role in regulating the planet's climate, protecting life from harmful solar radiation, and facilitating weather patterns. It consists of several layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with distinct characteristics and functions.
