Earthatmosphere
The Earth's atmosphere is the layer of gases surrounding our planet that is held in place by gravity. It is crucial for life on Earth, providing breathable air and regulating temperature. The atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with smaller amounts of argon, carbon dioxide, and trace gases.
The atmosphere is divided into several layers, each with distinct characteristics. The troposphere is the lowest
Further up are the mesosphere, where meteors burn up, and the thermosphere, which is very hot but
The atmosphere plays a vital role in the Earth's climate system. Greenhouse gases like carbon dioxide trap
