Answer:
the blanket of gases that surrounds Earth and some other planets
Explanation:
The atmosphere is the layer of gases that surround and cover the Earth. It is held in place around the planet because of the gravity of it. There are few layers of the atmosphere, including the first one in which we live and where the weather occurs (troposphere).
The atmosphere helps the organisms on earth as it includes oxygen that most need for life and because it protects us from various damages, such as radiation and harmful rays. It also protects us from the meteors, as it burns them down until they have become non-harmful for the Earth and its inhabitants.
