The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous ray from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.
Definition:
The atmosphere consists mainly of nitrogen and oxygen, with smaller proportions of other gases such as carbon dioxide. The amount of carbon dioxide in the atmosphere is a balance between processes such as photosynthesis, respiration and combustion.

The atmoshere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space.
1) The troposhere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer.
2) Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.
3) Meteors or rock fragments burn up in the mesosphere.
4) The thermosphere is a layer with auroras. It is also where the space shuttle orbits.
5) The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere.
