Layers of the Earth's Atmosphere
The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space.
1) The troposphere 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. And the ozone layer absorbs harmful rays from the Sun here.
3) Meteors 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.

At very high altitudes, the atmosphere becomes very thin. The region where atoms and molecules escape into space is referred to as the exosphere. This is the true upper limit of the Earth's atmosphere.

The exosphere is very nearly a vacuum. The technical definition of the temperature of a gas (even a very thin one) is related to the average speed of particles (atoms and molecules). Since most of the
