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. 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.

The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to

Very high up, the Earth's atmosphere becomes very thin. The region where atoms and molecules escape into space is referred to as the exosphere. The exosphere is on top of the thermosphere.

The exosphere is almost a vacuum. The "air" is very, very thin there. When air is thin, it doesn't transfer much heat to objects in the air, even if the air is very, very hot. One definition
