The document describes the different layers of Earth's atmosphere, which are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer where weather occurs and temperatures decrease with altitude. The stratosphere has increasing temperatures with altitude due to ozone absorption. It contains the ozone layer which absorbs ultraviolet radiation. The mesosphere is the coldest layer where temperatures decrease with height. The thermosphere is the hottest layer where temperatures increase with altitude and contains auroras and satellites. The exosphere is the uppermost layer where atoms and molecules can escape into space.

Earth atmosphere has a
series of layers, each with its
own specific traits.
 Moving upward from
ground level, these layers
are named the
troposphere,
stratosphere,
mesosphere,
thermosphere and3

5. The lowest part of the atmosphere - the part we
live in.
All weather occurs in this lowest layer.
The temperature gets colder as the distance
above the earth increases, by about 6.5°C per
kilometer.

7. 7
Air temperature increases with height due to sunlight
absorption by ozone.
As you go higher the temperature gets warmer.
Little convection and turbulence
Contains the ozone layer

Is a region of Earth’s stratosphere that absorbs
most of the Sun’s ultraviolet radiation.
Contains high concentrations of ozone molecules
(O3).

The temperature decrease with height.
The coldest layer of the atmosphere (-90°).
Meteors burn up in this layer.

High-energy, X-rays and UV radiation from the
Sun are absorbed
The hottest layer
Temperature increases with altitude (over
2000°C)
Aurora and satellites occur in this layer.

The uppermost layer of our atmosphere.
Is the atoms and molecules escape into space.
composed of very widely dispersed particles of
hydrogen and helium.
