The Atmosphere is a body of gasses that surround the earth. The atmosphere is made up of lots of different chemicals, those mainly being 79 % of nitrogen and 21% of oxygen with a small amount of other gasses such as carbon dioxide (3).
The Atmosphere protects planets from different long-wave and short-wave radiation which come from the sun, also known as solar radiation.
In the Atmosphere there is also different circulation that occur which have an effect on the climate of the earth.
The Atmosphere structure
The Atmosphere is split into different zones which have different names and different reactions that occur.
The Troposphere
The troposphere is from ground level to 12 km up and is the area where humans live. This area is important because it is where the Ozone hole and where weather happens. This is also the area in which Air-planes fly.
The Stratosphere
The Stratosphere is from 12 km to 50 km. This layer blocks short wave radiation that comes from solar radiation. If there was no stratosphere, the biosphere wouldn't have any organisms that had soft parts, like human skin. This is because short-wave radiation is the same size as our skin cells so they can interact and damage cells.
The Mesosphere
The Mesosphere is 50-90 km and is the area where shooting starts and meteors burn up.
The Thermosphere
The Thermosphere is 90 km to an undefined place as it gradually dissipates. This is a really hot upper layer with low density.
