Because the atmosphere was the first thing we learned about in our unit, I thought it would be good to review some of the material to refresh our minds about the atmosphere:
In our atmosphere there is:
78% Nitrogen
21% Oxygen
0.9% Argon
0.03% Carbon Dioxide
So obviously, there is the most nitrogen in our atmosphere and the least carbon dioxide.
The difference between good ozone and bad ozone:
Good ozone is protects us from UV rays and radiation.
Bad ozone is formed from pollutants and actually depletes the good ozone layer.
There are 5 layers in our atmosphere:
Troposphere: This is where we live. Weather occurs here.
Stratosphere: It is DRY here because there is little to now water. The ozone layer is here.
Mesosphere: This is the coldest layer. Air pressure is low here.
Thermosphere: This is the warmest layer. Auroras are here.
These 5 layers are based on:
1. Temperature changes
2. Chemical composition
3. Density
HOPEFULLY THIS WAS HELPFUL!
