Mass, Density and Pressure
300
Where does weather occur?

400
List all the layers of Earths atmosphere (6)
Troposhere, Stratosphere, Mesosphere, Thermospehre (which is composed of Ionosphere and Exosphere)
400
The second lowest layer of earths atmospeher (this is where the ozone layer is)
Stratosphere
400
The lower part of the thermosphere
Ionosphere
500
The outer layer of the thermosphere that goes on and on into space
Exosphere
500
How does altitude effect air pressure?
As altitude increases, pressure decreases - the higher you are the thinner the air - and it makes it harder to breathe!
500
How is the atmopshere important to life?
It gives us warmth, protects us from radiation, and it keeps the earth from being hit by meteroids!
500
An instrument that measures changes in air pressure (that doesn't use liquid)
Aneroid Barometer
