1
layer containing high temperatures due to absorption of the sun's rays
2
layer above the troposphere that contains ozone
3
this is what scientists used to organize and divide the atmosphere into layers
4
layer closest to the Earth's surface; contains 90% of the atmosphere's total mass; all weather occurs here
5
coldest layer of the atmosphere; located above the stratosphere
6
outermost layer of the atmosphere (not included as a main layer in our textbook) contains almost no air molecules
7
As altitude increases, the density of the air does this
8
a gas that makes up about 78% of our atmosphere
9
the higher the this, the lower the air pressure
10
this force pulls molecules down
11
this form of water adds moisture to the air, making the dry air wet air.
12
a gas that makes up 21% of our atmosphere
13
air is made of matter and therefore has a mass
