Of course it has mass!
That is why we have air pressure pushing down on your head!

There are 5 layers to the atmosphere

Fill in the Blanks
11
Troposphere
This is the lowest layer of the atmosphere
Most atmospheric air is found here
From 0 to 14 km (9mi) above the earth
Air temperature decreases the higher up you go
Almost all of weather occurs here
12
Weather exists in the troposphere!
Due to uneven heating of the earth, the troposphere is where winds and most weather occurs!

14
Stratosphere
Air temperature INCREASES as you go higher in the troposphere
This is because the ozone (O3) absorbs sunlight
This layer is 14km to 50km above the earth
The layer is very calm and makes for nice smooth flights
The OZONE LAYER is found at the bottom of the stratosphere.

16
Mesosphere
50km to 80km above the earth
Air temperature DECREASES with height above the earth
This is the coldest layer of the atmosphere!
This layer protects the earth - meteoroids usually burn up in this layer!

18
Thermosphere
the "heat sphere" goes from 80km to outer space (it's the warmest!)
Temperature increases with height above the earth
The aurora borealis (northern lights) are here
The space shuttle orbits here!
The lower part includes the ionosphere and the upper part starts the exosphere

Exosphere
550km to outer space
Air is very thin here
GPS Satellites orbit the earth here
