Atmosphere Study Guide
1)Label the layers of the atmosphere in the diagram on the left.
2) In which layer are we? __Troposphere____
3) In which layer does weather occur?__ Troposphere ___
4) In which layer of the atmosphere is there ozone?
____Stratosphere__________________________
5) What does ozone protect life on Earth from?
____________ultra violet light___________________________
6) In which layer of the atmosphere do meteors disintegrate?
__mesosphere______
7) If thermo means heat, what happens to air temperature as you
increase in altitude in the thermosphere? (does temperature
increase or decrease in the thermosphere)__increase__
8) Above which layer does outer space lie?
______Exosphere____________
9) What happens to air pressure as you INCREASE in
altitude? ___air pressure decreases______
10) Name four things that make up air (make up the atmosphere)
__Nitrogen________,__Oxygen____,___solids
___liquids__
11) Explain why the atmosphere stays around the Earth and
doesn’t just float away. __gravity__________
The layers of air that surrounds the Earth are all called
_atmosphere__.
12) What are pollutants? _materials that harm living things___
Describe two human activities that release pollution? _burning
fossil fuels to make cars run and to make power plants
run____________________________________________

13) Why is there the greatest amount of air pressure in the
troposphere? _Troposphere has 4 layers above it pressing down
on the troposphere._
___________________________________________________
14)In the boxes above, write down the
percentages of oxygen, nitrogen, and other
gases which make up air.
14) What is kinetic energy? __the energy of motion___
15) What does kinetic energy have to do with conduction? __The movement of molecules touching other molecules__
16) What is solar energy? __energy from the sun______
17) What is radiation? _energy that travels in rays or waves____
18) What is conduction? _the transfer of energy through contact___
19) What is convection? _the transfer of energy in a circular movement due to different densities in a liquid or gas__
20) Vacuum with balloon BEFORE
all the air is pumped out
Vacuum with balloon AFTER
the air is pumped out
Where was the air pressure higher AFTER the air was pumped out of the vacuum chamber?__inside the balloon__
Where was the air pressure lower after the air was pumped out of the vacuum chamber? _in the vacuum chamber
Why did the size of the balloon increase after air was removed? The air pressure inside the balloon is higher than in
the vacuum chamber. High pressure moves to low pressure
This is Steve. He likes to blow on paper. Does moving
air have higher or lower pressure? _lower__
If Steve was blowing across the top of the paper, but
the paper moved UP, where was the air pressure
lower? On top of the paper
Where was the air pressure higher? Under the paper
Why did the paper move UP? Moving air has less air
pressure and the paper was pushed up by the
higher pressure under the paper
Label the diagram on the left with the following (high
pressure, low pressure and arrow showing the
direction air is pushing):
