Pressure
Science Review Game
How does
temperature affect
the amount of water
vapor in the air?
Explain how
convection currents
are produced in the
air.
Describe what happens
to air molecules when
air is heated.
What is the source of
energy that causes
the wind to blow?
What is atmospheric
pressure and what
causes it?
Is atmospheric
pressure higher on a
mountain top or at
sea level. Why?
A student opened a bottle of
water in the mountains,
drank the water, and put on
the cap. When he returned
to Redwood City, the bottle
was crushed. Explain why.
In which direction
does atmospheric
pressure push?
What happens to the
molecules in a sealed
syringe when the
plunger is pushed in?
Below is a picture of a closed
container with a piston. Complete the
drawing of the second container to
show what happens to the molecules
of air when the piston pushes down.

Where is the
atmosphere densest?
Why?
The graph shows temperature data from two containers.
One container had 100 ml of water and the other had
100 ml of dry soil. Each container was placed in the
sunshine for 20 minutes and then in the shade for 20
minutes.
Which
container,
A or B, had
the dry
soil?
Explain.
