#### Slide 9 -Quizvraag

Pressure and depth in gases
• As with liquids, the pressure in a gas increases with depth.
• Altitude is height above sea level.
• Most people on Earth live at low altitude.

#### Slide 12 -Tekstslide

The Earth’s _____________, which we call air, is made from gases. The atmosphere extends to a height of about above sea level.
A
hydrosphere
B
atmosphere
C
geosphere
D
biosphere

#### Slide 13 -Quizvraag

A
highest
B
lowest
C
equal
D
zero

#### Slide 14 -Quizvraag

As you go higher in the atmosphere, the number of particles in of air ___________, so the concentration of gas particles decreases.
A
decreases
B
increases
C
remains constant
D
becomes zero

#### Slide 15 -Quizvraag

As you go _________ in the atmosphere, the weight of air above your current position decreases.
A
lower
B
higher
C
in the middle
D
closer

#### Slide 16 -Quizvraag

Atmospheric Pressure
• Atmospheric pressure at sea level is about 14.7 pounds per square inch. This pressure is the equivalent of the weight of two large elephants pushing on every of surface.

#### Slide 17 -Tekstslide

Effects of atmospheric pressure
• The effect of atmospheric pressure can be shown by pumping the air out of a metal container.
