Properties of the Atmosphere

Identify what happens to air density as you increase in altitude?

• air density increases

• air density decreases

• air density stays the same

As the air temperature increases, the air's capacity for water vapor: 

• increases

• decreases

• remains the same

• is unrelated to air temperature and can either increase or decrease

What is the function of the ozone layer?

• to allow UV rays to get to Earth

• to block UV rays from getting to Earth

• To keep oxygen in

• to allow meteors to get to Earth

What happens to the density (thickness)/air pressure of the air as you increase in altitude?

• density increases

• density decreases

• density stays the same

• density disappears

What decreases with altitude throughout Earth's atmosphere?

• density

• pressure

• density and pressure

• temperature and density

The atmosphere exerts pressure because

• It has weight

• of temperature

• of elevation

• It is above ground
