The clouds, weather, and humans are all in a thin layer of atmosphere called the _______________.

• stratosphere
• crust
• hemisphere
• troposphere

The layers of the atmosphere keep the earth warm, just a jacket keeps you warm. We call this _______________.

• gravity
• the greenhouse effect
• air pressure

Which of these items is NOT a property of air?

• It takes up space.
• Gravity does not affect it.
• It can be condensed.
• It has weight.

Air is more and more thin as you go higher in altitude because there is ___________ at a high altitude.

• less gravity and less air pressure
• more gravity and more air pressure
• more snow and more gravity
• more water vapor and more air pressure

Which of these clouds is featherlike?

• cumulus
• stratus
• cirrus
