3
How is the troposphere warmed?
The stratosphere warms it.
The Sun warms Earth's surface, which warms the air above it.
The gases in the troposphere absorb heat from the Sun.
The troposphere absorbs sunlight directly.
4
How does the atmosphere benefit Earth?
It creates water.
It protects Earth from the Sun's harmful rays.
It protects Earth from other planets.
It protects Earth from cold air.
5
What happened that allowed the growth and survival of green plants on earth?
human life
the formation of an ozone layer
the formation of the solar system
the formation of severe weather

What is the most abundant gas in Earth's atmosphere?
carbon
hydrogen
nitrogen
oxygen

temperature
color
wave length
air pressure
9
What does the atmosphere do?
Keeps water in liquid form
Gives us gases we need to live
Keeps us warm
Protects us from the sun
10
Why are the thermosphere and exosphere the warmest of the atmospheric layers?
because they are closest to the Sun
because the air pressure is too great
because of the gases trapped in these layers
because the underlying mesosphere keeps the warm air there
