5
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 the underlying mesosphere keeps the warm air there
because of the gases trapped in these layers

What would happen if Earth had no atmosphere?
Earth would not have nights.
Earth would not have days.
The days would be cold and the nights would be hot.
The days would be hot and the nights would be cold.
17
How is the troposphere warmed?
The Sun warms Earth's surface, which warms the air above it.

the formation of the solar system
21
What is the most abundant gas in Earth's atmosphere?
oxygen
hydrogen
carbon
nitrogen
22
Why are there fewer molecules of air up in the mountains?
because air pressure increases as you go higher
because air is too heavy
because air pressure is the same in all layers of atmosphere
