Which statement is true?

• The troposphere has the highest temperature because of the distance from the Sun
• The troposphere has the highest pressure because gravity keeps the air down.
• The exosphere has the highest temperature because of the distance from the Sun
• The exosphere has the highest pressure because gravity keeps the air down.

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

Why are some layers warmer than others?

• they get hotter the higher up you go
• some layers contain gases that can absorb the sun's energy
• some layers closer to the sun are hotter
• there is no wind in the upper atmosphere
