• Creates meteors in the sky
• Keep ocean waters cold

What happens to the air pressure the higher up in space you go?

• the air pressure increases
• the air pressure decreases
• the air pressure stays the same
• there is no air pressure

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.
