What does the air consist of?

• molecules
• helium
• density
• weather

In what direction(s) does air exert pressure?

• everywhere
• no where
• there is no pressure
• downward

What is atmospheric pressure?

• weight of wind

• weight of air pushing down on an area

• weight of the time air takes to move

How is atmospheric pressure related to air density?

• higher density equals lower pressure and lower density equals higher pressure

• as density gets higher or lower atmospheric pressure does nothing

• higher density equals higher pressure and lower density equals lower pressure

What causes the relationship between atmospheric pressure and density?

• Earth's orbit

• Earth's rotation

• Earth's gravitational pull

Air pressure is greatest when near Earth's surface because?

• The air molecules are farther apart.
• The air molecules are closer together.
• Air molecules collide.
• Air molecules are tightly packed.

• False

What direction do air particles move to create wind?

• High pressure-> Low pressure

• Low pressure-> High pressure

• High pressure-> High pressure

• Low pressure-> Low pressure
