Air Pressure Quiz

What is the primary reason air exerts pressure on objects?

• Air is weightless.

• Air has no mass.

• Air molecules are stationary.

• Gravity pulls air molecules towards the Earth's surface.

Why does Deanna experience less air pressure on the mountain compared to Marnie at sea level?

• Mountains have more air pressure.

• Marnie is heavier.

• There is less air above Deanna.

• Deanna is closer to the sun.

How does temperature affect air pressure?

• Temperature does not affect air pressure.

• Cold air has more pressure due to more molecules.

• Warm air has more molecules than cold air.

• Cold air has less pressure than warm air.
