What is the relationship between temperature and air pressure?

Back

As temperature increases, air pressure decreases.

Front

What is the effect of altitude on air pressure?

Back

Air pressure decreases as altitude increases.

Front

What is the role of gravity in air pressure?

Back

Gravity pulls air molecules towards the Earth, creating pressure.

Front

How does air pressure affect weather patterns?

Back

Differences in air pressure lead to wind and weather changes.
