Question

What causes atmospheric pressure?? ​

Answer 1

Answer:

At sea level, standard air pressure in millibars is 1013.2. ... This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.
