Question

What is the cause of atmospheric pressure?


high temperatures


low temperatures


gravity


ozone depletion

Answer 1

The correct answer is **gravity**. Atmospheric pressure is caused by the weight of the air above a given point in the atmosphere. Gravity pulls the air molecules toward the Earth's surface, creating pressure. Higher temperatures and lower temperatures can affect air density and pressure, but they are not the fundamental cause of atmospheric pressure. Ozone depletion is related to environmental issues but does not directly influence atmospheric pressure.
