Question

What is the cause of atmospheric pressure?​

Answer 1

Answer:

Air pressure is caused by the weight of the air molecules above. Even tiny air molecules have some weight, and the huge numbers of air molecules that make up the layers of our atmosphere collectively have a great deal of weight, which presses down on whatever is below. This pressure causes air molecules at the Earth’s surface to be more tightly packed together than those that are high in the atmosphere.
