Question

How does the atmosphreric pressure change as we move upward from the earth?

Answer 1

The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. ... Since most of the atmosphere's molecules are held close to the earth's surface by the force of gravity, air pressure decreases rapidly at first, then more slowly at higher levels.

Answer 2

HEYA FRIEND:

Air pressure decreases as you move higher in the atmosphere. Air, just like any form of matter has mass, and when affected by earth's gravity, weight. The weight of air is pushing down on you with a force of 1 atmosphere at sea level. As you increase elevation the air pressure is reduced because there is less air to push down on you. Just like air, water pressure increases as you increase your depth in it, or any fluid.
