Hope it helps ❤️✌️❤️
At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
Since most of the atmosphere's molecules are held close to the earth's surface by the force of gravity, airpressure decreases rapidly at first, then more slowly at higher levels.

sorry buddy but I can't find the answer related to the case of water ☹️
ohh....it's okay.....
don't worry
but we can use this answer in the case of water because it's same as the case of water
Yes
ya.....you are right
hmm so bye all if you
OK bye bye

The pressure was greatest at bottom and lowest at top!!!!
As atmospheric pressure depends upon density of atmosphere because with increasing density of air the atmospheric pressure also increased however, at increasing altitude the density of atmosphere decrease because earth gravitational force has pulled more as more air molecules near it. And when density of atmosphere is low at top therefore the atmospheric pressure is high at top.
I HOPE IT HELP!!
if it help mark as brainliest!
