Gravity - or, more precisely lack of it ! The further away from the centre of the earth you are - the less gravity affects apply. Standard air pressure at sea-level is approximately 14 PSI - but that reduces exponentially with altitude.
It doesn't. Pressure is lower at the top of a mountain because there is less air weighing down on top of it.
As you move from the bottom to the top of the mountain, the air pressure decreases.
The higher you are in the atmosphere, the lower the air pressure. Seeing that the top of a mountain is quite high, the air pressure is low; the air is thinner. This is why you need oxygen tanks to reach the top of Mount Everest
is decreases
The air at the top of the mountain is going to be much less dense than the air at the bottom of the mountain because it is affected less by gravity.

no, at bottom
is decreases

The top.
cuz it wants to!
well a moutian if it is tall enough can reach the sky and air pressure their is 0
Air pressure decreases as height is gained. There is less air pressure at the top of a high mountain, than at sea level.
because the air pressure is more dense
