Air pressure is the weight of the air above you. When you ascend to some altitude
above the Earth's surface, part of the air is beneath you, so the weight of the air
above you, and therefor the pressure where you are, is reduced.
Exactly the same reason that the pressure on the football player in the middle of the
pile-up is less than the pressure on the guy with the ball, at the bottom of the pile.
There is more air pressure at a beach compared to the top of a mountain. Air pressure decreases with increasing altitude, so the air pressure at the top of a mountain is lower than at sea level like a beach.
On top of a mountain
The top of a mountain has lower air pressure, not greater air pressure, compared to lower elevations. This is because the higher you go in elevation, the thinner the atmosphere becomes, leading to lower air pressure due to decreased atmospheric density.
As a person moves from the base to the top of a mountain, the air pressure decreases. This is because there is less air above you at higher altitudes, resulting in lower pressure due to decreased atmospheric density.
no, at bottom
Air pressure decreases as altitude increases, so at the top of a mountain, the air pressure is lower compared to the bottom of the mountain. This is because there is less air above pushing down on the air below at higher altitudes.
As you move from the base to the top of a mountain, the air pressure decreases. This is because the weight of the air above decreases with elevation. At higher altitudes, there are fewer air molecules above, resulting in lower pressure.
The top.
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.
The air pressure will decrease as the person moves from the base to the top of the mountain. This is because air pressure decreases with higher altitude due to the decreasing density of air molecules as elevation increases.
There is less air pressure on top of a mountain because the weight of the air above is less due to the thinner atmosphere at higher altitudes. This causes the air molecules to be more spread out, resulting in lower pressure.
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
