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
Bottom
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.
because the air pressure is more dense
No, it is greater at the lower elevations.
No, it is greater at the lower elevations.
on the bottom of the mountainbeacause you are more below air level
At the bottom. You can think of the air pressure at a given location as being the weight of all the air in a column above it. Thus, the higher you go, the less air there is above you, and thus the lower the air pressure. In the extreme, when you rise out of the athmosphere, there is no air above you at all, and the air pressure is effectively zero - a vacuum. Air pressure is greater at the bottom of a mountain.
As you move from the bottom to the top of the mountain, the air pressure decreases.
It is the effect of air pressure. The air pressure at the top of a mountain is less than the air pressure at sea level. The effect of air pressure on a water surface is to prevent or oppose water molecules escaping from the surface. The greater the air pressure, the more heat energy is needed to allow the water molecules to escape and so at sea level the water will boil at a higher temperature than if it were on top of a mountain.
on the top of the mountain as pressure is greater so water will boil quicker
On top of a mountain
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
no, at bottom
