Why air pressure is higher at sea level than at top of a mountain?

Air pressure is higher at lower altitudes due to the weight of all of the air above it. The height of the top of the atmosphere is uniform, but the bottom of the atmosphere must follow the contours of the top of the crust, so there is more air above a point at sea level than there is above a mountain top.
because at sea level there is much more air above you pushing down
In essence, it's because the number of air molecules decrease with increased altitude. This is because molecules have mass, and anything with mass is pulled down towards Earth by gravity.

On top of a mountain, however, there are fewer gas molecules stacked on top of each other, so the air pressure is lower.

∙ 14y agogravitational force changes with height above sea level. The higher you go, the less gravitational influence (and the less you feel the weight). However, it is not enough to feel the difference whether you are at sea level or on a mountain.

Hope this Helps!!:)

∙ 15y agobecause the distance to the centre of the earth is closer.. thus stronger pull of gravity. F=Gm1m2/r^2 that's the force of gravity..so smaller 'r' produce greater force

∙ 12y agodo you remember astronauts on the moon are always floating and bouncing around? so that explains why the gravitational pull is stronger on sea level

∙ 11y agoIn simple terms, air pressure is the weight of the column of air over any given location. At higher elevations there is less air over you, and thus less pressure.

∙ 13y agoit depends on how much you weigh

When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
Yes
Would you expect the air pressure in the valley that's below sea level to be higher or lower than air pressure at sea level?
I would expect it to be lower.
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
Is sea level pressure the same as air pressure?
Assuming you are talking about air pressure, atmospheric pressure is created by the weight of the air resting against the earth. the higher up you go, the less air stacked on top of itself, and the pressure is less, until there is no more air at all (space). The pressure of air at sea level is relatively the same around the world because of all the water flows to the same level. this obviously changes with storms and hurricanes - as those move some of the air out of the way. So if you were to go below sea level, there would be more air on top of you, and the pressure would be higher. In death valley (well below sea level) the atmospheric pressure is much higher than at sea level. To answer the question, No, pressure is not negative below sea level. It is greater than at sea level.
Why does water boils at lower temperatures than in a valley?
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower. In a valley, the air pressure is greater, which allows water to reach a higher temperature before boiling. At higher altitudes, where the air pressure is lower, the boiling point of water decreases.
Predict whether water would boil on top of a mountain at a higher or lower temperature than at sea level?
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.
Does the sea have more air pressure than the mountain?
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.
Why Poes water on top of a mountain boil at a lower temperature than at sea level?
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.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
Why is air pressure greater at a low altitude such as sea level than at a high altitude such as at the top of a mountain?
Air molecules are pushed closer together at sea level because the column of air pushing down is higher, and will tend be even higher at locations below sea level.Although there are constant variations in air pressure due to weather, lower altitudes will generally have a higher pressure than higher altitudes.
Why doeswater boil at a low boiling point on top of a mountain and a higher boiling point in a pressure cooker?
This is because the boiling point of any fluid increases as the pressure acting on it is increased. Atmospheric pressure on top of a mountain is lower than normal atmospheric pressure. Conversely, by not allowing steam to escape, the pressure above the water in a pressure cooker is allowed to build up to a much higher level.
Would you expect the air pressure in a valley that's below sea level to be higher or lower than air pressure at sea level?
The air pressure must be higher in a valley below "sea level". The air mass above this point is more than at sea level.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
Yes
Air pressure is lower at the top of a mountain than at sea level?
Yes.
Why is pressure higher at sea level than a mountaintop?
Because it is duhhh
How is the pressure on Mount Everest different from the pressure at sea level?
it is higher up on Mount Everest so it has less pressure than at sea level
Is air pressure greater at sea level or on top of a mountain?
Air pressure is greater at sea level because there is more air above that is pressing down. Any atmosphere is more dense at the surface of the planet than at locations higher in altitude. (Areas that are lower than sea level will generally have still higher atmospheric pressure.)
