Question

Where isthe air pressure the greatest, sea level or on a mountaintop?

Answer 1

Sea level.  Less air pressure at elevation.

Answer 2

Sea-level of course.

Answer 3

sea level because you have all the "spheres"weighing down on u.on a mountain top it become harder to breath because there are less are particles ~they are being weighed down to the sea level.

Answer 4

Sea Level - the more atmosphere above you, the greater the air pressure. At the top of a mountain there's a lot less atmosphere between you and space ...

Answer 5

Sea level.... it's the same principle as to why water pressure higher at deeper depths. Sea level is relatively "deeper" than mountaintop.

Answer 6

Sea level would have the greatest air pressure, unless the mountain is submerged and the peak was at sea level, then they would both have the same air pressure.

*(captndave should watch out for those sea level mountains, or the ones that are just below the surface, they could do damage to his vessel and his reputation on the high seas....)

Answer 7

Sea Level.

Answer 8

Sea level

Answer 9

Between the two?  Sea level, particularly the Dead Sea.

There is more air to weight down the closer to the center of the earth you'd go.

Answer 10

The air pressure is GREATER at sea level than on a mountain top. On Earth, the air pressure is GREATEST at the bottom of the deepest body of water.

Here are some facts that may help your understanding. Barometric pressure, air pressure and atmospheric pressure all have roughly the same meaning. Barometric pressure is more commonly used when referring to air pressure relating to the weather. Atmospheric pressure is more commonly used when referring to air pressure under water (even though it is under water, it is still air pressure).

Some examples are: At 18,000 feet above sea level, the air pressure is 7.35 psi., at sea level, it is 14.7 psi., and at 100 feet depth in fresh water, the pressure is 59 psi. There are some variables. Salt water is more dense than fresh water so the pressure at a given depth is higher in salt water. Atmospheric conditions will modify the air pressure at any given altitude.

 

Answer 11

C-level

Answer 12

there isnt air the sea

Answer 13

Sea level - the atmoshpere is also affected by gravity (just like everything else).  The heavier molecule sink to the bottom of the atmosphere and the ligher molecules rise to the top.  

Since oxygen is a heavy molecule, there is less of it the higher you go.  That is why people who climb mount everest need tanks of O2.

Answer 14

air pressure has to do with the amount of air above a certain point.. sooo .. if a mountain is higher up then the ocean ..it means there is less air above pushing down.. less air = less pressure... therefore there is more air pressure at sea level because.. more air above..

hope this clears it up for you gl !
