Best Answer

The air pressure is greatest at the surface because the weight of the air above pushes down on the air below, compressing it and creating higher pressure. As you move higher in the atmosphere, there is less air above exerting pressure, so the air pressure decreases.

Where is air pressure the greatest?

The air pressure is greatest at sea level.


Where would the air pressure be the greatest around a mountain?

The air pressure would be greatest at the base of the mountain because as you move higher in elevation, the air pressure decreases due to the thinner atmosphere at higher altitudes.


Where is air pressure the greatest in the atmosphere?

Air pressure is the amount of force exerted on an object by the atmosphere. It is greatest at sea level.It is greatest in the exosphere, due to the fact that air pressure is greater as the altitude rises; the exosphere is the highest level within the atmosphere.Air pressure is greatest in the areas that are small and enclosed. This is because there is no way to escape.


Is air pressure the greatest at the beach?

Air pressure does not vary significantly depending on whether you are at the beach or elsewhere. However, factors such as altitude and weather conditions can affect air pressure.


Air pressure is greatest because there are more molecules of air pushing down from above?

Yes, air pressure is greatest at sea level because the weight of the air above is pressing down with more force. As you go higher in altitude, the number of air molecules above you decreases, causing lower air pressure.


What air pressure is the greatest here?

Air pressure is typically greatest at sea level, where it averages around 1013.25 millibars. As altitude increases, the air pressure decreases due to the reduction in the weight of the air column above.


Is air pressure greatest in a cave?

No, air pressure is not greatest in a cave. Air pressure is highest at sea level due to the weight of the air above pushing down. In caves, air pressure is usually lower than at the surface because caves can have openings that allow air to escape.


What is the peak of a wave where the greatest air pressure occurs?

The peak of a wave where the greatest air pressure occurs is known as the crest. This is the highest point of the wave where the air particles are most compressed, resulting in an increase in air pressure.


When is air pressure greatest?

According to the ideal gas equation, PV=nRT, air pressure is greatest in systems with low volume, high temperature, and of course a lot of air.


Why is air pressures greatest at ground level?

Air pressure is greatest at ground level because the weight of the air above compresses the air molecules closer together, creating higher pressure. As altitude increases, there is less air above, resulting in lower air pressure.


Normal air pressure is greatest at?

Normal air pressure is greatest at sea level, where it is typically around 1013 millibars or 29.92 inches of mercury. As you go higher in elevation, air pressure decreases.


Where is the pressure greatest on a tire when its on the car?

Air pressure is the same throughout the tire.
