Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
The partial pressure of oxygen on Mt Everest would be approximately one-third of the partial pressure of oxygen at sea level, assuming a constant composition of air. This decrease is due to the decrease in atmospheric pressure at higher elevations. This lower partial pressure of oxygen can lead to decreased oxygen availability for breathing at high altitudes.
as you move up from sea level, the atmospheric pressure decreases. At higher elevations, theres less air above you so therefor less air pressure. When the air pressure outside your body decreases, the air pressure inside also decreases (slowly).
Atmospheric pressure is highest at sea level, where the weight of the air above exerts the greatest force. Consequently, you would expect higher atmospheric pressure near low-lying regions like sea level and lower pressure at higher altitudes.
Air in high mountains is thinner because there is less atmospheric pressure as you go higher in elevation compared to air at sea level. The lower pressure at high altitudes makes it harder to breathe and can lead to altitude sickness if not acclimated. Additionally, there may be lower humidity levels in high mountain air compared to air at sea level.
Sea level pressure, sometimes as mean sea level pressure.
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
The atmospheric pressure at the level of the Dead Sea is approximately 15.47 PSI.
the atmospheric pressure below sea level is highter (novanet)
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
It is greater.
The answer is sea level. Because atmospheric pressure decreases when altitude increases
The atmospheric pressure at sea level is approximately 101,325 pascals.
Beacouse of lower weight of air.
The partial pressure of oxygen on Mt Everest would be approximately one-third of the partial pressure of oxygen at sea level, assuming a constant composition of air. This decrease is due to the decrease in atmospheric pressure at higher elevations. This lower partial pressure of oxygen can lead to decreased oxygen availability for breathing at high altitudes.
Atmospheric pressure is a measure of the amount of air pressing down on the earth. This would be highest at the surface of the earth. At 5000 meters, there are 5000 meters of air below you, so that is considerably less air.
