The tops of mountains have the consistently lowest air pressure, because density decreases with altitude. The simplest explanation is that there is "less air pushing down" when you are at a higher altitude.
It decreases as you move away from the earth surface
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
The planet with an atmospheric pressure similar to that 30 km above Earth's surface is Venus. At an altitude of about 50 km above Venus, the atmospheric pressure is comparable to Earth's surface pressure.
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Standard atmospheric pressure at sea level is about 14.7 PSI. So, then what is the pressure at about 5,645 feet below the surface of the earth?
Atmospheric pressure varies over Earth's surface, mainly due to differences in temperature, altitude, and weather conditions. This variation in air pressure creates different weight of air known as atmospheric weight.
Pressure
The measure of force with which air molecules are pushing on earths surface is called air pressure. At sea level, at what we call standard atmospheric pressure, the pressure is about 14.696 PSI, or about 29.92 inHg, or about 760 mmHg. This is 101.324
When atmospheric pressure is greatest near the Earth's surface, it usually indicates stable and fair weather conditions. High pressure systems generally bring clear skies, low humidity, and light winds. This can lead to pleasant weather conditions in the area.
Venus and Mars. The difference is that Venus atmospheric pressure is around 93 times that of Earths, while Mars' atmospheric pressure is only 0.7% of Earths.
