Air, like water, finds its own level, so high up theres less of a column of air (and therefore less weight) above your head, resulting in lower pressure

Where is the highest air pressure?

air pressure is the highest near the earths surface


Dose air in the atmosphere exert pressure on earths surface?

Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.


Is air pressure weak or strong at earths surface?

weak and strong,it depends


Which weather condition most directly determines wind speeds at Earths surface?

Air pressure Gradient


What happens to air pressure as you move higher above earths surface?

The air is thinner the higher you go.


Which planet s air pressure is 30 km above the earths surface?

mercury


Why does air pressure decrease as altitude increase?

The atmoshere is held around the earth by gravity. Gravitypulls gas molecules in the atmosphere towards the earth'ssurface causing air pressure. air pressure is the measure of the force with which air molecules push on a surface. Air pressure is at the strongest at the earths surface because more air is above you. So, altitude (the distance from sea level) increses, air pressure decreses. think of air pressure as a human pyrimid,the people at the bottom of the pyramid can feel all the weight and pressure of the people on top. air pressure works in a similar way.


What causes the pressure of the atmosphere?

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.


What is a barometer used to measure?

the weight of the air pressing down on the earths surface is known as air pressure.this pressure is measured using a barometer


What happens to air pressure as the distance from Earths surface increases?

As the distance from Earth's surface increases, the air pressure decreases. This is because there is less air above pushing down on the air below. The decrease in air pressure is why it becomes harder to breathe at higher altitudes.


Do currents of cold sinking air produce regions of higher pressure or lower pressure at the earths surface?

Currents of cold sinking air produce regions of higher pressure at the Earth's surface. As air sinks, it compresses and becomes denser, leading to an increase in pressure at the surface. This high pressure often leads to fair weather and clear skies.


The force with which air pushes on the earth's surface is called?

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
