Because as you get closer to the surface of the earth, the more air that is on top of you. At the top of the atmosphere, there is no air, and everything is a vacuum, where you have no weight. When you get close to the earth, the weight of the air builds until it when you're at the very lowest point of the earths surface, all the air in the atmosphere above you is pressing down.
What else can I help you with?
Why is air preassuare greastest at the earths surface?
Air pressure is greatest at the Earth's surface because the weight of the air above exerts a force on the air below. As you move higher in the atmosphere, there is less air above pushing down on you, so the pressure decreases. At higher altitudes, there are fewer air molecules, resulting in lower air pressure.
What happens when the atmospheric pressure is greatest near the Earths surface?
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.
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.
Why is air pressure greatest at the Earth's surface (the Troposphere answer?
Air pressure is greatest at the Earth's surface, particularly in the troposphere, due to the weight of the air above pressing down on it. The air molecules are denser near the surface because gravity pulls them closer to the Earth, resulting in higher pressure. As you move higher in altitude, there are fewer air molecules above, leading to a decrease in 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.
Why is air preassuare greastest at the earths surface?
Air pressure is greatest at the Earth's surface because the weight of the air above exerts a force on the air below. As you move higher in the atmosphere, there is less air above pushing down on you, so the pressure decreases. At higher altitudes, there are fewer air molecules, resulting in lower air pressure.
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 when the atmospheric pressure is greatest near the Earths surface?
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.
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
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.
Why is the air pressure greatest at the serface?
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.
