Explain why air pressure is a result of Earth's gravity?
Air pressure decreases as you move away from Earth's surface. The higher up you go, the thinner the air becomes. Thinner air means less density and/or less pressure. This is t…he reason passenger airplanes need to have "pressurized cabins". Fighter jet pilots also need to wear pressurized suits and have a supply of oxygen on-board. Hope this helps!
a high pressure system moves clockwise, while a low one moves counter clockwise. high pressure systems move down and out, and low pressure systems move in and up.
There is a lot of air above you when you're on the earth's surface, so gravity makes air compress the air you have at sea level.
The air pressure differences result mostly from the uneven heating of earth's surface.
Answer Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric …pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
there is less oxygen and the molecules are more spread out
All mass attracts all other mass, thats a fact. The force due to gravity between the earth and another object, is dependent on their combined mass (earth and object), and the …square of the distance between the centres of gravity.
Imagine this scenario: a pyramid of cheerleaders. The ones at the bottom feel more pressure, because there's more people on top. The ones on top feel less pressure because the…re's less stuff on top of them. Now think about your question, if you're @ the bottom, there's more stuff on top of you.
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.
That has nothing to do with properties of air. "Low pressure" means there isn't much pressure, it's as simple as that.
The elevation, i.e. radius from the center of the Earth, is not constant around the Earth. You have mountains and you have oceans, with widely varying elevation. Also, the rad…ius of the Earth at the equator is larger than the radius at the poles, also making a difference in elevation. Recall that gravity is proportional to the masses of the two objects, i.e. you and the Earth, and inversely proportional to the square of the distance between them, i.e. the elevation. Also, while it is convenient to simplify the graviometric representation of the Earth to a point located at its center, there are variations in density at various points which can cause variation in gravity, not just due to elevation.
Air does have a weight! And it is because of gravity! Note that this is per definition true because weight is only defined in the presence of gravity. Perhaps you are confus…ed about why the air is up in the atmosphere and not down here on the ground with us? This has to do with air pressure. You see, materials don't like to be compressed, which is what gravity tries to do. Gravity tries to compress the air to the ground, but faces increased air pressure as it does so. Basically what happens is that the air particles repulse each other and thus tend to drive them apart. This force increases if you force the particles to be closer to each other. As gravity tries to pull air down, the air pressure increases which counter balances the pull of gravity. In the end a stable system is formed where the air pressure is highest down near the ground and lowest up in the upper lays of the atmosphere. The air particles up in the atmosphere do feel gravity, but if they would move down they would feel an increased air pressure which pushes them up again!
Wind because it moves horizontally.
