Explain why air pressure is a result of Earth's gravity?
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.
Under controlled situations , as the temperature increases the air pressure decreases.:)
Air pressure is a atmospheric pressure. Air pressure creates: 1. Different climate 2. Creation of rain 3. Creation of wind 4. It prevents small asteroids to come t…o the earth
Due to gravity, our Earth has an atmosphere in the first place. Otherwise, the gases would quickly diffuse into space. Also, gravity makes the atmosphere more dense closer t…o the Earth - the upper layers push down against the lower layers.
The simplest explanation is that air is composed of gases. Gases are composed of molecules. Molecules have mass. The closer molecules get to the center and bottom of the gravi…ty well, the more closely packed they become, because successive "layers" pack down on those below, piling up. The weight of the gases on top of those on the bottom compress those on the bottom.
Yes, it is.
due to the gravitational pull of earth we are now having atmosphere,ie;the RMS(root mean squre)velocity of gases in earth is less than escpe velocity of earth,so gases cannot …escape fom earth,then its ctually temperature,density and hight determins the air pressure
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.
Gravity is an entirely separate entity which is a consequence only of the mass of the earth itself. In fact, the atmosphere presses down because gravity is pulling on it.
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 confu…sed 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!
Air has mass, and gravity pulls anything with mass. The gravity of the earth "pulls" air down towards it's center.
Gravity is a function of mass and distance. So, no air pressure does not affect gravity.
It is gravity.
Yes, the atmospheric pressure is very important.
