The gases in the atmosphere do not float off into space due to the Earth's gravitational pull, which keeps them bound to the planet. Additionally, the atmosphere is held in place by the balance of forces, including the kinetic energy of gas molecules that causes them to collide and create pressure. This pressure helps maintain the density of the atmosphere, preventing the gases from escaping into space. Finally, the thermal structure of the atmosphere, including temperature gradients, also influences the behavior of these gases, contributing to their retention.

How is air pulled towards earth?
During the formation of the Earth, various gases were released from the surface, including carbon dioxide, nitrogen, and water vapor. Once the Earth reached a large enough mass, it had enough gravity that these gases didn't drift off into space; they were held to the surface by gravity. Earth's magnetic field also helps to keep the atmosphere on Earth, by shielding it from solar winds that would otherwise bombard the atmosphere and send its gases into space. The Moon has no atmosphere because its mass is too low, and thus it doesn't have enough gravity to hold onto an atmosphere. In addition, it has no significant magnetic field. Mars may have once had a much denser atmosphere, but it lost its magnetic field billions of years ago, and solar winds eroded the atmosphere until it became very thin, like it is today.
How many cows would it take to burn the atmosphere off?
Sorry, that question needs to be clarified. What are you trying to understand that would require such an answer?
How would you propel a spacecraft in space?
if you mean a NASA rocket ship you would have boosters that drop off after you get so high then you are basically at the mercy of gravity to get you the rest of the way then you basically float in mid space.
What will happen if the earth loses its gravity?
If Earth were to suddenly lose its gravity, everything not securely anchored to the ground would float off into space, including the atmosphere and oceans. The loss of gravity would cause cataclysmic changes to the planet's structure, leading to widespread destruction.
How can the atmosphere be polluted?
Gasoline and diesel automobiles and trucks pollute as do industries which burn coal. Some industrial processes such as oil refineries give off gases which pollute. Cows give off methane.
The atmosphere is held in place by Earth's?
The atmosphere is held in place by Earth's gravity. Gravity keeps the gases of the atmosphere from drifting off into space and creates a force that pulls them towards the planet's surface. Without gravity, the atmosphere would dissipate into space.
Gases in Mercury's atmosphere?
Mercury has no atmosphere. Cosmic rays from the sun burn the gases off.
The atmosphere is held in place by Earth's .?
gravity
Why does the air not not float into space?
Gravity holds the air in Earth's atmosphere. The gravitational force between Earth and the air molecules is strong enough to keep them from floating out into space. Additionally, the atmosphere is continuously replenished by processes like volcanic activity and plant respiration.
What happens when we let all of the Earth's helium float off into space?
If we let all of Earth's helium float off into space, we will not be able to replace it. Helium is a very important resource because it can be cooled to very low temperatures and exist as a liquid. It's used in MRI machines to cool the superconducting magnets, for instance. When used for cryogenic purposes, it's allowed to boil off into the atmosphere, where it floats up into space and is lost forever.
What prevents gases flying off onto space?
gravity.
What keeps us from foating off into the sky?
Our Earth's gravity ensures we don't float off into space.
Is Friction the most important force on Earth?
and because we would float off into space
Is it safe to sleep in a car in a garage with the car off?
Yes, because when a car is off, no noxious gases are released. However, if the car is on in a closed space, the space will eventually fill up with poison gases and it will not be safe.
If there was no gravity why do people say there would be no oxygen?
Gravity holds things down to Earth (or any other body in space). The oxygen only stays on earth because of this gravity. Without gravity, oxygen and our whole atmosphere would just disperse and float off into space.
What gas is given off into the atmosphere due to the split of water?
There are two gases: hydrogen and oxygen.
Explain how earth's mass is related to its ability to have an atmosphere?
The Earth has an atmosphere because it has the gravity necessary to keep the gases from floating off into space. The more mass a planet has, the more gravity it has, and the more gravity it has, the thicker an atmosphere it can sustain.
