What holds the gases of the atmosphere near earth surface?

Gravity holds the gases of the atmosphere near Earth's surface. The force of gravity pulls the gases towards the Earth, preventing them from escaping into space.


Which force holds the atmosphere to the earth?

The force that holds the atmosphere to the Earth is gravity. Gravity is the force of attraction between all objects and it keeps the gases in our atmosphere close to the Earth's surface.


What holds all the gases around earth?

Earth's gravity is what holds all the gases in the atmosphere around the planet. Gravity exerts a force that prevents the gases from escaping into space, creating the atmosphere that surrounds the Earth.


What keeps gasses here on earth?

Gravity is what keeps gases on Earth. The planet's gravitational force pulls gas molecules towards the surface, preventing them from escaping into space. The stronger the force of gravity, the more likely gases are to remain in the atmosphere.


What does the earth's gravitational attraction prevent gases from doing?

The Earth's gravitational attraction prevents gasses from escaping into outer space.


What is the atmosphere bound to the earth by?

What keeps the oxygen inside earth?

Gravity is what keeps oxygen (and other gases) from escaping Earth's atmosphere. The gravitational force of Earth is strong enough to hold on to gases in its atmosphere, including oxygen. This allows for the maintenance of a stable and breathable atmosphere on the planet.


Why does the atmosphere stay around the Earth?

The atmosphere stays around the Earth due to gravity. Gravity is the force that pulls the gases in the atmosphere towards the Earth's surface, keeping them from escaping into space.


Why can gravity pull on the suspended particles and gases in the air?

Gravity pulls on all objects with mass, including suspended particles and gases in the air. The force of gravity causes these particles and gases to be attracted towards the Earth's center, giving rise to phenomena such as sedimentation and atmospheric pressure.
