Gravity.
The main atmospheric gases that help hold the Earth's atmosphere in place are nitrogen and oxygen. These gases are constantly present in the atmosphere and provide the necessary pressure to keep the atmosphere close to Earth's surface. Additionally, small amounts of other gases like carbon dioxide, methane, and water vapor also contribute to trapping heat and maintaining Earth's temperature.
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.
In the atmosphere. The greenhouse effect refers to the situation in the atmosphere where gases hold on to the heat rising from the earth.
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
The process by which gases hold heat in the atmosphere is called the greenhouse effect. This occurs when certain gases in the atmosphere trap heat from the sun, leading to an increase in temperature on Earth. Some of the key greenhouse gases include carbon dioxide, methane, and water vapor.
Gravity hold the atmosphere to the Earth. But other factors do cause earth to loose some atmosphere to space continuously.
Earth holds its atmosphere due to the force of gravity. Gravity pulls the gases of the atmosphere towards the surface of the Earth, preventing them from escaping into space. The Earth's gravity is strong enough to hold gases like nitrogen, oxygen, carbon dioxide, and others close to its surface.
Earth is the only one we know of so far :)
Gases surround the Earth due to gravitational forces that hold the atmosphere close to the planet's surface. The gases in Earth's atmosphere are a result of volcanic activity, biological processes, and other natural phenomena, creating a protective layer that helps regulate temperature and protect life.

The Earth atmosphere is formed from gases.
It would be the MOON because Consequently, earth's first atmosphere, was shallow and sparse, composed of lightweight hydrogen(h2) and helium (he) gases. Its atmosphere and climate would have been similar to that of our moon.
