Gravity
atnosphere gets held back by earths gravtional field
The Earth's gravitational attraction prevents gasses from escaping into outer space.
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.
Gravity
Outer planets are made of gas because they formed far from the sun where it was cooler, allowing volatile gases like hydrogen and helium to condense and accumulate. The enormous gravitational forces of these planets then captured and retained these gases, preventing them from escaping into space.

The strong gravitational pull of the gas giants, such as Jupiter and Saturn, keeps the gases from escaping into space. The immense mass of these planets creates a powerful gravitational force that holds the gases in their atmosphere. Additionally, the presence of a magnetic field around these planets also helps in trapping the gases and preventing them from escaping.

Earth's gravity holds its atmosphere in place, preventing it from escaping into space. Gravity pulls gases like nitrogen and oxygen towards the planet's surface, creating the atmospheric pressure that sustains life on Earth. Without gravity, these gases would dissipate into space.

They do. Greenhouse gases in the atmosphere retain heat rising from the surface of the earth and stop it escaping into space. This keeps the earth comfortably warm and has done for thousands of years.
The greenhouse effect (greenhouse gases in the atmosphere) keep the earth warm enough for life. They prevent some heat escaping out to space, particularly at night.
The natural process that keeps the Earth's atmosphere warm is called the greenhouse effect. This occurs when certain gases in the atmosphere trap heat from the sun, preventing it from escaping back into space.
