The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere.

The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.

What is the force that holds the gases of the atmosphere around Earth?

The sun is being hold by gravity, in the sun there are like magnets which creates our solar system, the suns extreme gravity is what holds everything but the magnet fields is what makes us move around the sun but the core of the earth is what makes us rotate. The suns extreme Gravity is what basically holds its gasses.


How does the earth hold its Atmosphere?

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.


Why does the moon have big temperature changes while earth dose not?

because the Earth has more of an atmosphere, and the Moon does not. the atmoshpere holds in heat and cold, so on the moon there is not anything to keep the temperature stable


This holds a planet's atmosphere close to its surface?

Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.


What are mercury Venus earth and mars atmospheres made of?

Mercury has a surface pressure that is near enough zero (or a vacuum), the planet holds no real atmosphere due to its small size. There are some trace gases at the surface, but not what one would call a proper atmosphere.
