With a force called gravity. Each atom and molecule of the atmosphere has an atomic weight, which keeps it from floating away into space.

What holds the atmosphere to the earth?
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.
Earths position in the atmosphere?
Earth isn't in the atmosphere - the atmosphere is part of Earth.
How is Earth's atmosphere different from the atmosphere on Mars?
Earth's atmosphere is almost 200 times thicker than the atmosphere of Mars. The atmosphere of Earth is primarily nitrogen and oxygen, while the Martian atmosphere is primarily carbon dioxide.
Why is the water on the moon frozen?
The moon doesn't have the kind of atmosphere that can hold heat like Earth. Therefor, it is too cold for water.
How does the composition of earth atmosphere differ from the composition of the atmosphere of the gas giants?
earth has people in it's atmosphere
What holds the earth atmosphere?
Gravity hold the atmosphere to the Earth. But other factors do cause earth to loose some atmosphere to space continuously.
Why can the Earth hold its gases in its atmosphere?
Gravity.
Does the gravity hold the atmosphere around the earth?
yeah
What holds the atmosphere to the earth?

What do tornadoes tell you about the earth?
Tornadoes demonstrate that Earth's atmosphere can hold quite a bit of energy.
Does earth's moon have oxygen?
No, its gravity is too low to hold an atmosphere.
Where on earth besides in a greenhouse does the greenhouse effect occur?
In the atmosphere. The greenhouse effect refers to the situation in the atmosphere where gases hold on to the heat rising from the earth.
Why does the earth remain warm after sunset?
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.
Does the sun keep the earth warm?
The sun warms the earth. The heat (energy) from the earth then heats the air.
When gases in the atmosphere form a blanket around the earth to hold heat in?
not liquids or solids?
Does the moon have a thick atmoshee?
Luna, the Earth's moon, has no atmosphere at all. Its force of gravity is too small to hold an atmosphere to its surface.
Why is the worlds atmosphere so big?
The planet Earth has a sufficiently large mass, and correspondingly large gravitational field, to enable it to hold on to a large atmosphere.
