  The atmosphere is really no different to e.g. water or rock, but it’s components of the Earth which are a gas. The gas is still affected by gravity, and so it’s pulled down to the surface of the Earth, where it sits, that’s why we run out of atmosphere as we go up, because the gravity pulls the gas down to the Earth where it sticks.
