Earth's atmosphere is the layer of gases that surrounds the planet and is held in place by Earth's gravity. It extends from the surface of the Earth up to about 6215 miles (10,000 kilometers) into space.
The main force acting on a falling meteor through the Earth's atmosphere is gravity. Gravity pulls the meteor downward towards the Earth's surface, causing it to accelerate as it falls. Air resistance also plays a role in slowing down the meteor's descent as it interacts with the atmosphere.
That's gravity. Near the surface air has a density of about 1.2Kg/m^3. Air isn't that lightweight as you might think. We usually just don't lift it, but push it away, which is much easier.

Earths atmosphere? 300 miles. There is no definite boundary.
Gravity pulled it in.
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
The two are completely unrelated.

Exosphere. The layers of the atmosphere are: Space Exosphere Thermosphere Mesosphere Stratosphere Troposphere Earth
Gravity is an entirely separate entity which is a consequence only of the mass of the earth itself. In fact, the atmosphere presses down because gravity is pulling on it.
Gravity. And the meteor is on a path that intersects the orbit of 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.
