Yes, in a process called atmospheric evaporation. Mostly this affects the amount of Hydrogen in the upper atmosphere. But as the the Earth has an ice-trap elevation (where water gets frozen out and sent back down) not too much hydrogen gets into the upper atmosphere to be ionized and evaporated off.

The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.

The Earth's gravity.
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.
A meteor. Technically, a "meteor" is the flash of light itself. Once the rock hits the Earth's surface (IF it survives) it is called a "meteorite".
The pocket of air that surrounds the earth is called the earths Atmosphere
earths average air pressure is 1013mb where as mars average air pressure is 7mb
No necessarily people but people's cars and houses with electricity and gas, polutes the air of the Earths causing it to heat up. The heat VERY SLOWLY begins to escape the Earth but at a VERY SLOW rate.
Mostly by earth itself
No, it won't. Air is pulled in atmosphere by earth's gravity.
The air arround Earth has usually the same speed as the rotating Earth itself. That is much different to camparing that with a ship on a river, where you move much faster to the sea by the water stream than to the well-spring of the river.
