It extends about 75 miles.
Earth's Atmosphere
The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Early attempts at studying the nature of the atmosphere used clues from the weather, the beautiful multi-colored sunsets and sunrises, and the twinkling of stars. With the use of sensitive instruments from space, we are able to get a better view of the functioning of our atmosphere.
mesosphere
Troposphere. This is the lowest section of the earths atmosphere that contains 75% of the earths atmosphere by mass and 99% of the earths water vapour. This section of the atmosphere starts at the surface and extends 7-20km up, the thickness depending largely on where you are in the world.
Biosphere
the earths surface.
When Earths surface is heated it radiates some of the energy back into the atmosphere as "Infrared Radiation."

Thermosphere, it is also the atmosphere with the highest temperatures.
The thermosphere is the outer layer of the earth's atmosphere. It extends from 80 kilometers above the earth's surface to outer space.
stratosphere
Biosphere
the objects which enter the earths atmosphere are being pulled down towards the earths surface due to the earths gravity. And so it leads to falling falling of large objects from the space on the surface of the earth.

The troposphere is the layer of the atmosphere in which we live, it's also the lowest layer of the atmosphere and extends to 12 miles up from the earths surface.
