It extends to 600-700 km above earth's surface
The thermosphere is the outer layer of the earth's atmosphere. It extends from 80 kilometers above the earth's surface to outer space.
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.
The Earth's atmosphere extends anywhere from 250-400 miles off the surface, depending on where you are standing. Near the equator, it is thicker due to the heat from the surface and cloud reflection, and the high moisture and humidity.

Biosphere
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.
