Thermosphere

Within the thermosphere, temperatures rise continually to well beyond 1,000 degrees C.

The exosphere is the highest layer of the atmosphere. It extends from the top of the thermosphere up to 10,000 kilometers.

The thermosphere is located above the mesosphere and below the exosphere.

The mesosphere may be described as the earth's intermediate or middle atmosphere, which separates the thermosphere above from the ozonosphere (or stratosphere) below, both of which are responsible for absorption of most of the ultraviolet part of the solar radiation and preventing it from reaching the earth's surface.
