Caption: Earths atmosphere is made up of layers. The lowest ones (troposphere, stratosphere, mesosphere) have a relatively homogeneous composition but widely varying temperatures. In the thermosphere (80500 km altitude), the temperature rises considerably, since this layer absorbs considerable solar radiation. Above it is the exosphere, a zone where the few remaining molecules of air escape Earths gravity.
