The thermosphere is the layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere. Within this layer, ultraviolet radiation causes ionization. Called from the Greek θερμός meaning heat, the thermosphere begins about above the Earth. At these high altitudes, the residual atmospheric gases sort into strata according to molecular mass . Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation. Temperatures are highly dependent on solar activity, and can rise to . Radiation causes the atmosphere particles in this layer to become electrically charged, enabling radio waves to bounce off ...
