The Thermosphere and the Ionosphere ________ Because ________

The thermosphere and the ionosphere ________ because ________.

A) overlap the absorption of high energy electromagnetic radiation that generates the high temperatures in the thermosphere also ionizes the gas molecules in this region of the atmosphere
B) overlap photochemical reactions in this layer separate protons from neutrons,thereby creating charged particles
C) do not overlap only the outermost layer of the atmosphere-the ionosphere-receives enough energy for ionization to occur
D) do not overlap only the outermost layer of the atmosphere-the ionosphere-receives enough energy for photochemical reactions to occur
E) overlap the processes of molecular heating cause the atmospheric particles to ionize-to burst into space.
