Neither can I, which is weird, since we did a load of stuff about it in Physics on our last day of term.
Whether our physics teacher was talking total crap, I don't know. Then again, he may of been making up all sorts of rubbish just in order to survive the last day.....
Still searching google
EDIT: I've found a little bit of info;
Quote: "The thermosphere also includes the region of the Earth's atmosphere called the ionosphere. The ionosphere is the region of the atmosphere that is filled with charged particles. Elevated temperatures can sometimes cause a molecule to become ionized, therefore, the ionosphere and thermosphere can overlap.
Ionization processes release energy which heat up the upper atmosphere. So temperature increases with height in the ionosphere region to the extent that by 150-200km, the Earth's atmosphere is extremely hot compared to surface temperatures.
Different regions of the ionosphere make long distance radio communication possible by reflecting the radio waves back to Earth. It is also home to auroras and the mega-ampere currents that heat the atmosphere at high latitudes during geomagnetically active times. During storms, depletions and enhancements of ionization occur depending on the local time and geographical location.
Aeronomy is a term of recent origin which is applied to the processes, both physical and chemical, of the ionosphere.
"
Whatever we were studying (if it actually exists!) was something to do with ionization, and its effect on electrons, which some how creates sound without an actual atmosphere. Still searching....
