Quizplus · Accepted Answer

The heterosphere and ionosphere are both found in the thermosphere, which starts at an altitude of about 80 km and extends upward to about 600 km. The thermosphere is the region where the atmosphere becomes thinner and temperatures increase with altitude due to absorption of solar radiation. The heterosphere is the uppermost layer of the atmosphere, where gases are stratified by molecular weight. The ionosphere is a region within the upper part of the heterosphere where ionization occurs due to solar radiation, and it is responsible for reflecting radio waves back to Earth.
