Why can temperature be very high in the thermosphere?
Answer and explanation
Correct answer: Because high-energy solar radiation is absorbed there
The thermosphere contains sparse particles that absorb high-energy solar ultraviolet and X-ray radiation. This absorption gives the few particles very high kinetic energy, so the measured temperature can be extremely high. However, the air is so thin that it would not feel as hot as dense air at the same temperature. Option B is correct; soil, heavy rain, and boiling ocean water are not present there and do not explain the heating.
