Which statement gives an expert explanation of high temperature in the thermosphere?
Answer and explanation
Correct answer: Rarefied gases absorb high-energy solar radiation
The governing concept is absorption of energetic solar radiation in the upper atmosphere. In the thermosphere, sparse oxygen and nitrogen particles absorb ultraviolet and X-ray radiation, increasing their average kinetic energy and producing a very high measured temperature. Because the gas is extremely thin, however, an object would not necessarily experience strong heating in the everyday sense. Option D is correct; the other choices invoke condensation, monsoon clouds or rainfall, none of which explains thermospheric temperature.
