Ionization in the thermosphere mainly occurs due to what?
Answer and explanation
Correct answer: Due to the effect of solar radiation
The governing concept is photoionization in the upper atmosphere. High-energy ultraviolet and X-ray components of solar radiation can remove electrons from atoms and molecules, producing ions and free electrons in the thermosphere and related ionospheric region. Therefore option C is correct. Rainfall, river evaporation, and ocean waves are lower-atmosphere processes and do not supply the required energy for this widespread ionization.
