In which layer is ionization effective due to solar radiation even though particles are sparse?
Answer and explanation
Correct answer: Thermosphere
The governing concept is photoionization in the upper atmosphere. Although the thermosphere contains very few particles, high-energy ultraviolet and X-ray solar radiation can remove electrons from those particles, creating ions and free electrons. Therefore option B is correct. The troposphere and surface boundary layer are denser and mainly governed by weather and surface processes, not this strong radiation-driven ionization.
