In which layer do energetic rays from the Sun play a major role in ionization?
Answer and explanation
Correct answer: Thermosphere
The governing concept is solar ionization in the upper atmosphere. In the thermosphere, intense ultraviolet and X-ray radiation from the Sun has enough energy to remove electrons from atoms and molecules, creating ions and free electrons. This region overlaps strongly with the ionosphere. The troposphere and stratosphere are lower layers, while the hydrosphere is Earth’s water system, not an atmospheric layer.
