Which statement is most appropriate about the relationship between the thermosphere and ionosphere?
Answer and explanation
Correct answer: A large part of the ionosphere is found in the thermosphere
Option A is correct. The ionosphere is a region defined by ionised particles rather than a completely separate temperature layer, and much of it overlaps the thermosphere. Solar ultraviolet and X-ray radiation removes electrons from atmospheric atoms and molecules. This region affects radio-wave propagation and auroras; it is not another name for the troposphere or an ocean-only feature.
