How is ionization in the thermosphere related to communication technology?
Answer and explanation
Correct answer: It can help in the propagation of radio waves
The governing concept is the interaction between charged particles and electromagnetic waves. Solar radiation ionizes gases in the upper atmosphere, and the resulting ionized region can reflect or refract some radio frequencies, helping signals travel beyond the normal line of sight. It does not remove clouds, create tides or fertilize soil; those processes have different causes. Therefore option A is correct.
