How does the ionosphere help in radio communication?
Answer and explanation
Correct answer: It can reflect or bend radio waves
The ionosphere contains electrically charged particles produced by solar radiation. These ionised regions can refract, reflect, or otherwise influence certain radio waves, allowing some signals to travel beyond the normal line of sight and over long distances. It does not make clouds permanent, stop raindrops, or change Earth’s rotation. Thus, option A correctly states its communication role.
