Which atmospheric region helps in long-distance radio communication?
Answer and explanation
Correct answer: Ionosphere
The ionosphere contains free electrons and ions that can refract, reflect, or otherwise influence certain radio waves. This interaction allows some signals to travel beyond the ordinary line of sight and supports long-distance communication, especially at suitable frequencies. The troposphere and stratosphere do not provide this characteristic ionized layer, and exospheric dust is not the relevant mechanism.
