Why is the ionosphere considered useful for radio waves?
Answer and explanation
Correct answer: Because it can reflect radio waves
The ionosphere contains many electrically charged particles produced by solar radiation. These ions and free electrons can refract, reflect, or otherwise alter certain radio signals, particularly some high-frequency waves, allowing signals to travel beyond the horizon and support long-distance communication. Hence option A is correct. The ionosphere does not remove clouds, stop rainfall, or warm the ocean.
