How does the ionosphere help in long distance communication?​

Answer 1

Answer:

Because the F2 layer remains by day and night, it is responsible for most skywave propagation of radio waves and long distance high frequency (HF, or shortwave) radio communications. Above the F layer, the number of oxygen ions decreases and lighter ions such as hydrogen and helium become dominant.
