WebThe ionosphere sometimes becomes disturbed as a reaction to some types of solar activity and, as a result, radio wave propagation may be degraded or disrupted. … WebThe ionosphere is an atmospheric layer located at an altitude of about 50 kilometers and 500 kilometers. It has an extremely low density and is traversed by strong radiation as ultraviolet light, which in turn is highly ionized. This ionization causes the electronic bonds of the atoms to break down producing ions of different charges. church classes called https://shoptoyahtx.com
