The ionosphere is the layer of the atmosphere that reflects radio waves. This effect is caused by the ionization, or electrical charging, of the gas particles present in the upper atmosphere by X-rays and ultraviolet rays emitted by the sun.
What layer of the atmosphere has the ozone layer that absorbs harmful ultraviolet radiation? Stratosphere What layer of the thermosphere has communication and weather satellites and the international space station orbits in this layer?
