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.
Greenhouse Gases. Although Earth's atmosphere is 90% opaque to long wave IR radiation, the vast majority of the atmosphere is not composed of gases that cause the greenhouse effect. Molecular nitrogen (N 2) and oxygen (O 2) make up roughly 98% of our atmosphere, and neither is a greenhouse gas.
