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 things in the atmosphere absorb energy from the sun? - water vapor and carbon dioxide absorb infrared radiaton. - the ozone layer in the stratosphere absorbs most of the ultraviolet radiation. -clouds, dust, and other gases absorb energy from the sun.
