The trapping of the suns warmth in a planet’s lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.
4
Q
What is short-wavelength radiation
A
Radiant energy produced by the sun with wavelengths ranging from infrared through visible to ultraviolet
5
