S6: Only a small part of insolation is absorbed and converted into thermal energy. P: Its rays are transmitted in various wavelengths of the solar spectrum, mainly in the ultraviolet, visible, and infrared bands. Q: When components of the solar spectrum reach the earth, the insolation is partially absorbed and converted to thermal energy. R: The amount of energy the earth receives from other celestial bodies is negligible by comparison. S: Radiant energy from the sun that strikes the earth is called insolation.
