The portion of incident radiation (energy) without heating that surface reflected back from a surface of a body is called: Correct Answer Albedo

The ratio between the total solar radiation falling (incident) upon a surface and the amount reflected without heating the earth, is called ALBEDO (expressed as a decimal or as a percentage). The earth's average albedo is about 0.4 (40%); that is, 4/10 of the solar radiation is reflected back into space.
