Albedo is a measure of how much solar radiation a surface reflects back into space. It is measured on a scale from 0 to 1. Surfaces like fresh snow have a high albedo (0.9), meaning they reflect most of the sun’s heat. Dark surfaces like the ocean or forests have low albedo (0.1), meaning they absorb most of the heat. ANSWER: (C) The Albedo
