The albedo of an object is the extent to which it ___ ___ from the Sun

Explanation:
Albedo is the proportion of sunlight that a surface reflects. So the blank is “reflects light.” It isn’t about what is absorbed, what passes through, or the surface emitting heat. Those relate to absorption, transmission, and thermal emission, respectively. In practice, bright surfaces like fresh snow reflect most sunlight (high albedo), while dark surfaces like asphalt absorb more energy (low albedo). Albedo is a dimensionless measure, often expressed from 0 to 1 (or as a percentage), describing how much of the Sun’s energy is reflected back rather than absorbed.
