Which substance has a high albedo? B) White Sand
Explanation:
The albedo is the amount of energy that is reflected by a surface. It is determined by the refletivity of that surface. Albedo can range from 0 (no reflection) to a value of 1 (100% reflection). Generally, dark surfaces have a low albedo and light surfaces have a high albedo. Liquid water is considered to have a low albedo, like dark rock and rich soil.
