Which substance has a high albedo? a.) liquid water b.) white sand c.) dark rock d.) rich soil

The correct answer is B.) White Sand

Explanation:

The term "albedo" is used to describe the amount of radiation a surface reflects, this is also related to how fast a surface increases its temperature. In general terms, the lighter the surface is the most albedo it has as dark/black bodies absorb all radiation. For example, white snow has an albedo of 80% while dark wet soil has radiation of 10%; also, in the case of water, this has a low albedo (around 10%). According to this, the substance that has a high albedo is white sand as this is a light surface and therefore it is expected it reflects most of the radiation it receives, around 50% (or even more) albedo.
