What do areas of high albedo have in common?

The correct answer is - lighter surface, higher reflection and low absorption of the light.

Explanation:

Albedo is the ability to reflectivity of the matter that means how much is absorbs or reflects the light. The lighter the surface higher the albedo percentage and higher reflecting ability of the matter or surface.

The lower the albedo percentage higher the absorption ability of the matter. for example icebergs have a higher albedo rate as they reflect the light.

Thus, the correct answer is - lighter surface, higher reflection and low absorption of the light.
