Question

what is albedo?○ the amount of $\text{co}_2$ a surface absorbs○ the angle of sunlight hitting earth○ the measure of how much sunlight a surface reflects○ the amount of heat stored in spil

Explanation:

Albedo is a term used in environmental and Earth sciences to describe the reflectivity of a surface with respect to sunlight. The other options describe unrelated concepts: CO₂ absorption is not albedo, the angle of sunlight is solar incidence angle, and heat stored in soil is unrelated to surface reflectivity.

Answer:

The measure of how much sunlight a surface reflects
