Put the following surfaces in descending order from those surfaces that have the highest albedo to those surfaces that have the lowest. I. clouds II. ice sheets III. forest IV. asphalt pavement a. IV-III-II-I b. III-I-IV-II c. II-IV-I-III d. II-I-IV-III

d. II-I-IV-III

Explanation:

The albedo of the ice sheets s the highest and that of the forest is the least or the lowest.  The forest covers about the 12% of the landscape and the 29 of the surface area of the planet thus have an albedo of 0.017. While that of the asphalt payment is the 0.18 to 0.35.
