If a surface area has an albedo of 10 percent and clouds an albedo of 90 percent then with 70 percent cloudiness the albedo for the area is 0.7(0.9)+0.3(0.1)=0.66=66 percent. This means that 34 percent of the Sun's radiation for the area is not reflected back into space.f a surface area has an albedo of 10 percent and clouds an albedo of 90 percent then with 70 percent cloudiness the albedo for the area is 0.7(0.9)+0.3(0.1)=0.66=66 percent.

Large mammals such as pigs, bears, and deer also consume large amounts of acorns; they may constitute up to 25% of the diet of deer in the autumn.
Groundhogs are herbivores; almost complete vegetarians. They are most often seen sitting on their haunches grazing on grasses, leaves, flowers, clover, alfalfa, wheat, and rye. They like to raid people's gardens and eat farmer's cucumbers and melons. Occasionally, they will climb trees and eat an apple or nut. Surprisingly peanut butter and crackers as well.
