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.
Opossums are subject to a variety of diseases, though interestingly, rabies is exceedingly rare. Opossums are omnivorous, meaning they eat both plant and animal substances. They eat hard and soft mast: acorns, berries, and other fruits. Opossums consume insects and other arthropods, as well as bird eggs, bird nestlings, and small mammals. They have even been known to kill and eat venomous snakes (opossums are remarkably immune to snake venom). Carrion (dead animals), garbage, and even young of their own species round out an opossums diet.
