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.
Also known as the âSpiny Ant-eaterâ and âShort-beaked Echidnaâ, this species is found widely around Australia and in Papua New Guinea and Indonesia. Echidna species and the Platypus are the only animals in the Monotremata order: mammals that lay eggs. In parts of Papua New Guinea, Echidnas are hunted for food. Locally, predators include dogs, eagles and Tasmanian Devils. Echidnas move slowly, which means they are at risk on our roads. You can help to reduce the road toll of these native animals by driving carefully and, if it is safe, driving around any Echidnas you find crossing the road. Do not pick them up â their spines are very sharp.
