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.
When you approach a tree check its branches and the ground around it for acorns. All oaks, but no other trees have acorns as their fruit. Acorns vary in shape from species to species, but ultimately they all pretty much look like acorns.These fruits provide tasty treats for birds, so studying trees is a good way to study animal life as well.f course there are other factors to consider when identifying an oak tree, like the shade and texture of its bark, and its shape when viewed in its entirety. These are just some of the details to look forward to as you continue with your learning journey.
