Dear Mr. Wood. Here are the answers to the 3 questions from class. Some factors that cause this area to be tundra are the low precipitation, the cold weather, and it is near the poles. With a warmer climate, the factors will change to. The precipitation will be higher, the weather will be warmer, and the seas will rise because of the melting ice shelf. The answer to the third question: there are no large trees in the tundra area because there is permafrost all over the ground and not enough water or nutrients in the ground for the trees. Your Student, Mateo
