Hi Mr. Wood!!! It's Alyssa Telepnev from period 3 and I think I have the answers to the 3 questions. 1. Location and temperature cause this area to be tundra because the sun isn't hitting it at a less-direct angle. 2. If the climate warms up, plants will be able to grow. This means that there will be a lot more carbon in the air due to photosynthesis. 3. There are no large trees in this tundra area because it isn't warm enough for decomposers to live and give the soil the nutrients it needs to support large plants.
I can't wait for you to come back to CA, and please get rid of the beard before you get back :) ~Alyssa
