Hi Mr. Wood, how did your experiment go? This is Megan N from your period 3 class. Sorry I posted this late, but I am answering the questions from the board. 1.The factors that cause the area to be tundra are the temperature and precipitation in the area. 2.In a warmer climate, more plants will be able to grow and the summers would be warmer. 3.There are no large trees in the area because the soil is too frozen for large trees to grow and the climate is too cold. I think you or Mr. P said that the main trees there are white & black spruce trees.
