Auroras normally occur in the Earth's thermosphere.
1) The biome that is characterized by low temperatures, permafrost, and little precipitation is the tundra.
2) The latitude is the factor that explains why tundra biomes remain cold year round but taiga biomes have alternating warm and cold seasons.
3) A couple of factors that explain the difference in biodiversity between the tundra and the tropical rain forest are warmer temps in rainforests allow more animals to live and higher than average rainfalls.
