Explanation:

The taiga is located in the Northern Hemisphere, between the temperate forests and the tundra. It occupies large areas of Eurasia and North America, creating the largest forests in the world. The forests are dominated by coniferous trees. The taiga has short but warm summers, very short transitional periods, and a very long winter. The winters are characterized by large amounts of snow and very low temperatures, so much so that certain places in Siberia have lower temperatures even then Antarctica.
