Detailed explanation-1: -In Russia, the world’s largest taiga stretches about 5, 800 kilometers (3, 600 miles), from the Pacific Ocean to the Ural Mountains. This taiga region was completely glaciated, or covered by glaciers, during the last ice age. The soil beneath the taiga often contains permafrost-a layer of permanently frozen soil.

Detailed explanation-2: -taiga, also called boreal forest, biome (major life zone) of vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.

Detailed explanation-3: -Taiga means pure or untouched in Russian language. It is the largest biome in the world. It has spread over Eurasia and North America. Taiga is located just below the Tundra biome. Taiga biome experiences very cold winters with only snowfall.

Detailed explanation-4: -The taiga or boreal forest has been called the world’s largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States.

Detailed explanation-5: -The appearance of trees is the most noticeable visual distinction between taiga and tundra. The taiga has a dense forest of conifers such as pine and spruce, while trees are entirely absent in the tundra. This is due in part to a shortage of water in the tundra, but it is also a product of permafrost.
