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: -The boreal forest (or “taiga”) is the world’s largest land biome. The boreal ecozone principally spans 8 countries: Canada, China, Finland, Japan, Norway, Russia, Sweden and the United States.

Detailed explanation-3: -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-4: -A temperate forest is a forest found between the tropical and boreal regions, located in the temperate zone. It is the second largest biome on our planet, covering 25% of the world’s forest area, only behind the boreal forest, which covers about 33%.
