hat are the Types of Tundra Biome?
Extremely cold temperatures and frozen, treeless landscapes characterize the tundra biome. While some sources claim that the word ‘tundra’ originates from the Kildin Sami term ‘tundar’, which means ‘treeless mountain track’ or ‘uplands’, others say that it has been derived from the Finnish ‘tunturia’, meaning ‘barren land’. The tundra is divided into two types: The Arctic Tundra, which is also present in Antarctica, and Alpine Tundra. The ecological boundary region, or ecotone, which demarcates the tundra and the growth of forest, is referred to as the timberline or tree line.
