Tundra. In physical geography, tundra (/ ˈtʌndrə, ˈtʊn -/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3]
The Tundra of North America is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation ...
Alpine tundra. Hikers traversing the Franconia Ridge in the White Mountains of New Hampshire, much of which is in the alpine zone. Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold ...
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (0 °C or 32 °F), but no month with an average temperature in excess of 10 °C (50 °F). [1]
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
Terrestrial ecosystems are ecosystems that are found on land. Examples include tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, deserts. [1] Terrestrial ecosystems differ from aquatic ecosystems by the predominant presence of soil rather than water at the surface and by the extension of plants above this soil/water ...

July 20, 1975. Pingos are intrapermafrost ice-cored hills, 3–70 m (10–230 ft) high and 30–1,000 m (98–3,281 ft) in diameter. [1] They are typically conical in shape and grow and persist only in permafrost environments, such as the Arctic and subarctic. [2] A pingo is a periglacial landform, which is defined as a non-glacial landform or ...
