  2. Tundra - Wikipedia

    en.wikipedia.org/wiki/Tundra

    In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) 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, [2] Alpine, [2] and Antarctic. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens ...

  3. Tundra of North America - Wikipedia

    en.wikipedia.org/wiki/Tundra_of_North_America

    The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...

  4. Tundra climate - Wikipedia

    en.wikipedia.org/wiki/Tundra_climate

    The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification . It is a climate which at least one month has an average temperature high enough to melt snow (0 °C [32 °F]), but no month with an average temperature in excess of 10 °C (50 °F ...

  5. Alpine tundra - Wikipedia

    en.wikipedia.org/wiki/Alpine_tundra

    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 elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .

  6. Biome - Wikipedia

    en.wikipedia.org/wiki/Biome

    A shift of 1 or 100% (darker colours) indicates that the region has fully moved into a completely different biome zone type. [46] Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [47] [48] Climate change represents long-term changes in temperature and average weather patterns.

  7. Köppen climate classification - Wikipedia

    en.wikipedia.org/wiki/Köppen_climate_classification

    Tundra climate (ET): warmest month has an average temperature between 0 °C (32 °F) and 10 °C (50 °F). These climates occur on the northern edges of the North American and Eurasian land masses (generally north of 70 °N although they may be found farther south depending on local conditions), and on nearby islands.

  8. Ice cap climate - Wikipedia

    en.wikipedia.org/wiki/Ice_cap_climate

    Ice cap climate is the world's coldest climate, and includes the coldest places on Earth. With an average temperature of −55.2 °C (−67.4 °F), Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, −89.2 °C (−128.6 °F). [3] The following chart indicates the average and record temperatures ...

  9. Polar climate - Wikipedia

    en.wikipedia.org/wiki/Polar_climate

    A tundra climate is characterized by having at least one month whose average temperature is above 0 °C (32 °F), while an ice cap climate has no months averaging above 0 °C (32 °F). [2] In a tundra climate, even coniferous trees cannot grow, but other specialized plants such as the arctic poppy can grow. In an ice cap climate, no plants can ...
