Everything about Polar Climate totally explained
Regions with a
polar climate are characterized by a lack of warm summers (specifically, no month having an average temperature of 10 °C or higher).
The tundra covers over 20% of the earth. The sun shines 24 hours in the summer, and barely shines at all in the winter (see
midnight sun).
Effects
Polar climates result in the absence of
trees in such places, which may also be covered with
glaciers or a permanent or semi-permanent layer of
ice. and they also get thier food from fishes
Examples
On Earth, the only continent where the extreme (
EF -- ice cap) polar climate is predominant is
Antarctica. All but a few isolated coastal areas on the island of
Greenland also have the extreme
EF polar climate. Such coastal regions of Antarctica and Greenland that don't have permanent ice sheets have "only" the less extreme tundra (
ET) climates.
The northernmost part of the Eurasian land mass, from the extreme northeastern coast of
Scandinavia and eastwards to the
Bering Strait, large areas of northern
Siberia and Northern
Iceland have tundra climate as well. Large areas in northern
Canada and northern
Alaska have tundra climate, changing to ice cap climate in the most northern parts of Canada. Southernmost South America (
Tierra del Fuego where it abuts the
Drake Passage and such subantarctic islands such as the
South Shetland Islands and the
Falkland Islands have
ET, or tundra climates of slight thermal range in which no month is as warm as 10°C. These subantarctic lowlands are to be found more equatorward than the coastal tundras of the Arctic basin.
In other parts of the world, many
mountains have a climate where no month having an average temperature of 10 °C or higher, but as this is due to elevation, this climate is referred to as
Alpine climate. Polar climates have also been observed on other planets, such as
Mars, which has noticeable ice caps on both poles.
