The Arctic
is a very cold, windy, and often snowy biome located around the North
Pole. When referring to the Arctic, people usually mean the part of
the earth within the Arctic Circle (an imaginary circle around the Earth,
parallel to the Equator and 23 degrees 28 minutes from the North Pole,
that is, above about 75 degrees North Latitude). Although there is no
land at the North Pole, the icy Arctic Ocean is teeming with life ranging
from the microscopic (like zooplankton) to the huge (like whales).
There is also a lot of land within the Arctic Circle
(northern parts of Asia, Europe, and North America). Land within the
Arctic Circle is tundra , and it supports less life most other biomes
because of the cold temperatures, strong, dry winds, and permafrost
(permanently-frozen soil). Long periods of darkness (in the winter)
and light (in the summer) also affect Arctic life.
Arctic Land Zones:
The most extreme Arctic land (the closest to the North Pole) is called
the High Arctic Zone ; this polar desert supports very little animal
or plant life (less than 5 percent of the land area is covered with
vegetation) due to a very short, dry growing season, dry air, permafrost,
poor soils, and a lack of pollinating insects. The warmer Arctic region
is called the Low Arctic Zone. This area supports more life, with more
than 90 percent of the land area covered with hardy, cold-and-dry-adapted
vegetation.
