Arctic. The Arctic is a polar region located at the northernmost part of Earth.
The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska, Finland, Greenland, Iceland, Northern Canada, Norway, Russia and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost containing tundra.
Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems.
For example, the cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies.
Arctic land is bordered by the subarctic. The word Arctic comes from the Greek word, near the Bear, northern and that from the word, meaning bear. The name refers either to the constellation Ursa Major, the Great Bear, which is prominent in the northern portion of the celestial sphere, or to the constellation Ursa Minor, the Little Bear, which contains Polaris, the Pole star, also known as the North Star. There are a number of definitions of what area is contained within the Arctic. The area can be defined as north of the Arctic Circle, the approximate southern limit of the midnight sun and the polar night. Another definition of the Arctic
