Abstract from DBPedia
    The Arctic (/ˈɑːrtɪk/ or /ˈɑːrktɪk/) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic.

    北極(ほっきょく、英: Arctic)とは、地球などの惑星・天体の地軸と地表が交わる点のうち、北側のものである北極点の周辺地域、もしくは北極点そのものを指す。地球上では北極海などを含む地域で、特に白夜・極夜の見られる区域を北極圏と呼ぶ。 地球の自転軸上の北極点と方位磁石が示す北極である北磁極は異なる場所にあり、1000km程離れている。そのため、方位磁石が示す方向が必ずしも真北とは限らない。南北の磁極は移動し続けている。
