The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles. These high latitudes are dominated by floating sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south.
Polar region, area around the North Pole or the South Pole. The northern polar region consists mainly of floating and pack ice, 7–10 feet (2–3 m) thick, floating on the Arctic Ocean and surrounded by land masses. The ice cap of the southern polar region averages 6,700 feet (about 2,000 m) in
Mar 1, 2023 · The Polar Regions are a crucial area of study for understanding global climate patterns and the effects of climate change on our planet. The Arctic and Antarctic regions have unique weather patterns, geological features, flora, and fauna that have adapted to survive in extreme conditions. Human settlement patterns in these areas have altered over time due to modern economic activities such as shipping, fishing, oil exploration, tourism, and scientific research in Antarctica. ...
Polar bears and arctic foxes are adapted to the extreme weather of the Arctic region. Walruses and humpback whales live in the Arctic ocean. Several kinds of penguins, including the emperor penguin , live in Antarctica, and so do walruses and narwhals .
3 days ago · Arctic, northernmost region of Earth, centered on the North Pole and characterized by distinctively polar conditions of climate, plant and animal life, and other physical features. The term is derived from the Greek word arktos (‘bear’), referring to the northern constellation of the Bear.
Nov 9, 2023 · The southern polar region, like its northern counterpart, is one of the coldest, iciest regions on Earth. Climate change is endangering both these unique places. Photograph by Cristina Mittermeier ...
Polar ecosystem, complex of living organisms in polar regions such as polar barrens and tundra. Polar barrens and tundra are found at high latitudes on land surfaces not covered by perpetual ice and snow. These areas lying beyond the tree line comprise more than 10 percent of the Earth’s land
Polar Science and Global Warming by Richard Moritz, Polar Science Center The Polar Regions. Earth has two polar regions – the Arctic and the Antarctic – and each is considerably larger than the lower 48 United States. The most distinctive features of both polar regions are cold climate and abundant snow and ice, caused by the extreme annual variation of sunlight.
Dec 7, 2023 · The polar regions of Earth are defined as the regions of the planet that surround the planet's poles, a.k.a. the North and South poles, and that lie north of the Arctic Circle, or south of the Antarctic Circle, respectively. The North Pole. The North Pole is the northernmost point on Earth. Its latitude is 90 degrees north, and all longitudinal lines meet there.
Polar regions are the coldest and most unpopulated regions on the planet, yet they are distinctive in their landscapes, climate, fauna, and flora. This defined uniqueness makes polar regions outstanding. In the north they are within an area called the Arctic Circle and in the south they are within an area called the Antarctic Convergence.
