  2. Ocean temperature - Wikipedia

    en.wikipedia.org/wiki/Ocean_temperature

    Not only does the temperature differ in seawater, so does the salinity. Warm surface water is generally saltier than the cooler deep or polar waters. [1] In polar regions, the upper layers of ocean water are cold and fresh. [2] Deep ocean water is cold, salty water found deep below the surface of Earth's oceans.

  3. Polar regions of Earth - Wikipedia

    en.wikipedia.org/wiki/Polar_regions_of_Earth

    Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. 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.

  4. Sea ice - Wikipedia

    en.wikipedia.org/wiki/Sea_ice

    [1] [2] [3] Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ...

    Quizlet is a multi-national American company that provides tools for studying and learning. [1] Quizlet was founded in October 2005 by Andrew Sutherland, who at the time was a 15-year old student, [ 2 ] and released to the public in January 2007. [ 3 ]

  6. Polar climate - Wikipedia

    en.wikipedia.org/wiki/Polar_climate

    Solar radiation has a lower intensity in polar regions because the angle at which it hits the earth is not as direct as at the equator. Another effect is that sunlight has to go through more atmosphere to reach the ground. [1] The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month a polar ...

  7. Antarctic Convergence - Wikipedia

    en.wikipedia.org/wiki/Antarctic_Convergence

    [4] Although this zone is a mobile one, it usually does not stray more than half a degree of latitude from its mean position. The precise location at any given place and time is made evident by the sudden drop in seawater temperature from north to south of, on average, 2.8 °C (5.0 °F) from 5.6 °C (42.1 °F) to below 2 °C (36 °F).

  8. Polar seas - Wikipedia

    en.wikipedia.org/wiki/Polar_seas

    Polar bear in Manitoba, Canada. November 2004. Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans). In the coldest years, sea ice can cover around 13 percent of the Earth's total surface at its ...

  9. Polar ecology - Wikipedia

    en.wikipedia.org/wiki/Polar_ecology

    Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere , and it contains land and the islands that surrounds it.
