What are the 3 polar regions?

The northern polar region, called the Arctic, encompasses the Arctic Ocean and a portion of some surrounding land masses. The southern polar region, called the Antarctic, contains the continent of Antarctica and areas of the surrounding Southern Ocean.

What is called polar region?

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.

Where is sea ice found?

Sea ice occurs in both the Arctic and Antarctic. In the Northern Hemisphere, it can currently exist as far south as Bohai Bay, China (approximately 38 degrees north latitude), which is actually about 700 kilometers (435 miles) closer to the Equator than it is to the North Pole.

What is the reason for increase in Antarctic ice sheet?

The general trend shows that a warming climate in the southern hemisphere would transport more moisture to Antarctica, causing the interior ice sheets to grow, while calving events along the coast will increase, causing these areas to shrink.

Who named the Arctic?

Before Antarctica officially acquired its name, the phrase was used to describe places that contrasted the north. For instance, in the 16th century, the colony that was built by the French was named France Antarctique, and Scottish cartographer John George Bartholomew used it officially around the 1890’s.

What is North Pole called?

Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight.

Where is the polar zone?

The polar zone encompasses the areas around the North and South Poles. Starting from the North Pole, this zone stretches to the Arctic Circle in the Northern Hemisphere, and reaches even further south in North America and Asia.

What are the three types of sea ice?

It may rapidly form over wide areas of water. Brash Ice: Accumulation of floating ice made up of fragments not more than 2 m across, the wreckage of other forms of ice. Ice Cake: Any relatively flat piece of ice less than 20 m across. Floe: Any relatively flat piece of ice 20 m or more across.

How sea ice is formed?

Sea ice is formed when ocean water is cooled below its freezing temperature of approximately -2°C or 29°F. Such ice extends on a seasonal basis over great areas of the ocean.
