Arctic vegetation is composed of plants such as dwarf shrubs, graminoids, herbs, lichens, and mosses, which all grow relatively close to the ground, forming tundra.An example of a dwarf shrub is the Bearberry.As one moves northward, the amount of warmth available for plant growth decreases considerably.
Politically, the Arctic includes the territories of the eight Arctic states (United States, Canada, Greenland, Russia, Iceland, Sweden, Norway, and Finland). By other definitions, parts of these territories would be considered sub-Arctic instead of strictly Arctic. To see the larger version of the following map, click here.
The Antarctic, therefore, meets the criteria to be considered a continent while the Arctic does not. The Antarctic is the fifth largest continent with an area of about 5.5 million square miles, but it is the least populated with about 1,000 people due to the extremely low temperature.

Were the seafloor of the Arctic Ocean to suddenly be lifted up such that the Arctic region became land, it perhaps could be a new continent named Arctica. Until such event, there is no land mass large enough to be considered an Arctic continent.
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the sun is visible at local midnight, and at least once the centre is not visible at local noon.
This ocean, called the Arctic Ocean, is like no other ocean on Earth; and because of its special location and climate, the lands that surround it are unique. Most commonly, scientists define the Arctic as the region above the Arctic Circle, an imaginary line that circles the globe at approximately 66° 34' N (dashed blue circle in the map at ...
Actually the Arctic is considered as a combination of sea ice and tundra. Antarctica is considered as a true desert, however, because it receives little annual precipitation.
The area above the Arctic Circle is underlain by sedimentary basins and continental shelves that hold enormous oil and natural gas resources. Most of this area is poorly explored for oil and natural gas; however, the United States Geological Survey estimates that the Arctic contains approximately 13 ...
The Arctic is the area around the Earth's North Pole.The Arctic includes parts of Russia, Alaska, Canada, Greenland, Lapland and Svalbard as well as the Arctic Ocean.It is an ocean, mostly covered with ice.Most scientists call the area north of the treeline Arctic. Trees will not grow when the temperatures get too cold.
The Arctic has four of the world’s 10 major fisheries, including salmon and pollock, along with a substantial amount of community-based and subsistence fishing. Access to fishing is a significant opportunity for Arctic peoples but climate change and the world’s growing appetite for fish creates new stresses on the ocean.
