There are no countries on the Antarctic continent.
Inhabited settlements within the Arctic Circle include those on the coast of the northern two thirds of Greenland, portions of Norway Sweden, and Finland, the major city of Murmansk and a few Siberian towns in Russia, Kotzebue, Fort Yukon, and Barrow in Alaska, and several towns in northern Canada. Except for scientific research stations, there are no permanent population centers within the Antarctic Circle.
Tropic of Capricorn and Antarctic Circle
Erebus lies on the Antarctic continent, where there are no countries.
You could call them mirror opposites, identifying the same phenomenon in two polar regions.
into east and west
The Antarctic Convergence is a circle which encircles the area, and is very high in marine productivity. It separates two climates and various marine life.
The South Temperate and South Polar Zones
There is no country in the Arctic Circle. There are , however, countries partially in the Arctic circle like Norway.
Technically, both polar regions -- above the Arctic Circle and below the Antarctic Circle -- are equal. However, Antarctica occupies the larger landmass, of the two, covering about 10% of the earth's surface.
You're thinking of the Weddell Sea and the Ross Sea.
In regions between the Tropic of Cancer and the Antarctic Circle and between the Tropic of Capricorn and the Antarctic Circle, there are typically only two seasons: a wet season and a dry season. The proximity to the equator limits the variation in temperature, resulting in predominantly wet and dry climatic conditions.
