what is the main difference between the arctic and antarctic?

The biggest difference is that the Arctic is sea surrounded by land while the Antarctic is land surrounded by sea. This fundamental difference is the reason for many of the other differences between the two regions.

Wolves and Foxes There are members of the dog family present in the Arctic. The smallest of these is the Arctic Fox, about the size of a domestic cat. ... The Arctic Wolf is long legged and pale in colour and slightly smaller than grey wolves.

The biggest factor in differences in the climate in the Northern and Southern Hemispheres has to do with the distribution of land vs. ocean. The Northern Hemisphere has much more of Earth's land masses, while the Southern Hemisphere has a larger fraction of ocean. ... First, land and ocean heat and cool at different rates.

More heat – much less ice. The atmosphere is warming as a result of increasing greenhouse gas emissions and the greenhouse effect. ... Particularly in the polar regions the rising air and water temperatures are causing fundamental changes that are occurring earlier and more noticeably in the Arctic than in the Antarctic.

Arctic air tends to be drier than polar air. Since arctic air is colder, this in turn causes the dewpoints to have to be colder. Since polar air (such as maritime polar) can develop over the oceans, it tends to have much higher dewpoints as compared to arctic air that develops over “frozen deserts”.

Arctic and Subarctic Regions. ... The arctic region sits inside the Arctic Circle and the subarctic region lies just below it. Earth's arctic and subarctic regions are extremely cold, icy areas of land and sea that receive almost no sunlight during their long, dark winters. Temperatures rarely rise above freezing.

Svalbard is cold and a dry arctic desert. Its northern location influences the amount of solar radiation it receives and is the main reason for its low temperatures. The curvature of the Earth means that the solar radiation received nearer the poles must heat a larger area than it would nearer the Equator.

The length of continuous day or night increases northward from one day on the Arctic Circle to six months at the North Pole. The Antarctic Circle is the southern counterpart of the Arctic Circle, where on any given date conditions of daylight or darkness are exactly opposite.

Polar Ice Caps We refer to the polar ice cap biome as the regions of the planet covered by ice most of the year. This includes large portions of the arctic and antarctic. ... Instead they are a mixture of carbon dioxide and water ice.

North and South America are in the Western Hemisphere. Antarctica is in both the Western & Eastern Hemispheres.

The Arctic Circle marks the region above which, for at least 1 day a year, there is all day sunshine in the summer and 24-hours of darkness in the winter. ... The line of the Arctic Circle is about 1,650 miles south of the North Pole.

As if the entire world were spinning around you. Now the Arctic Circle is easier to get to than you'd imagine. ... But the North Pole lies on top of the Arctic Ocean at a point that is constantly covered in frozen sea-ice, unlike the South Pole, which is a point of land on the continent of Antarctica.

Difference Between Hot and Cold Desert. The main difference between hot and cold desert is that the hot desert is battered by a high sun whereas the cold desert has ice and the snow in the ground. Furthermore, hot deserts are closer to the equator while cold deserts are in extreme northern or southern latitudes.

Besides location, another major difference between the two poles is that “the South Pole has Antarctica as a land mass, while the North Pole is located in the Arctic Ocean,” Urban said. ... At the North Pole, the Arctic Ocean is also very cold and has a layer of pack ice on the ocean surface.
552420
Earth's North Pole is covered by floating pack ice (sea ice) over the Arctic Ocean. Portions of the ice that do not melt seasonally can get very thick, up to 3–4 meters thick over large areas, with ridges up to 20 meters thick.

The difference between the arctic and equator environments is when the brown bunnies are present in the equator environment, the wolves eat the white bunnies and the opposite in the arctic environment. ... Brown fur only provides an advantage if the bunnies are in an equator environment.

Antarctica has no mammals that live on land. In the Arctic, several land-based mammals can be found, including reindeer, arctic fox and muskox. Both the Arctic and Antarctica have seals, birds, whales, fish, and krill. There are research stations both in the Arctic and in Antarctica.
