Why is there more ice in Antarctica than in the North Pole?

The land area of the Arctic is small, and most of it is the Arctic Ocean. Because of the large heat capacity of seawater, it can absorb more heat and dissipate heat slowly, so the annual average temperature there is about 8℃ higher than that in Antarctica. Therefore, there are fewer glaciers in the Arctic than in the Antarctic, and most of them are piled up in Greenland.

According to the investigation, the average thickness of Antarctic ice sheet is1700m, the thickest part can reach 4000m, and the total volume of glaciers is about 28 million cubic kilometers. The ice layer in the Arctic is about 2-4 meters thick, and the total volume of glaciers is only one tenth of that in the Antarctic.

The two points where the earth's rotation axis intersects the earth's surface are called "poles", the northern hemisphere is called "North Pole" and the southern hemisphere is called "South Pole". The North and South Poles are the coldest regions on the earth and the "gathering place" of glaciers. Antarctica and the North Pole are the coldest places on earth. The cold wind whistling all year round, the temperature is as low as snow and snow, and a silvery white world.

Antarctic islands:

Antarctica is divided into East Antarctica and West Antarctica. East Antarctica extends from 30 west longitude to170 east longitude, including cortese Land, Maud Land, Enderby Land, Wilkes Land, George V Coast, Victoria Land, Antarctic Plateau and Pole.

Area10180,000 square kilometers. West Antarctica lies between 50- 160 west longitude, including Antarctic Peninsula, Alexandria, Ellsworth Land and Bird Land (Mary Bird Land), covering an area of 2.29 million square kilometers. Antarctica has only some researchers and whaling teams from other continents.

Arctic islands:

The land area around the Arctic Ocean can be divided into two parts: one is Eurasia, the other is North America and Greenland, and the Bering Strait and Greenland Sea are separated between the two parts.

From the geologist's point of view, there are many similarities between these two parts of land, both of which are composed of very old large hidden crust. The age of the Arctic Ocean (oceanic crust) is much younger, and it began to appear at the end of Cretaceous 80 million years ago due to plate expansion.
