The glaciers in the Arctic are only one tenth of those in the Antarctic.

The glaciers in the Arctic are only one tenth of those in the Antarctic.

The South Pole and the North Pole are the coldest places on the earth, where the cold wind whistling all the year round is a silvery white world. However, compared with the two places, the weather in Antarctica is colder than that in the North Pole, and there is much more ice in the glacial state all the year round than that in the North Pole. The average annual temperature in the central Antarctic continent is only -56℃, and the lowest temperature has reached -88.3℃. The average temperature in Leng Yue (July) is -70℃-20℃. The average temperature in the warmest month (65438+ 10) is also below 0℃, making it the coldest land in the world.

However, the average temperature in Leng Yue (65438+1October) in the Arctic sea area is -40℃-20℃, and July-August is a warm season, with the average temperature mostly below 8℃. The climate in the middle of the Arctic Ocean is milder than that at the edge. The coldest areas are in the lower reaches of the Lena River in Siberia and the central part of Greenland. The lowest temperature of Vilho Jansk is -68℃.

According to the investigation, the average thickness of Antarctic ice is about 1700 meters, the thickest part is more than 4000 meters, and the total volume of glaciers is about 28 million cubic kilometers, which is called "the world of ice and snow". In the Arctic, the distribution area of glaciers is much smaller than that in the Antarctic, and the thickness is generally about 2-4 meters. The total volume of glaciers is only about110 of the Antarctic.

Both the South Pole and the North Pole are located at the two poles of the earth, with the same latitude and the same length and angle of the sun. So, why is there more ice in Antarctica than in the North Pole?

It turns out that there is a large piece of land in the Antarctic region, which is known as the "seventh continent" in the world, with an area of about 6,543,800 square kilometers. The heat storage capacity of the land is not strong, and the heat gained in summer is quickly dissipated, so there is more ice. Continental glaciers move in all directions from high places, breaking into many huge ice cubes at the seaside and floating on the ocean around the mainland, forming tall ice barriers and icebergs.

The Arctic Ocean covers a large area, about 1, 365438+ 10,000 square kilometers. Water has a large heat capacity, which can absorb more heat and then dissipate it slowly, so there is less ice than the Antarctic, and most of the ice is accumulated in Greenland.
