What are the two white hats of the earth?
In addition, "White Hat" is a treasure house of natural resources, which contains mineral resources such as oil and natural gas. In addition, most of the fresh water on the earth is stored in two "white hats" in the form of ice, and some ice has existed for hundreds of thousands of years.
The South Pole and the North Pole are the areas south of the guiding latitude 66 degrees 34 minutes and north of the guiding latitude 66 degrees 34 minutes respectively. Both of them have the same area, which is 2 1 10,000 square kilometers.
The sea area of the Arctic is almost the same as that of the Antarctic continent, the former is 13 10 square kilometers, and the latter is 1362 square kilometers. The deepest depth of the Arctic sea area is almost the same as the height of the highest peak of the Antarctic continent, which is 54 19 km and 5 140 km respectively.
Extended data:
Winter in the Arctic Ocean lasts for six months from June 1 1 to April of the following year. May-June and 9- 10 belong to spring and autumn. In summer, it only lasts for seven or eight months. The average temperature in June+10/October in 5438 was between-20 and-40℃.
The average temperature in August, the warmest month, is only about MINUS 3 degrees Celsius. The lowest temperature measured at the drifting station near the pole of the Arctic Ocean is -59℃. Due to the influence of ocean current, Arctic anticyclone and land-sea distribution, the coldest place in the Arctic is not in the middle of the Arctic Ocean.
The lowest temperature of -70℃ was recorded in Yansk and Oymyakon in Vilho, Siberia, and the lowest temperature of -63℃ was also recorded in yukon river, Alaska.
In the arctic ice and snow, there are still quite large oases. In this oasis, there are not only higher plants, but also large forests.
The North Atlantic Warm Current transports warm water at lower latitude (south of 50 degrees north latitude) from south to north along the Norwegian Sea until it reaches about 80 degrees north latitude.
According to the calculation of marine climatologists, the North Atlantic warm current transported from south to north can raise the atmospheric temperature over Norwegian waters by about 20 degrees Celsius every year. Judging from the average surface temperature in the northern hemisphere for many years, the annual average temperature along Scandinavia and Svalbard is 5-20 degrees Celsius higher than that in other areas at the same latitude.
