Do you know where are the magnetic poles of the earth

Did you know that the Earth has 4 poles: two geographic and two magnetic? And geographical poles do not coincide with magnetic poles. Do you want to know where are the magnetic Pole of the Earth? In the late twentieth century, according to the names, they were: the northern one - in the depths of the northern coast of Canada, and the southern one - a hundred kilometers from the edge of Antarctica.

And where are the magnetic poles of the earth now? They Constantly move. For example, the northern one in 1831 (at the time of its discovery) was at 70 ° N. W. In Canada. After 70 years, the polar explorer R. Amundsen found it already 50 km to the north. Scientists became interested in this and began to follow. It turned out that the pole "travels" with increasing speed. At first, its speed was small, and in recent years has grown to 40 km / year. At such rates, by 2050 the northern magnetic pole will be "registered" in Russia. And this will bring not only beautiful pictures of the northern lights, which will become visible almost throughout Siberia, but also problems in using the compass. Also, the level of exposure to space And rays, since near the poles the Earth's magnetic field is much smaller than that of the equator. Measurements have shown that over 150 years the Earth's magnetic field has become smaller by 10%. And it is a very effective means of protecting all life from hard solar and cosmic radiation. American astronauts, flying to the moon, came out from under the cover of the Earth's magnetic field and received an easy form of radiation sickness. And as they did not look from the Moon, they could not see where the magnetic poles of the Earth were.

Earth in the Antarctic

Antarctica is part of the Earth near the South Pole. It was called "Anti-Arctic" or Ant-Arctic, as an antagonist of the Arctic. The name of the latter came from ancient Greek arctos - Medveditsa. So the ancient Greeks called the constellation of the Little Dipper with the Polar Star, known to all travelers.

Antarctica consists of the continent of Antarctica, the adjacent parts of the Atlantic, Pacific and Indian oceans and the seas of Bellingshausen, Ross, the Commonwealth, Weddell, Amundsen, and others. All the marine parts of the Antarctic are called the Southern Ocean. The Antarctic includes the islands of South Shetland, South Georgia, South Orkney, South Sandwich and many others. Etc. Thus, Antarctica occupies the area of the 50-60th southern parallels.

Antarctica is the most, the most, the most ...

Antarctica is the largest and dryest desert - the level of precipitation is less than 100 mm per year: from 40-50 mm in the center to 600 mm in the north of the Antarctic Peninsula. The Dry Valleys are the most famous in narrow circles. The rains here have not been seen 2,000,000 years. The neighbor of the Dry Valleys is the Atacama Desert, where rain was not only 400 years old. The lakes of this valley are the most saline in the world. The dead sea in comparison with them - almost fresh.

Antarctica is the harshest in the climate, the lowest temperature on Earth recorded at the Soviet Antarctic station "Vostok" on July 21, 1983 - minus 89.6 ° C.

Antarctica is the place of the strongest winds. Distant fame is katabatic winds. Air in contact with glaciers at an altitude of 1000 to 4500 m cools, thickens and begins to accelerate, to flow to the shore, sometimes reaching a speed of 320 km / h.

Antarctica is the most icy place on Earth. Only 0.2-0.3% of its surface is not covered by ice - in the Transantarctic mountains and the western part of the continent, as well as parts of the coast or individual crests and peaks (nunataks).

In the summer to the south of the polar circle these areas become very warm, and then the air above them is heated. For example, in the Dry Valley on Victoria Land in December 1961, there was + 23.9 ° C.

Now you also learned where the magnetic poles of the Earth are.
