Did you know that the Earth has a 4-pole, two geographic and two magnetic?And the geographic poles do not coincide with the magnetic.Do you want to know where the Earth's magnetic poles?At the end of the twentieth century under the name they were: the North - in the depths of the northern coast of Canada and the south - about a hundred kilometers from the edge of Antarctica.
And where are the magnetic poles of the earth now?They constantly moving.For example, north in 1831 (at the time of its opening), it was at 70 degrees.w.In Canada.After 70 years of polar explorer R. Amundsen found him already at 50 km to the north.Scientists are interested in this, and began to watch.It turned out, the pole "traveled" with increasing speed.Initially, its speed was low, and in recent years has grown to 40 km / year.At this rate, by 2050, the north magnetic pole "register" in Russia.And it will not just beautiful pictures of the northern lights, which will be seen almost the whole of Siberia, but also problems in the use of the compass.Also, increase the level of exposure to cosmic rays, t. To. Near the poles of Earth's magnetic field is much smaller than at the equator.The measurements showed that in the 150 years of Earth's magnetic field has decreased by 10%.And it is a very effective means of protecting all life from the hard solar and cosmic radiation.American astronauts who flew to the moon, come out from the cover of Earth's magnetic field and got a mild form of radiation sickness.And even as they did not see the moon, but to see where the Earth's magnetic poles, they could not.
Land on the Antarctic
Antarctica - a part of the Earth's near the South Pole.It was called "anti-Arctic" or Ant-Arctic, as an antagonist of the Arctic.The name comes from the last Greek Arktos - Dipper.Since the ancient Greeks called the constellation Ursa Minor with the Polar Star, known to all travelers.
Antarctica consists of the mainland of Antarctica, its adjacent parts of the Atlantic, Pacific and Indian oceans and seas of Bellingshausen, Russia, the Commonwealth of the Weddell, Amundsen and others. All of Antarctic Marine named the Southern Ocean.In the Antarctic and includes the South Shetland Islands, South George, South Orkney, South Sandwich and many others.. Thus, Antarctica takes around 50-60 minutes southern parallels.
Antarctica - the most, the most ...
Antarctica - the biggest and driest desert - the level of precipitation is less than 100 mm per year, from 40-50 mm at the center to 600 mm in the north of the Antarctic Peninsula.The best known in the narrow circles of the Dry Valleys.Rains are not seen two million years.Neighbor Dry Valleys - the Atacama Desert, where the rain was not just 400 years.The lakes of this valley - the most salty in the world.Dead Sea compared to them - almost fresh.
Antarctica - the harsh climate, the minimum temperature recorded on Earth at the Soviet Antarctic station "Vostok" July 21, 1983 - minus 89,6 ° C.
Antarctica - a place the strongest winds.Dashing glory are katabatic winds.The air is in contact with the glacier at an altitude of 1,000 to 4,500 meters cools, condenses and starts accelerating flock to the coast, sometimes reaching speeds of 320 km / h.
Antarctica - the icy parts of the earth.Only 0.2-0.3% of its surface is covered by ice - in the Transantarctic Mountains and the western part of the continent, as well as coastal areas or individual ridges and peaks (nunataks).
summer south of the Arctic Circle, these areas are heated strongly, and then heats the air above them.For example, in the Dry Valleys of Victoria Land in December 1961 was 23.9 ° C +
Now you know where the Earth's magnetic poles.
