10 FACTS AND MISCONCEPTIONS ABOUT THE MODERN WORLD NICHOLAS KHIZHNYAK NIODIX ID191473620 september 26, 2014 at 18:30 7835 views 4 comments About the Author earth Since the first person in the history of space exploration rose into space and saw the vast expanses of our blue ball, people literally swept maniacal idea to find out absolutely all the mysteries of our planet. In the world there are many interesting and unusual. But sometimes it happens that some of the new things that we know we are not perceived as they really are. So there are errors. Please find a selection of 10 interesting facts and misconceptions about the Earth. Mount Everest is growing in breadth, and not upwards everest About fifty million years ago the Indian subcontinent “decided” that he was tired of being in the neighborhood of the southern part of the equator, and he began his movement in the Indian Ocean to the north. As a result of the subcontinent collided with Asia. This is how the Himalayan mountain range, including Mount Everest. Today the height of the mountain is about 9 kilometers and it is recognized as the highest mountain on Earth, located above sea level. Collision of India and Asia is still going on, and therefore should continue to increase in the mountains, right? Wrong, say the researchers, to conduct a careful measurement of the height of the mountain. Geordie Poretti, professor at the University of Trieste (Trieste – a city in northern Italy), back in 1995 found that Mount Everest is not growing up, as previously thought. The difference in the size of its effect rather as measurements, whose level of accuracy is certainly improved over the years. Poretti said that the ongoing continental collision between India and Asia actually makes Everest move to the north-east, about 42 millimeters per year. So when the next conqueror of mountains climb Mount Everest, as in 1953, first made by Sir Edmund Hillary and Tenzing Norgay, then he shall come up to the same height as the pioneers, only about 3 meters north-east of the point in space , where it was first recorded ascent of this record. The highest mountain in the world is Mauna Loa loa Speaking of Everest – the mountain is not the highest in the world in absolute terms. Mauna Loa (which translates from the Hawaiian “Long Mountain”) is part of the island of Hawaii and in combination – megavulkanom. Of course, visually Mauna Loa even close to matching the height of Mount Everest, but it’s only because most of the mountains sunk deep and we can only observe its top. Scientists estimate that from the bottom to the top of the true height of Mauna Loa is slightly more than 10.2 kilometers, which makes it much higher than Everest. An important role is played in the calculations and weight mountains, it is much greater than that of Mount Everest. The fact that Mauna Loa takes up almost half of the island of Hawaii. As already noted, this mountain is a volcano, and the volcanoes of this size are usually called “shields” – due to the fact that they are spread over a very large plane, and thus have a low profile, in general, like a shield. Such volcanoes formed as a result of repeated outpourings of lava. Molten lava breaks out of Mauna Loa so quickly that she had no choice but to quickly settle and cool, thereby increasing the area of ​​the volcano. Mauna Loa erupted frequently, and many of these eruptions lasted for millions of years. As a result, Mauna Loa is the largest active volcano and the underwater world – its volume (including the underwater part) is more than 80 000 cubic kilometers. The depth of the Pacific Ocean at the point where the Mauna Loa began erupting for the first time is about 5 kilometers. For many millions of years has erupted lava created a mountain that rose out of the water and now stands at 4.17 km above sea level, and at the same time and is for the most part of the island of Hawaii. But that’s not all. The fact that a huge weight Mauna Loa eventually made the ocean floor to fall (tamped) for a further 8 kilometers below. Having taken heed of this fact, it is clear that the total height of the volcano is more than 17 kilometers, which makes Everest look like next to him as a small rocky gorochku. Tornado invisible tornado With the threat of tornadoes will be the best way to find yourself some solid underground shelter. However, the issue here stands in the way in which we can see a tornado, because the air is invisible? In fact, from a technical point of view, we see not just the air and condensing cloud of water droplets, as well as dirt and debris. Formed a tornado funnel from the invisible air, which eventually grows and sucks in everything that comes its way. Typically, tornadoes are formed in the supercell – giant storm clouds having both incredibly beautiful shape and destructive force. Scientists still can not confidently and accurately explain what causes a vortex to move down from the supercell to the ground. Perhaps the root cause here are the temperature differences on the edges of the wind flows. Observations scientists show that the water vapor normally condenses inside the rotating funnel of air, which is formed from supercell, but tornadoes can form a vortex on the ground long before they form a funnel that. For example, the picture above shows a tornado only with partially formed funnel cloud. If this was a whirlwind around you and still not managed to gather denouncing his views rubbish, the consequences would have been disastrous. Would you just did not see it. Clouds weigh a ton clouds The phrase “light as a cloud,” the next time compliment your sweetheart now will seem quite out of place. We all tend to think that the cloud – it is not nothing but a bunch of fog, or something like that. However, clouds are incredibly heavy. Average cumulus cloud is composed of water droplets and weighs 550 metric tons (500 tons). Such a “hippopotamus” can soar just because the atmosphere around it weighs more. Cumulus clouds are in the lower atmosphere. Air molecules herein have a weight of 1 kilogram per square centimeter. The average surface area of ​​the human body is 12-15 thousand square centimeters and as a result of the calculations, it is clear that the air pressure on it will be about 15 tons. Why do we not flatten? The fact that the external air pressure is balanced by the pressure inside it of the body. Moreover, the air flowing the same as water. Here comes into play the law of Archimedes – the buoyancy acting on the cloud, it is equivalent to the weight of the ejector air. In other words, multi-ton clouds hover in the air for the same reason that the ships can float on water. On Earth, there are magnetic tornado magnetic-storm NASA’s aerospace experts were surprised when the spacecraft Messenger, circling around Mercury, found inside the magnetic field of the planet “tornado” in diameter more than 800 kilometers. These transport phenomena of magnetic fluxes, or “plasmoids”, formed when Mercury’s magnetic field collides with the magnetic field of the Sun. Scientists believe that this fact is a consequence of such a thin atmosphere of Mercury, the way it has. From the solar wind (plasma ejected by the Sun) is formed crater, which falls on the surface of Mercury, where, thanks to the electrically charged particles released from the soil residual gases. Scientists have long been aware of the fact that the magnetic field of the Earth and the Sun are related. As a result of this connection, for example, formed the northern lights. What they did not know before the opening associated with Mercury, is the fact that this relationship is so turbulent. Inhabitants of the earth, however, do not worry. Despite the fact that these events occur every eight minutes, the atmosphere of our planet is so thick that protects us from deadly cosmic radiation fluxes. In the rocks there is life endo Certainly, even in the desert or deep cave, a man once felt as if he is in this place is not one. And it really is true. The fact that within a seemingly ordinary stones can boil a stormy life. They can live a very tiny creatures that bear the name “endolithic”. Endolithic belong to the group esktremofilov. In other words, they like to live in extreme conditions. They were found at a depth of almost 3 kilometers underground. Most of endolithic can live without food and water, which can fall into the rocky fissures. However, some species feed on endolithic stones. To do this, they secrete an acid that dissolves their future rocky breakfast. As you know, one of the limiting factors of how deeply life can penetrate inside our planet is the temperature. Penetrate deeper into the earth, the hotter it becomes the surroundings. So, at a depth of 5 kilometers the temperature rises to 125 degrees Celsius. As long as any scientist could not reach so deep, but the study of extremophiles that live in hot springs, found that when they are in similar conditions with the temperature at the extremophiles manifest problems with their reproductive functions. In other words, it is likely that 5 kilometers deep is their absolute maximum. Since the discovery of endolithic astrobiology experiments carried out underground, whose task is to identify the possible existence of life in outer space. Indeed, there have been known, too extreme conditions. Level of Switzerland on the map height increases and decreases by almost 25 centimeters every day switzerland Earth, it turns out, is not only an attractive place for many species of living organisms. The fact that the planet surface is very elastic. For the same reason the volcano Mauna Loa pushing Pacific surface for a few kilometers inland. This flexibility can also say that the Moon and the Sun can affect the surface in the same way as they affect the water, though not as pronounced. Watch the tides for us is easy. Much more difficult to observe as huge portions of the surface of our Earth is beginning to rise, on the contrary, fall – it happens very slowly. Do you think that this rule applies only to the plains and those places where there is no super-giant volcanoes and mountains? You are mistaken. Compared to the strength of the Moon and the Sun even Alps powerless. Very thorough scientific study and measurements have shown that all of Switzerland that rises every day, it falls on the earth’s firmament of about 25 centimeters. Cyclones can “dance” cyclone Tornadoes sometimes called cyclones, but from a technical point of view cyclones – are huge vortices (diameter can reach tens of thousands of kilometers) from the center of low pressure in their air, where the air circulates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. In cyclones may develop into hurricanes and any eddy currents with low pressure. Japanese meteorologist Sakuhei Fujiwara was the first who found that when the distance between two cyclones they start to spin or dance around the center of convergence. This observation has been called Fujiwara effect. This effect can occur only if the relative strength of both cyclones equal, otherwise a larger size cyclone simply absorb finer. In 2012, the world witnessed a devastating from all points of view an example of this phenomenon. Most hurricanes in the Caribbean Sea and the Atlantic Ocean eventually picked up by the westerly winds, which is distilled from these storms in North America. To some extent this was the case with Hurricane Sandy. However, he suddenly changed direction and returned to the United States and Canada, and due to the increased concentration of low pressure near it grew into a heavy duty cyclone. His wind flows steel rotate in the same direction, giving rise to the effect Fujiwara, who made Caribbean hurricane back. Due to the fact that Sandy was a big in size, both storms merged into one Supershtorm, right over the land, which was the worst case of such events. Giant earthquakes occur slowly and almost imperceptibly earthquake Earthquakes occur due to movement of rocks along faults. These faults can be a local form (in this case, the earthquake is likely to also be wearing only a local character), and large-scale – between two tectonic plates. As a result of this movement accumulates a huge amount of energy in the form of elastic tension breeds, and when this voltage reaches a critical point, the abrupt discontinuity and displacement of these species, which in turn causes the oscillation wave surface. Before many large earthquakes occur preliminary tremors, but researchers were surprised to find that the friction between the rock and can occur even without any shocks. They managed to find out after installation ultrasensitive equipment along the San Andreas Fault in California (a rift between the Pacific and North American tectonic plates), as well as the Alpine Fault, where in the past there were a very large earthquake, but the central point of which was always surprisingly quiet. Scientists have begun to closely monitor this region and first suggested that there continues to accumulate potentially catastrophic for the whole region energy level. But instead they found seismic vibrations – a series of subtle (but very long in comparison with the conventional earthquakes) so-called creeping earthquakes (very slow offset rupture), lasting up to 30 minutes each. Something similar has been found in some parts of the San Andreas Fault. Scientists are not quite sure what accounts for these fluctuations. Perhaps as a result of accumulated stress for future earthquakes, or vice versa, as a result of such subtle tremors releases the excess energy, which subsequently reduces the intensity of earthquakes that may occur in the future as a result of further displacement of the plates. Next eruption supervolcano, likely will not be associated with the Yellowstone supervolcano Yellowstone Park is a very attractive place for tourists. Geysers, hot springs, boiling mud pots are very interesting for nature lovers. But the peak of popularity of this area occurred at the turn of the 21st century, when geologists discovered that in the world there are so-called supervolcanoes and Yellowstone volcano is just one of these. From that moment on, many have begun to wonder when it will happen eruption. But it turns out that this is unlikely to happen at some point in time, at least within the framework of human civilization. Recent studies have shown that despite the fact that the volcano has really huge amount of magma, it contains is not in the eruptive form (ie can not erupt). In the history of man has never witnessed the eruption of the super, so no one still does not know what will be the signs of the eruption. It is very likely that before the main eruption will occur a series of earthquakes and other destructive natural phenomena. In the end, ordinary volcanoes can erupt quite suddenly, so no one cancels the possibility that supervolcanoes are able to do so unpleasant and unexpected surprises. Perhaps one of the most interesting candidates for the eruption of a supervolcano may be Chilean Laguna del Maul, although at present no signs of eruption, he does not show. The only thing that is strange, mysterious and, therefore, of interest to scientists is the fact that the volcano increases in size by about 24-28 centimeters per year. And no one knows why. Laguna del Maul is located on the Argentine border and the size is approximately equal to the volcano Long Valley, which is located in California. Over the past more than 20 000 years there were at least 36 mini-eruptions of this volcano. The scientists who conducted the research, said that they found it a sufficient number of eruptive magma that this volcano could get at least a classification of VEI 6 (a measure of strength of the eruption of the volcano). This level can not be called supervulkanicheskim (he probably equal to the eruption of Mount Pinatubo in the Philippines that occurred in 1991), but scientists still are not sure whether all this magma that this volcano while hiding.

But that’s not all. The fact that a huge weight Mauna Loa eventually made the ocean floor to fall (tamped) for a further 8 kilometers below.
