Geomagnetic reversals Introduction The geomagnetic field of Earth is continuously going througha reversal. We as Homo sapiens don’t know that when these reversals will be completed, it is expected to continue in the future as well. Many scientists today have begun to worry that this magnetic pole is the primary reason behind the climatic change in the world. This field is constantly being harmed by deep space and sun. These reversals are causing earthquakes in the Earth crest or creating volcanoes on the Earth’s surface. This climate and Earth change are not man-made pollution of the air; it is also not by global warming or the sun, but by the volcanic activity under the Earth which is causing the oceans to boil up. The gradual shifting of the pole is believed to have been the reason for destruction of entire human civilizations. As this reversal takes place, the earthquakes augment and earthquake storms take place in the world. Furthermore, three new volcanoes are born at many places in the Pacific Ocean. NASA has recently found out that there is a break in the magnetic field of the Earth. These changes keep on building and concurrent. (Syzygyastro) The constant changes that go inside the surface of the Earth cause this reversal. The core of the Earth moves around a little faster than the crust of the Earth which is slowed by tidal dragging of the moon. The disparity in the rotation between the two layers produces the magnetic field. When the core rotates, the lines of magnetic field act as what takes place on the Sun’s surface as equator and sun have different rotations from the pole. The disparity of rotation of both of these surfaces creates a stretch in the lines of magnetic field so they wrap round and round the Earth or the sun. What happens is that magnetic field lines the field and recreates itself. The discrepancy of the rotation of Sun happens at a faster rate than the Earth so the magnetic cycle on average takes around 22 years in the Sun. The Earth takes a very long time for its periodic cycle due to the interaction of the sun, planets, and the moon and slower winding. These reversals of the field can take millions of years to take place. At present, Earth’s field lines are constantly breaking down, making a complicated pattern of hundreds of magnetic zones similar to the ones on the Sun. This violation in the earth/s magnetic allows the solar winds to go to the atmosphere of Earth. The consequence of these modifications will be auroras all across the Earth even at the equator. The second alteration is the diffusion to the Earth surface from the space and the sun. This radiation also causes the clouds to form and rainfall augments in the areas where magnetic field is most neutral or weakest. As the field changes its course slowly, the weather patterns change at the same rate. (Syzygyastro) The above figure shows the data that National GeoPhysical Data Center keeps up when the yearly North Pole communicates, driven from the earliest measurements from the logos of ships in 1690 to the techniques use until today. Today, an intensive investigation is required considering that there are a lot of reports of pole shifts lately, to the point where these changes in the Earth structure are creating problems such as basic closures of the airport at certain areas. The data collected through first transferring the 420 years of North Pole position data from NOAA Geo Physic Data Center, putting it in an Excel spreadsheet, adding an intricate formula to find the distance between the coordinates of latitude and longitude, subsequently relating to each data point in the series and eventually putting it in the visual graph, reveals threatening information on the amount of pole shift over 10 to 20 years. The Geopolitics of the Earth is constantly changing sue to the weather changing simultaneously and the shifts of the magnetic field. The magnetic fields not only create huge global super storms, but they can be the reason for collapse of countries, societies, and cultures and also urge them to go on wars with each other. (Eye, 2011) The magnetic reversal is not something that happens on a periodic basis. It can take place in short periods of 100 thousands of years and some reversals are millions of the years apart from each other. This difference in the geomagnetic hemisphere seems to be the part of some agency. It does not happen on a uniform or regular basis. This stochastic pattern of events is non periodic as noticed by scientists. There might be a relationship between the main geomagnetic divergence and high impacts such as those happened 35 million years ago at the K-T boundary. Else, the relation between magnetic variations and impacts is a very minute one. The changes in the interior region of the Earth are themselves important most of the time. Therefore these impacts only form some part of the picture. The other reasons for these stochastic patterns might include a huge impact like Chicxulub which creates a gigantic magnetic reversal. The thing that we shall bear in mind is that these terrestrial impact sites are the most found in abundance on Earth; these include 29 percent of the possibilities as 71 percent of them are in the ocean. The impact of ocean is immensely affected by sea floor tectonic activity as well as the active weathering processes. If they happen on a huge scale so the geomagnetic field is suspended to certain extent. If this takes place, there should be a relation between the ages of impact and the timing of the changes of geomagnetic field. The time between changes will result in radiation going to the biosphere from space that would result into evolutionary changes. Thus, there is a distinct link between the time when evolution begin on Earth and the celestial events that start to take place. These alterations in the geomagnetosphere prevalent during flips have immense outcomes as the one we are facing today, the weather change. (Syzygyastro) The graph of Magnetic North Pole shift during 420 years is shown above. The shift of magnetic pole has doubled every 50 years since 1860. This change is very vital as in the last 150 years; the shift in the pole is prevalent in the same direction. The shift in the magnetic pole is growing at such a rate that in the last 10 years this shift has covered approximately half of the total distance that it covered in the last 50 years. The present state of the geomagnetosphere is very crucial because there is no define orientation of the north-south poles. The poles are just patched everywhere on the map. The pole has actually sped up magnificently. We do not know for now whether the speed will grow or slow down in the upcoming years. The aftermaths of main field are still persistent but North Pole is further from the equator than the South Pole. Some people believe that a pole reversal is overdue; this act might be the indicator of starting of that process. The images from Satellites have reflected that the overall huge field has been torn down into little local regions with many neutral zones. The spaces between these zones serve as an area where the cosmic and solar radiations can easily get into the surface of the Earth without any hindrance. But the atmosphere will pose a hindrance to these cosmic waves. In March 2010, NASA Space revealed that the moment of the sun is comparatively very quite according to the aural activity prevalent on Earth. Secondly the strength of magnetic field is almost zero which is broken down into hundreds of thousands of little coupled fields. It is believed that a time will come when this field will become neutral at last. (Eye, 2011) When the magnetic poles of North and the South do interchange with each other, then the direction of the magnetic fields of the Earth will change position. Magnetic decoupling occurs at the sun. What is magnetic decoupling? It is a cycle of 22 years that cause two events of decoupling. It is a magnetic cycle whose first event is when the sun goes through a complete magnetic unit when the origin attracts both the poles. Then the above mentioned unequally rotating plasma integers the magnetic field to first become stretched, then it would wound up and subsequently it gets twisted. Now from the buildup to the time when sunspot becomes maximum; the lines of the field they do break up and create the sunspot magnetic pairs, essentially at the interaction of sunspot group field lines. Finally, the twist in the field lines becomes so twisted that they themselves decouple once more and also restructure a totally different direction. Eventually, the number of sunspot decreases until the next blaze of winds creates the new decoupling event. The North Pole of the Earth is moving away from Northern Canada to the region of Siberia with an alarmingly increasing rate. We don’t know for now if this flow of drifting will increase further or not. If a reversal occurs for say, a full field reversal, so our current society is in danger as it relies to a huge extent on electromagnetic effects (e.g. communications, radio, satellite) and electricity for all reasons one can imagine. (Eye, 2011) Conclusion According to Newsolio Editor, as of April 16, 2010, in Adelaide, Australia, thousands of people were disturbed on late Friday night due to an immense Earthquake with an introductory magnitude of 3.2 on Richter scale which increased to 3.9. According to a spokesperson for the Australian governmental agency of science (Geoscience Australia), the centre of this earthquake of Adelaide was situated somewhere near Adelaide Hills. This increasing earthquake activity all across the globe is the gift of geomagnetosphere changes which is the benevolence of the tectonic movement. Our Earth is made up of thick sticky liquid with a very thin Earth crust on the surface of the Earth. The crust of the Earth is made primarily of pieces which are known as tectonic plates, they continue moving because of the core and mantle. As the geomagnetosphere experience changes so does the tectonic movement experience alterations. At the edges of these tectonic plates, also called faults, they will form the mountains and also speed up volcanic activity, they will stretch further from each other and then grind past each other and every one of them will try to push the other beneath it. The motions of these plates have changed considerably over the geologic history with pieces of the continent moving along every possible way they could. The edges of these plates are the focal points of earthquake activity. The areas of slip-strike zones, subduction zones- none of them are free from earthquakes. This fact was confirmed by a growing fault near Malaysia that created an earthquake, a tsunami and a seafloor drop which was felt over more than fifth of the Earth in 2004 on the 26th of December. (Newsolio, 2010) The shift of the Polar Shift is the chief reason for strong earthquakes to occur today. Both the Polar Shift and also the earthquakes are part and parcel of Earth’s boiling liquid Iron outer core, which goes into the solid Iron inner core as boiling as the Sun itself and also turns around at a much faster rate than the spinning of the Earth itself. As mentioned earlier, the crust and mantle of the Earth are on the top of huge amount of molten lava which creates the magnetic field of the Earth by Dynamo Effect. The North Pole has also experience rotations and movements since 1831 when it was located. It has moved to 1,100 km in total. Since 1970, the South Pole is also moving at a higher pace, from 10km to 40km on a yearly basis, which is four times than its initial speed. Life goes on even though there is a chance of magnetic reversals and pole shift each day. (Syzygyastro) References Syzygyastro.
