what was the plate tectonic revolution?
98865
It was once thought that land on earth is stationary and that the continents had always been their current shape, even though they may have been covered by more water.\n\nMore recently however, it has been discovered that the continents were actually all one mass of land and at one point separated, floating apart on sheets of plate tectonics.  \n\nProof came quickly.  It is now easy to see the east coast of South America fitting into west Africa for instance.  Bones of related land-dwelling creatures were also found on the coastlines of the two distant continents.

There is no right answer for this question. Just because the plates are moving and right now most of the land mass is in the northern hemisphere. That is just where the bulk of it is right now, and someday it will change.

this is a vague queston. But I believe i know what you are asking. Well He already believed that Pangea had formed and broken apart. Evidence from Glacial Striations and rock formations, not to mension an almost perfect mactch of shorelines. I guess it would have more support for his theory. He concluded that the continents were moving. What he could not prove was the mechinism for the movement. it is not actually the continents moving. They are hitching a ride on the techtonic plates.

The plates consist of an outer layer of the Earth, the lithosphere, which is cool enough to behave as a more or less rigid shell. Occasionally the hot asthenosphere of the Earth finds a weak place in the lithosphere to rise buoyantly as a plume, or hotspot. \n\nOnly lithosphere has the strength and the brittle behavior to fracture in an earthquake. \n\nThe map below locates earthquakes around the globe. They are not evenly distributed; the boundaries between the plates grind against each other, producing most earthquakes. So the lines of earthquakes help define the plates: \n\n\nIn cross section, the Earth releases its internal heat by convecting, or boiling much like a pot of pudding on the stove. Hot asthenospheric mantle rises to the surface and spreads laterally, transporting oceans and continents as on a slow conveyor belt. The speed of this motion is a few centimeters per year, about as fast as your fingernails grow. The new lithosphere, created at the ocean spreading centers, cools as it ages and eventually becomes dense enough to sink back into the mantle. The subducted crust releases water to form volcanic island chains above, and after a few hundred million years will be heated and recycled back to the spreading centers.

It will pretty much look the same. Normal plate techtonics\nmoves continents very very slowly and you need more then a\nthousand year window to see any real difference. Just look\nat maps from the year 1006 if you don't believe me.

The tectonic plates are "floating" on a liqid mantle that has convection currents.  These convection move the plates around the globe.  This is the science behing plate tectonics

Thats the theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges. \nFirst proposed in the early 1960s by the American geologist Harry H. Hess, its major tenets gave great support to the theory of continental drift and provided a conceptual base for the development of plate tectonics.\n\nBUT...\n\nAlfred Wegner came up with continental drift! \n\nA geological theory that the relative positions of the continents on the earth's surface have changed considerably through geologic time. Though first proposed by American geologist Frank Bursley Taylor in a lecture in 1908, the first DETAILED theory of continental drift was put forth by German meteorologist and geophysicist Alfred Wegener in 1912.

no... because i know, before my class even started the topic of year 9 geology (i think the topic is called "Reading the Earth") - and i'm in year 9, i think this is form two for other countries and can be also known as grade 9), i know that the mountain ranges in the asian area was cause by plate tectonics crashing into each other - and through the topic i'm studying right now, I learnt that the type of boundary that is between the plates is called the collosion boundary where two plates of similar thickness collide creating mountain ranges as the ground is pushed upwards and downwards.

I don't think it was revolution!\n\nIt was evolution.\n\nEven if there was some creation involved (which I highly doubt), it still has to come down to evolution. Otherwise, how do the creator come to be? Anwser: it evolved.\n\nmale, 45, Louisiana

At Divergent Margins, plates move apart and new crust and lithosphere are created. This usually occurs at a Mid-Ocean Ridge, but divergent margins can also occur on land. The Great Rift Valley of Africa is a example of a divergent margin that is splitting the African Continent into two parts. Eventually, as the rift continues to open, a new ocean basin will be formed. \nWhere Oceanic Plates move apart, Magma wells up from the Mantle and crystallizes against the trailing edges of the plates. This is how new Oceanic Lithosphere is formed. Spreading across Mid-Ocean Ridges is symmetrical, and Normal Faulting predominates. Earthquakes are weak but common. As this new, hot Lithosphere cools and moves away  from the Mid-Ocean Ridge it Isostatically adjusts and settles lower into the Mantle, increasing the depth of the sea floor. This change produces characteristic Mid-Ocean Ridge Stratigraphy. \n\nSea floor Volcanism and Hydrothermal Activity are common along Mid-Ocean Ridges. \n\nMagma cooling at Mid-Ocean Ridges continuously records variations in the polarity of the Earth's magnetic field.

The earth's crustal plates float on a layer called the Mantle, and it is convection in this mantle which drives the continental drift or plate tectonics.

(m)\n\nAustralian and American researchers investigating forces exerted on the Indo-Australian tectonic plate have discovered that the considerable stresses being exerted on the plate could be leading to its breaking up.\n\nARC Professorial Fellow, Mike Sandiford, from the University of Melbourne’s School of Earth Sciences was recently awarded ARC funding for research aimed at understanding the forces that drive the motion of the Earth’s tectonic plates and the distribution of stresses in the Earth’s crust that give rise to great earthquakes such as the magnitude 9 Boxing Day Sumatran quake.\n\nProfessor Sandiford says the research shows that as much as 10 per cent of the huge amounts of energy being created at plate connection points at Sumatra and Java are being transferred back into our plate and causing major stresses.\n\n“This is enough stress to contribute to mild earthquake activity in the central regions of the plate, such as in the Australian continent or central Indian Ocean, and provides us with clues as to why our plate has been slowly breaking up,” he says.\n\n“The Indian Ocean quakes are, in effect, leading to the active rupture of the Indo-Australian plate into separate Indian and Australian plates. This new research provides us with important information about the stresses that are driving this drawn out tectonic plate divorce.”\n\nThe research, which was conducted in collaboration with Wouter Pieter Schellart of the Australian National University and David Coblentz of the Los Alamos National Laboratory in the US, will be published in the journal Geology (27 January).\n\nThe research is also important for understanding why smaller intra-plate earthquakes such as the 1989 Newcastle quake, which occurred nowhere near the edge of the plate, take place. Up to now, why earthquakes occur in apparently safe zones in the centre of plates has not been very well understood.\n\nProfessor Sandiford says, “Earthquakes such as the 1989 Newcastle quake that killed 13 people and caused more than $1 billion in damages are just one manifestation of mild tectonic activity that has been affecting the Australian continent for the last 5-10 million years.”\n\nThe new research shows that stresses originating at points of collision between two plates are being dissipated back into our plate and generating enormous internal stresses.\n\nThe ARC funded project will map the spatial and temporal pattern of this tectonic activity and relate it to the factors that drive the motion of the Indo-Australian plate.\n\n“This research will contribute to our understanding of the factors that drive plate motion, to earthquake risk assessment in Australia and other comparatively stable continental regions, and to the factors that have shaped our distinctive Australian landscapes,” he says.\n\nBACKGROUND INFORMATION\n\nWhat causes tectonic plates to move?\nThe Earth is made up of a series of layers. The outermost layer is called the crust and the innermost is the core. In between lies an area called the mantle (in turn made up of upper and lower mantle), which is arguably the most important when it comes to understanding where big earthquakes occur.\n\nThe outer part of the Earth, comprising the crust and top 100 or so kilometres of the mantle (together called the lithosphere), consists of a collection of eight major plates which almost fit perfectly together. The continents and oceans all lie on these plates, the major ones referred to as the African, Eurasian, Indo-Australian, Antarctic, Philippine, Pacific, Nazca, North American and South American, depending on their geographic location.\n\nThese plates (also referred to as tectonic plates) float on the softer mantle underneath. Convection currents within the upper mantle layer are a major driving force driving plate motion and therefore behind earthquake activity.\n\nThe lower sections of the mantle closest to the molten core of the earth are also the hottest parts of this la

Not at all. \n\nThe most convincing evidence that led to the acceptance of plate tectonic theory are stripes of magnetized rock that are arranged parallel the mid-ocean ridges and continue all the way to the edges of the ocean basins. These stripes grow progressively older in age as they approach the edges of the oceans, and correspond to past reversals of the earth's magnetic field. Each stripe formed during a period of Earth's history while the magnetic field orientation was steady, and as the field reversed, a new stripe with opposite orientation was formed. Here is a diagram that represents this:\nhttp://www.ucmp.berkeley.edu/geology/tecmech.html\n\nOther types of evidence that changed the paradigm from the old continental drift to plate tectonics was the discovery of mid-ocean ridges, which are volcanic chains larger than the Himalayas that stretch along the center parts of each ocean basin. These are active volcanic zones that are constantly forming new oceanic crust. \n\nPlate tectonics is an especially well proven and robust concept. Evidence of past plate movement is found in all parts of geology, from deposits of oil in both Africa and Brazil that came from the same source, to widespread rocks deposits on different continents that match in composition and character. Biological evidence in the form of fossils adds to the story, and plate tectonics is an important complement to the Theory of Evolution because it explains why some related organisms have had the opportunity to evolve differently in isolation. \n\nAs mentioned, the relatively new science of geodesy, prompted by satellite technology, can now measure the movement of continents precisely, and also can measure the changes in elevation of mountains as they rise. \n\nIf you would like to examine the changes in the earth's continental plates as a result of plate tectonics over time, here is a set of maps that show the movement of the earth's plates in the past and projected into the future:\nhttp://www.scotese.com/
