The initial theory of continental drift was put forward by a German meteorologist Alfred Wegener in 1915. This theory did not seem credible until it was connected with the plate tectonic theory in the mid 1960’s. The Tectonic plate theory had an advantage over previous predictions as it could be supported by observed occurrences. One such thing that supports these two theories is that seen from space the continents look as if they might once have been joined together. This possible idea was then

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms

processes were plate tectonics‚ glaciation‚ and weathering & erosion. One example of plate tectonics in CT is the Connecticut River Valley. The Connecticut River Valley was also formed by glaciation but first came the plate tectonics. When the plates divided it created a rift valley‚ (When the land on two sides rises but the middle land lowers or stays the same.) rift valleys can be formed by earthquakes and some other natural forces as well. This is only one example of plate tectonics. Another example

June 2011 plate tectonics and associated hazards Comment on the extent to which the features shown in the image support the theory of plate tectonics. To begin with we can see that many of the landmasses appear as separated jigsaw pieces with their complementary shaped coastlines. One example of this is how the North Western coastline of Africa could quite easily ‘slot into’ the North Eastern Coastline of America. This suggests that in the history of the Earth‚ these two land masses were once connected

Plate Tectonics Press Release GLG/101 July 13‚ 2012 Plate Tectonics Press Release Hello everyone‚ my name is John doe and I am the Director of Earthquake Preparedness’ for Los Angles. I am here today to talk to your about earthquake preparedness. During this press release I will be describing the hazards associated with earthquakes in Los Angeles. I will discuss the origin and causes of earthquakes and the relation of earthquakes to plate tectonics and faults in Los Angeles

Plate Tectonics Press Release GLG.101 August 16‚ 2013 Plate Tectonics Press Release Natural destroys are a part of the nature of the world. There are many different kinds of natural destroys hurricanes‚ tornados‚ tropical storms‚ and earthquakes. The great state of California is no stranger to its part of natural destroyers. Many cities in the state have had its share having earthquakes. Earthquakes are produced by abrupt motion along a fault when friction that resists such motion is overcome

To answer the following question: Relate the generation of all three rock types (igneous‚ sedimentary‚ and metamorphic) to plate tectonics. I will start first‚ with igneous rocks and how does it relate to plate tectonics. Second‚ with sedimentary rocks and progressively keep on answering how all three types of rocks relate to plate tectonics. Will be giving as much information I learned from class. To assure‚ answer is fully answered. The igneous process begins when magma forms by melting at depth

evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported with multiple pieces of evidence but his theory was never

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events(40) The global seismic and volcanic activity is concentrated along the margins of the earth’s plates‚ which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new science. It’s partially explained in the sense that we still don’t know fully about how the plates came together‚ what they were before they were the seven continents we know today. We already know‚ or have a theory‚ about what our world was like a long time ago and so if we already know that the plates can pull and push against each other‚ then surely
