(centered in Nevada this area is about 1500 kilometers wide and runs about 4000 kilometers North/South). Continental crust is thickest beneath mountain ranges and extends into the mantle. Plate Tectonics * The Earth’s surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle). * These plates are in constant motion travelling at a few centimetres per year. * The ocean floors are

Plate Tectonics & Marine Resources The ocean is one of the worlds greatest natural resources. It provides the Earth’s population with numerous amounts of resources that have value and others that provide pure enjoyment. Transportation is one of the major uses of the ocean‚ along with recreational activities‚ and inspiration. As for resources extracted from the ocean that provide the economy with value‚ three of the main include oil‚ minerals‚ and food. Oil or gas are the top resources extracted

how you could compare continental drift‚ sea-floor spreading‚ and plate tectonics? Well there are actually plenty of ways to compare these three topics in earth science. You could compare these topics in similarities; continental drift and plate tectonics both start on the same basis of idea‚ that Earth’s lithosphere is made up of tectonic plates. You could also state some differences‚ such as continental drift occurs on all plate types‚ but sea-floor spreading only takes place on oceanic crust‚

Plate Tectonics Plate Tectonics The theory of plate tectonics was developed in the 1960’s and states that the earth is broken into a number of shifting plates. Plate tectonics also provides geology with a comprehensive theory of how the earth’s crust moves. In this essay I will explain the different types of plate movements‚ how the plates move and how this movement affects earthquakes and volcanoes. To begin‚ there are three different types of plate movement; divergent boundaries‚ convergent

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

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

“Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid” Discuss the extent to which you agree with this statement (40m) The theory of plate tectonics 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 the plates converge‚ diverge or move past each other. These plates

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

“The hazards presented by volcanic and seismic events have the greatest impact on the world’s poorest people.” To what extent do you agree with this view? (40 marks) Volcanic and seismic events can take place all over the world and therefore both more economically developed countries (MEDCs) and less economically developed countries (LEDCs) can be affected. In the last 30 years there have been multiple examples of where volcanic and seismic events have had an impact on both MEDCs and LEDCs. Some
