Continental drift is the idea that the earth’s continents are drifting away‚ relative to each other across the ocean bed suggested by Alfred Wegner as part of his wider theory on plate tectonics. The plate tectonic theory suggested by Alfred Wegner in 1915 was that millions of years ago all the continents were joined together in one mass of land called ‘Pangaea’‚ the evidence for this was that coal was found on Antarctica‚ the shape of Africa and south America fit together and same fossils were

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

How Plate Tectonic Theory Explains Mountains Shadi Alostaz The Plate Tectonic Theory explain mountains because they form in oceans. Mountains primarily form at plate margins‚ or places where boundaries of plates meet at and interact (Nagel and Sawinski 1). The mountains form in oceans mostly because of the mid ocean ridges. The mid ocean ridges converge‚ creating underwater mountains. The mountains above ground are mostly caused‚ and responsible for convergent plate boundaries The Plate Tectonic

‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries

Surely you understand that Aunt Caroline. No one wants their lifestyle to be taken away from them. Anyway Aunt Caroline‚ let me tell you all about the fighting.

A Divergent plate boundary is a tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth’s surface between the two plates. The middle of the Red Sea and the mid-ocean ridge (running the length of the Atlantic Ocean) are divergent plate boundaries. Divergent boundaries are characterized by a rift in the surface of the earth along the midocean ridges that exist in all of the major ocean basins. The ridges are composed of volcanic

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

The plate tectonic theory is the theory that describes large amounts of movements in the Earths lithosphere‚ whereby Continental and Oceanic crust is moved‚ destroyed and made from this. The idea of plate tectonics builds on other concepts such as continental drift‚ where continental plates over millions of years move‚ however the concept of continental drift was not accepted for some time‚ and there were many other theories to suggest that something else took place‚ as the idea of the earth moving
