one another. These pieces slowly assumed their present positions as the continents. PLATE TECTONIC THEORY Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. There are seven or eight major plates and many minor plates. Where plates meet‚ their relative motion determines the type of boundary: convergent‚ divergent‚ or transform

evidence for plate tectonics. It is the patterns on the rocks which presented a problem with the theory. There was thought to be a problem with the description of the movement being “slow and gradual”. According to scientists and geologists the movement would have been performed at a rapid speed. A physicist then predicted where the evidence for this rapid movement could be found and it was later proved that the argument against the theory was correct. The biblical view of plate tectonics conveys an

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

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

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

it is made up of large plates beneath the crust and when the plates move‚ it changes the surface. There are four types of plate boundaries and they are divergent boundaries‚ convergent boundaries‚ transform boundaries‚ and plate boundary zones. Convergent boundaries are where the crust is broken‚ and one plate goes over it‚ divergent boundaries is where new plates are created while the plates pull away‚ transform boundaries is where the crust may be produced or more‚ plate boundary zones are boundaries

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period
