Plate Tectonics Paper Earthquakes, volcanoes, mountains and the Earth’s crust are unique yet have one common denominator; the amazing topic of plate tectonics. Plate tectonics has a place or specifically places a role in each of these natural wonders of the world. In the following, Team C will discuss the theory of plate tectonics and how the theory shaped the form and composition of the movement within the Midwest region of the United States. A discussion of various geological events and the types of rocks that formed because of these events will also be covered including the importance of the economic value of these rocks to the Midwest region

movement was felt as far away as South Carolina and Massachusetts to the east, Louisiana to the south and Canada to the north. The Midwest also underwent “a complete cycle of continental rifting, ocean opening and collision that created the Ouachita orogenic system” as North America was created during the late Proterozoic and Paleozoic. This cycle created the Arkansas-Oklahoma Ouachitas and Arbuckle (Oklahoma) mountain ranges (Aber, 2003).
Various types of rocks
The New Madrid Seismic Zone is also known as the New Madrid Fault Line. A fault is a thin zone of crushed rock that separates the Earth’s crust. Whenever an earthquake takes place, it occurs on one of the faults. Then the rock on one of the sides slips with respect to the other. The fault line is made up of reactivated faults. The reactivated faults formed when North America began to separate. Faults were formed next to rift and igneous rocks were formed from the magma that was pushed up to the surface (Wapedia (2010). The rift was covered with younger sediments. The sediments that covered the rift included Mesozoic and Cenozoic sedimentary rocks of the Mississippi embayment. Large amounts of the sediment was loosely consolidated, soft and sandy as a result of the ground shaking, ground deformation, slides, slumps, and liquefaction. A mass of intrusive igneous rock (also known as pluton, mass of igneous rock and a deep reservoir of magma)
