Plate Tectonics Predicting the Past

Plate tectonics is a comparatively new notion, being introduced by Alfred Wegener in his 1915 publication of Origins of the Continents and Oceans, through his theory of continental drifts rather than publicly accepted by the scientific world before 1960s (Christopherson, 2011, p. 314). While Wegener’s theory wasn’t reputable until 50 years back, studying plate tectonics provides geologists a glimpse of Earth’s past by studying resources from Earth’s crust which may have been brought to the top (Harmon, 2011). Plate tectonics are the functions of upwelling of magma through volcanic activity, lithospheric plate activities, sea-floor spreading, subduction, and lithospheric deformation such as for example folding and faulting (Christopherson, 2011, p. 315). Katherine Harmon’s document in the Scientific American targets two geologists’ research of minerals compounded in diamonds which have been upwelled to Earth’s surface area from the crust through volcanic activity and how those diamonds offer insight to the origins of continental drift and supercontinents like Pangaea (Harmon, 2011). Harmon uses a research from Steven Shirey, a geologist from the Carnegie Organization of Washington’s Department of Terrestrial Magnetism. Shirey’s review is founded on the theory that volcanoes bring ancient diamonds from a huge selection of kilometers beneath Earth’s surface area that can
