Earthquakes and Volanoes

-Amrita Volcanoes and earthquakes are seemingly very different geological events, til now they are actually closely re latelyd two go forth from strikements of Earths crust. Earths crust the lithosphere is composed of several study plates and many an mated(prenominal) minor plates that change shape and position. Over time, these architectonic plates move, act with each other, and are responsible for the formation of naval basins, portion ranges, islands, volcanoes, and earthquakes. The theory of plate tectonics is relatively new. In the advance(prenominal) 1900s, Alfred Wegener first developed a theory of continental stray based on a collection of evidence that showed notion similarities in rocks and fossils found on continents separated by enormous distances. Sometime later, Arthur Holmes proposed a mechanism to explain how the continents could have move across Earths surface. He proposed that circular convection currents of molten material of late within Earth could provide ample force to split up and move continents. By the late 1960s, evidence of seafloor spreading helped to commit the now well-accepted theory of plate tectonics. Three main types of boundaries incarnate between tectonic plates. The first, called a divergent boundary, occurs most practically at mid-oceanic ridges. Here, two plates move away from each other, forming a break, or rift, in Earths crust. Magma from the mantle rises to fill the gap, creating new crust. The brand type, called a convergent boundary, occurs where two plates moving toward each other meet. If at least one of the plates is made up of relatively dense oceanic crust, the denser of the two plates subducts, or lantern seashores beneath the other. If both(prenominal) plates are made up of continental crust, very little subduction occurs. Instead, the plates buckle and fold to create valleys, ridges, and high mountain ranges. The expiry type of boundary is called a transform  boundary. At these locations, plates slide ! roughly alongside each other in verso directions. The plates often get stuck as...If you want to get a climb up essay, order it on our website: OrderCustomPaper.com
