At What Type Of Plate Boundary Is Oceanic Crust Created? Oceanic crust is created at divergent boundaries, such as the mid-ocean ridge. Oceanic crust is destroyed at convergent boundaries where subduction results in a trench, such as the Mariana Trench or Cayman Trough.] At which type of boundary is new oceanic crust created quizlet? The
How Do We Know The Continents Were Once Connected? Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics. Did the
Which Was An Argument Used To Dispute The Theory Of Plate Tectonic? Answer: Option D, Continents cannot cut through the ocean floor. Explanation: It was believed earlier that oceans were the land bridges that used to connect different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between
Which Of The Following Does Not Play A Role In Convection In The Mantle? The core does not play an active role in mantle convection. The magnitude of the bottom TBL depends on the cooling rate of the mantle, the pressure and temperature dependence of the physical properties and the radioactivity of the deep mantle.
Who Supported The Theory Of Continental Drift? The theory of continental drift is most associated with the scientist Alfred Wegener What supported the idea of continental drift? The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. What
Why Are There So Many Volcanoes In The Pacific Northwest? The distribution of volcanoes in the northwest and Alaska is the result of plate tectonics. In the northwest, the oceanic Farallon Plate is being pushed beneath (subducted) the continental margin of the North American Plate. … The melt, called magma, rises to the surface to
Do Plates Move Horizontally? A transform plate boundary occurs when two plates slide past each other, horizontally. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. What direction
Why Is The Pacific Plate Exceptional? An exception is the Pacific plate, which is nearly all oceanic crust. Oceanic crust (basaltic) is thinner and denser than thick and buoyant continental (granitic) crust. Because of their differences in movement and makeup, the plates interact with each other in various ways. What makes the Pacific plate unique
Why Is Convection Current Important? Convections currents in the earth’s mantle are thought to be the driving force of plate tectonics. Where the hot magma is brought near the surface by the convection currents a divergent boundary is created. The divergent boundaries form new oceans and widen existing oceans. Why is the convection important? This
Which Way Are Tectonic Plates Moving? The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per
