Divergent Boundary Definition Examples Lesson Study Divergent boundary. in plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. divergent boundaries within continents initially produce rifts, which eventually become rift. Divergent plate boundaries. divergent plate boundaries are locations where plates are moving away from one another. this occurs above rising convection currents. the rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. this lateral flow causes the plate material above to be dragged along in the.
Facts About The Divergent Plate Boundary Explained With A Diagram Figure 2.4.1 2.4. 1: faulting that occurs in divergent boundaries. in places where the continental plates are very thick, they reflect so much heat back into the mantle it develops strong convection currents that push super heated mantle material up against the overlying plate, softening it. Updated on january 17, 2020. divergent boundaries exist where tectonic plates move apart from each other. unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each. the vast majority of divergent boundaries are found in the ocean, where they were not mapped or understood until the mid to. Continental rifting. continental rifting occurs where divergent boundaries form within continental landmasses: • involves rifting (pulling apart) of continental crust (cc) only. • forms possibly from convection in the asthenosphere. • large amounts of sediments are usually produced in continental rifting zones. A divergent boundary occurs when two tectonic plates move away from each other. along these boundaries, earthquakes are common and magma (molten rock) rises from the earth’s mantle to the surface, solidifying to create new oceanic crust. the mid atlantic ridge is an example of divergent plate boundaries.

Most movement occurs along narrow zones between plates where the results of plate tectonic forces are most evident. there are four types of plate boundaries: divergent boundaries where new crust is generated as the plates pull away from each other. convergent boundaries where crust is destroyed as one plate dives under another. Figure 10.4.1 10.4. 1 a map showing 15 of the earth’s tectonic plates and the approximate rates and directions of plate motions. rates of motions of the major plates range from less than 1 cm y to over 10 cm y. the pacific plate is the fastest, followed by the australian and nazca plates.
