How are oceanic ridges created
Web23 de jul. de 2024 · Continental crust is low in density whereas oceanic crust has a higher density. Continental crust is thicker on the contrary the oceanic crust is thinner. Continental crust floats on magma freely but oceanic crust floats on magma scarcely. Continental crust cannot recycle whereas oceanic crust can recycle it. Webcrust formed near mid-ocean ridges are older than those farther from the ocean ridge 10. as a new sea floor is formed at the mid ocean ridge, the old sea floor farthest from the ridge is destroyed. which of the stated processes describes how the oceanic crust plunges into the earth and destroyed at the mantle

WebDivergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley. Divergent boundaries can create massive fault zones in the oceanic ridge system. WebThus, for each segment of new ocean floor created at the ridges, an equal amount of old oceanic crust is destroyed at the trenches, or so-called subduction zones. It is for this …
WebRift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. church church hittle antrim attorneysWebDivergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest. church church toilet seat round
