How does seafloor spreading continental drift
WebJan 11, 2024 · The Mechanism for Continental Drift Seafloor spreading is the mechanism that Wegener was looking for! Convection currents within the mantle drive the continents. The continents are pushed by oceanic crust, like they are on a conveyor belt. Over millions of years the continents move around the planet’s surface. WebAs the ocean crust spread away from the higher ocean ridges, the guyots sank below sea level, becoming completely submerged. Hess also theorized that because the continental …

WebApr 9, 2024 · Seafloor spreading occurs at mid-ocean ridges and obtains basalt, the rock that forms the oceanic crust. Subduction zones are often observed near earthquakes. The biggest crash scene on Earth is the subduction zone. The oceanic crust is denser than the continental crust so when subduction occurs the oceanic crust goes under the …
WebThese scaffolded Continental Drift and Seafloor Spreading Cornell Doodle Notes combine two effective note-taking strategies and can be used during your Plate Tectonics unit to teach the concepts of the fossil and geologic evidence that led scientists to theorize about how and why Earth’s landmasses have moved great distances throughout Earth ... WebHow does seafloor spreading relate to continental drift? The upwelling of magma at the rift spreads out across the radius of the Earth like a conveyor belt. The continents are sitting on this “conveyor belt” and therefore are drifting. 1 Adam Wu Evolutionary neurosurgeon Author has 30K answers and 18.8M answer views 5 y

Seafloor spreading allows explain continental glide within the idea of plate tectonics. Whilst oceanic plates diverge, tensional stress motives fractures to arise in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools at the ocean ground to form new seabed.
