WebFeb 23, 2008 · If the sea-floor was moving, then continents adjoining them might share that motion, just as Wegener had guessed. The main difference now seems to be that rather than pushing their way through a semi-fluid on which they float, the continents (or some of them) ride on top of "conveyer belts" in that fluid. 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 …

WebFeb 19, 2024 · Plate Tectonics. Plate tectonics refers to the process of plate formation, movement, and destruction.
