How Does Seafloor Spreading Support Continental Drift?

WebSeafloor spreading is the process by which magma within the Earth's crust emerges at the mountain ranges and separates the sea floor. The magma creates a new section of sea floor, which explained why the oceanic crust looked so young -- … WebConverging currents drive plates into each other. Diverging currents pull them apart. This is mostly true. Hot mantle rock rises from the core and moves along under the crust until it grows cool and heavy and sinks back down again. But the plates aren't just passively riding these currents around like a bunch of suitcases at the baggage claim. fly red teal black helmet

WebSeafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading … WebWhen the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth’s surface. Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics.

WebMar 25, 2024 · As the plates move away from the flanks of the ridges, they carry the continents with them. On the basis of all these factors, it may be assumed that the Americas were joined with Europe and Africa until approximately 190 million years ago, when a rift split them apart along what is now the crest of the Mid-Atlantic Ridge. greenpeace at tory conferenceWebMar 29, 2024 · Scientists agree that continents rest on rocks called tectonic plates, which shift and move. Sea floor spreading further supports the continental drift theory. As molten rock rises from the Earth, it forms new crust between the plates. When this occurs, the sea floor grows wider, pushing the two continents apart. fly redmond to seattle

WebMay 2, 2024 · Seafloor spreading is the mechanism for Wegener's drifting continents. Convection currents within the mantle take the continents on a conveyor-belt ride of oceanic crust that, over millions of years, takes them around the planet's surface. The spreading plate takes along any continent that rides on it. 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.
