Whilst oceanic plates diverge, tensional stress causes fractures to arise within … WebNov 9, 2024 · The Theory of Plate Tectonics builds on Wegener’s Theory of Continental Drift. In the Theory of Plate Tectonics, it is tectonic plates, rather than continents, which are moving. Tectonic plates are pieces of the lithosphere. The lithosphere is made up of the crust and the upper mantle. These pieces float on a layer of partly liquid rock ...

WebApr 5, 2024 · April 5, 2024 by husin. 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. Continental Drift vS. WebThe theory of continental drift was one of the earliest ideas explaining how the continents move. The theory of continental drift suggests that the continents drift across the ocean and are not stationary on earth's surface. Alfred Wegner proposed that all of the continents on Earth were once fitted together into a single super continent that ...

WebJun 30, 2015 · Seafloor spreading adds material to oceanic plates, causing the oceanic plate to come into contact with other plates but not necessarily causing those affected plates to "drift". Explanation: The image below …
WebMay 20, 2024 · According to this theory, Earth’s crust is broken into roughly 20 sections called tectonic plates on which the continents ride. When these plates press together and then move suddenly, energy is released in the form of earthquakes. That is why earthquakes do not occur everywhere on Earth—they’re clustered around the boundaries of tectonic …
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.
