WebSeafloor Topography Continents fit together along the edges of their continental shelves. Mid-ocean ridges and deep-sea trenches develop at the boundaries of the moving plates. Volcanic islands and seamounts develop where a plate moves over a stationary hotspot. The new earthquake data revealed three startling observations. WebThese plates move due to convection currents in the mantle. Heat from the core makes magma in the mantle rise towards the crust. As the hot current nears the crust, it begins to cool and sink back ...

WebMar 25, 2024 · The ocean floor is thus pushed at right angles and in opposite directions away from the crests. By the late 1960s, several American investigators, among them Jack E. Oliver and Bryan L. Isacks, had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory.

WebMay 6, 2024 · Plates move apart at mid-ocean ridges where new seafloor forms. Between the two plates is a rift valley. Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro.
