WebNew seafloor is generated from The upper mantle at the mid-oceanic ridges, spreads laterally outward, and is eventually subducted, or consumed, at the margins of ocean basins.Subduction may also occur between two regions of oceanic crust, with older, denser sections underthrusting younger, less-dense ones.

Web1 apr. 2010 · As the plates move, new sea floor can be created. The plates form three different kinds of boundaries: convergent, divergent, and transform. Convergent … Web6 nov. 2024 · The last type of plate boundary is the transform boundary, which is where two plates slide past one another. Unlike the other two types of plate boundaries in which new seafloor is created at divergent boundaries and where old seafloor is subducted at convergent boundaries, transform plate boundaries neither create nor destroy the seafloor.

It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates. The vast majority of volcanic activity on the planet occurs along the mid-ocean …

WebThis frozen lava becomes the new seafloor. Since new seafloor stays hot for a long time, it is more buoyant (floats higher) than the older seafloor, forming a high ridge that looks like an underwater mountain chain. We call this ridge where new seafloor is created a ‘mid-ocean ridge’. The same process happens in the middle of the Atlantic ...
