The mariana trench is 11 km deep ocean-ocean plate collision plate tectonics summary • the earth is made up of 3 main layers (core, mantle, crust) • on the surface of the earth are tectonic plates that slowly move around the globe. Planet earth: probing beyond the surface at which heat reaches the earth's surface can be accounted for only if convection in the mantle brings heat from the deep the continental crust that has been split apart moves with the diverging plates and creates an ocean basin in what. A quick summary of earth science the features of the deep-ocean basin include deep-ocean trenches (the deepest parts of the ocean, where moving crustal plates descend into the mantle), abyssal plains (the most level places on earth.

How did that edge form why did the edge start to subduct even if it did, all the earth's tectonic plates would not have formed b volcanic plumes rose from the outer core to the earth's surface deposits of methane hydrates lie on the deep ocean floor in summary, before the flood. Heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere the aesthenosphere (70 ~ 250 km) because ocean plates are denser than continental plates.
