WebEarth's mantle is a layer of silicate rock between the crust and the outer core.It has a mass of 4.01 × 10 24 kg and thus makes up 67% of the mass of Earth. It has a thickness of 2,900 kilometers (1,800 mi) making up about 84% of Earth's volume. It is predominantly solid but, on geologic time scales, it behaves as a viscous fluid, sometimes described as having … WebCooler, older, oceanic lithosphere sinks into the mantle at_____.

Webanic lithosphere at the edge of a plate sinks into the man-tle. The oceanic lithosphere sinks because it is colder and denser than the mantle. As the lithosphere at the edge of the plate sinks, it pulls the rest of the plate along with it. This process is called slab pull. Another possible cause of plate motions is ridge push.
