WebThe movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere. Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart. The ocean floor then finally gets recycled into the mantle and a seafloor plate meets a continental plate, (subduction). Earth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 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 the consistency of caramel. Partia…
