Explanation:

The lithosphere is the rigid outer layer of the Earth. Earth's tectonic plates are made up of the crust and the uppermost part of the mantle, which together form the lithosphere. The asthenosphere is a semi - fluid layer beneath the lithosphere. The inner core is the innermost layer of the Earth (solid iron and nickel). The mantle is a layer below the crust, but the plates are not just the mantle.
