Physical Properties of Earth`s Layers
... What are the physical layers of Earth? The physical layers of Earth are the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The lithosphere is the outer layer of solid rock that is found at Earth’s surface. It includes both the crust and the solid, uppermost part of the mantle. T ...
