Question

define different layers of earth??

Answer 1

The interior structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.

Answer 2

The earth is made up of several layers and each has unique properties, characteristics, composition and affects the inner processes of the earth differently. The layers are from the exterior to the interior and are largely grouped into four including: the crust, the mantle, the outer core, and the inner core.
The Earth’s CrustThe earth’s crust is the outmost and first layer of the earth.
The MantleThe mantle sits on top of the outer core and is the second layer of the Earth. It is by a considerable margin the densest layer of the earth, The Earth’s CoreThe Earth’s core is the innermost section of all the layers. It is distinctly made up of two parts which are the outer core and the inner core. Both the outer and the inner core are mostly made up of iron, nickel and other heavy metals as conjured by geologists
