Earth is composed of three concentric layers. What are they, and how do they differ?
What will be an ideal response?
The three major concentric layers are the crust, mantle, and core.
The crust is the thin, solid surface layer, and includes compositionally different oceanic and continental crust. The mantle is the thickest layer and is also mostly solid but includes the less rigid asthenosphere. The core is metallic, with an inner solid part and an outer liquid part.
