Answer 2

Answer:

By composition, Earth is divided into core, mantle, and crust. By mechanical properties, the crust and upper mantle are divided into lithosphere and asthenosphere. Continental crust is felsic, oceanic crust is mafic, the mantle is ultramafic, and the core is metallic.

Explanation:

Hence, the magma found in deeper mantle will be mafic
