Answer:
The lower area of the Earth's mantle is the densest.
Explanation:
- The upper part of the mantle is constituted of magma and other semisolid material.
- The tectonic plates of the 'Earth's crust' float on this magma that is present in the upper mantle.
- The lower mantle is denser than the upper mantle and is made up of solid material.
- It forms the boundary between the semisolid upper mantle and the semisolid outer core of the Earth.
