Which layer of the Earth takes up the most volume? Mantle Crust Core

The layer of the Earth that takes up the most volume is the mantle. The Earth's mantle is a thick layer of hot, semi-solid material that makes up about 84% of the Earth's volume. It is located between the Earth's crust and core and is composed of silicate rocks that are rich in iron and magnesium. The mantle is divided into the upper mantle and the lower mantle, with the upper mantle being more rigid and the lower mantle being more plastic and flowing. The Earth's crust and core are much smaller in volume compared to the mantle.
