What are the main features of the mantle and the core?

Dear Student

Mantle: The mantle is one of the three main layers of the Earth. It lies between the innermost layer, the core , and the thin outermost layer, the crust.The mantle consists of solid or semi-solid iron-magnesium silicate rocks, not molten rocks. It is divided into inner and outer zones, and these represent changes in the mineral composition. 
Core: The core is beneath the mantle. It is the deepest and hottest layer of the Earth. It is made almost entirely of metal. The core is made of two layers: outer core and inner core.The outer core consists mostly of liquid metallic iron and nickel while the inner core consists of solid metallic iron and nickel.
