Which of Earth's layers is comprised mainly of extremely hot liquid metals?

A. Crust

B. Mantle

C. Outer Core

D. Inner Core

Answer: C outer core.

Explanation:

Outer core is a liquid mix of iron and nickel.

Option (C)

Explanation:

The earth's core is comprised of denser and heavier elements such as iron, nickel and other siderophile elements. These are accumulated at the center of the earth, where the temperature and the pressure condition is extremely high. The inner core is made up of hot solid materials, but in the outer core, these materials are present in the liquid state. The heat energy supplied from this region outward allows the lithospheric plates to move over the layer of the asthenosphere.

Thus, the correct answer is option (C).
