What is the core of the Earth?

Back

The core is the innermost layer of the Earth, composed mainly of iron and nickel, and is divided into a solid inner core and a liquid outer core.

What is the difference between igneous and metamorphic rocks?

Back

Igneous rocks form from cooled magma, while metamorphic rocks are formed from existing rocks that have been changed by heat and pressure.
