Front

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is the outer core?

Back

The outer core is the liquid layer of the Earth's core, composed mainly of iron and nickel, located beneath the mantle.

Front

What is the inner core?

Back

The inner core is the solid, innermost layer of the Earth, composed primarily of iron and nickel, and is extremely hot.
