Outer Core

The Outer Core is the second to layer to the center of the Earth.  It is a magma like liquid layer that surrounds the Inner Core and creates Earth's magnetic field

Temperature

    The Outer Core is about 4000-5000 degrees Celsius. The Inner Core is so hot it causes all the metal in the Outer Core to melt into liquid magma.

Composition

    The Outer Core is composed of iron and some nickel.  There is very few rocks and iron and nickel ore left in the Outer Core because of the Inner Core melting all the metal into liquid magma

Thickness

    The Outer Core is about 2200 km thick.  It is the second largest layer and made entirely out of liquid magma.

Magnetism

    Because the outer core moves around the inner core, Earth's magnetism is created.
