The Earth’s Interior Crust (Lithosphere) Mantle Outer Core Inner Core

(1512 miles deep) a solid contains both iron and nickel. like a magnet, a compass. It generates a magnetic field that protects the earth from flying out of orbit. Gravitational pull

Outer Core (1419 miles deep). This is much like the inner core with the exception that it is a liquid Made of liquid nickel and iron Contains sulphur and oxygen which reduces the boiling point of iron & nickel.

Lower Mantle Occupying 1789 miles (upper & lower) iron and magnesium Upper and lower It is very hot!! Mostly solid (lower mantle)

Upper Mantle Occupying 1789 miles magma (iron and magnesium). Upper and lower It is extremely hot!! goopy; very plastic- like. (upper mantle)

Crust Also called lithosphere This is the top layer of the earth, which is basically hardened mantle (magma). It contains two segments, the oceanic and continental crusts.

Crust… cont’d For instance, if you drained all of the water from earth, then there would be one, giant Continental Crust. Likewise, if you flooded everything, you'd have one, giant Oceanic Crust.
