Compare and contrast the outer core and the inner core.

Outer Core:The outer part of the core is liquid and hot.It gets hotter the deeper you go (around 9000 degrees F in the center - your oven only goes to about 600 degrees F)It's so hot that rock melts. Melted rock is called magma.It's 1400 miles thick,and Earth's magnetic field results from movements in the outer core.Inner Core:It is only 800 miles to the center. It's shaped like a ball, or a sphere,And it's solid.They both have the same composition, which is Fe-Ni alloy. They are both high in temperature.
