Earths spheres

Earths geosphere is made of 4 layers, the crust, the mantle, the outer core, and the inner core. Some people make the outer and inner core one calling them the core, but really they are both different 

because the outer core is liquid at 7952 fahrenheit 

and the inner core is solid at 10,800 fahrenheit, but its not a liquid because of the pressure on the inner core.
