The innercore of the earth’s crust is the innermost part and is
primarily solid in form, made of metal.
It is the hottest part of the earth and is believed to be just as hot as
the sun’s surface.
The outercore of the earth’s crust is next to mantle, but, this
part is liquid in form. The outercore is
sometimes called the “liquid core”. It
is believed that this core is made up of liquid metal. Sulfur and oxygen could also be present in
this part of the earth.
