The thickness of the inner core is 1,200 km. 1,200 km being the radius of the sphere known as the inner core.
the inner part of earths core
The radious of the inner core is 1,220km(760miles).
The inner core Is solid and the outer core in liquid
the thickness of each part is the mantle, the inner core, and inner core
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
The immense pressure from the layers outside of the inner core.
iron and nickel is the answer and so is the inner core. the inner and the outer and together but the outer core is liquid and the inner core is solid
About 760miles thick.
The solid inner and liquid outer core.
About 2100 km.
