about 1,200 km
1220 km thick
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
inner core is the earths center .
The radious of the inner core is 1,220km(760miles).
the thickness of each part is the mantle, the inner core, and inner core
i don't know the answer!
The inner core Is solid and the outer core in liquid
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
The earth's inner core is 3160 kilometers beneath the earths surface. The inner core is a solid ball of nickel-iron alloy.
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.
