1220 km thick
The thickness of the inner core is 500km
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
the inner core is NOT made from rock.?!
the inner core is a solid
the solid inner core and the liquid outer core
No. The combined thickness of the inner and outer core is about 3500 to 3520 kilometers, out of the Earth's total radius of about 6370 kilometers. This means that the combination of inner solid core and liquid outer core has about 16% of the Earth's volume. *The reference to "1% of the Earth's volume" may refer to the Earth's crust, which has about "1% of the Earth's total mass."
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 thickness of each part is the mantle, the inner core, and inner core
i don't know the answer!
About 760miles thick.
about 1,200 km
in the outer core it has a 6960 km.While the inner core is about 2440 km. in diameter
It is 1300km and consists of mainly iron and nickel.
the thickness of the outer core is 2250 km.
The outer core is 2300 kilometers thick. It is composed of mainly nickel and iron. The inner core is 1200 kilometers thick and composed of iron.
The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.
