Roughly 1216 kilometers.
The inner core has a radius of 1220 kmA extending from the centre of the Earth approximately 6370 km below Earth's surface to 5150 km below the surface (the change from inner to outer core is marked by a density change known as the Lehmann discontinuity). The inner core has a total volume of 7.4207x109 km3.
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
inner core and outer core
Roughly 1216 kilometers.
Inner core
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter

There are two parts to core at the center of the Earth.the outer core is made of liquid iron and nickel and the inner core is made of solid iron and nickel.The inner core is solid from all off the pressure pushing down on it.
Inner layer? Like the most middle? I think the inner core.
a inner core is a dense ball of solid metal a outer core is a layer of molten metal surrounding the inner core
The outer core of the Earth.
Crust, mantle, outer core, inner core
The inner core is a dense ball of solid metal the outer core is a layer of molten matel that surronds the inner core.
