Web6. what material make up the inner core Inner core is made up of solid, iron ,and nickel materials. 7. what materials make up the inner core? Answer: crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core's iron-nickel alloys is simply the elements' chemical symbols—NiFe. Web31 mrt. 2024 · Seismic measurements show that the core is divided into two parts, a “solid” inner core with a radius of ~1,220 km and a liquid outer core extending beyond it to a radius of ~3,400 km.
