Itâs clear that in order to have the current balance of elements that Earth has further up, the core must be 85 percent iron and 10 percent nickel. That has meant that 5 percent of it has remained up for grabs, so to speak, to anyone who can come up with a convincing enough theory.
Outer Core The inner part of the earth is the core. This part of the earth is about 1,800 miles (2,900 km) below the earth's surface. The core is a dense ball of the elements iron and nickel.It is divided into two layers, the inner core and the outer core. The inner core-the center of earth-is solid and about 780 miles (1,250 km) thick.he outer core is so hot that the metal is always molten. The outer core is about 1,370 miles (2,200 km) thick. Because the earth rotates, the outer core spins around the inner core and that causes the earth's magnetism. The outer core is at 1,800 - 3,200 miles (2,890-5,150 km) below the earth's surface.
