The Earth's core is made up of very heavy material mostly constituted by:

  • A.Iron and Aluminum
  • B.Aluminum and Nickel
  • C.Nickel and Iron
  • D.Nickel and Lead

Answer: C

The core is chiefly nickel and iron.

It is often called the NiFe zone for that reason. The outer core is liquid and its convection generates the earth's magnetic field; the inner core, under still greater pressure, is solid despite being hotter.
