Answer:

1) Our Earth's iron liquid outer core rotating around the solid inner core

Explanation:

The earth's magnetic field or the geomagnetic field is produced as a result of the earth's iron liquid outer core rotating around the solid inner core.

This produces the earth's magnetic field.

  • The earth's core is made up of solid and liquid region.
  • Only the densest elements are found within this region.
  • So, the core is made up of metals which are mainly iron and nickel.
  • The outer core is liquid or molten iron and the inner core is solid.
  • The molten iron and nickel in the outer core moves around the inner core and generates the currents which induces a magnetic field round the earth.
