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.
