Construct an explanation for why the physical properties of the inner core, outer core, and lower mantle are essential for the development of Earth's magnetic field.

The hot temperature of inner core and outer core is responsible for the production of magnetic field.

Explanation:

The physical properties of the inner core, outer core, and lower mantle are essential for the development of Earth's magnetic field because the very high temperature of inner core is responsible for the formation of magnetic field. If the inner core is not very hot so the magnetic field will not be generated and our earth's atmosphere will not be save from the solar wind. It can be blown away by the solar wind if this magnetic field is not present so we can conclude that the physical properties of inner core and outer core is important for the production of magnetic field.
