Question

which phenomena help form earths magnetic field? check all that apply. weather on earths surface rotation of earth on its axis metal liquifying in the inner core revolutions of earth around the sun rock solidifying in the outer mantle motion of metal in earths outer core

Explanation:

Earth's magnetic field is generated by the geodynamo effect: the rotation of Earth on its axis drives the convective motion of the liquid, conductive metal (iron-nickel) in the outer core, creating electric currents that produce the magnetic field. Surface weather, orbital revolution around the Sun, inner core metal liquefaction, and outer mantle rock solidification do not contribute to forming this field.

Answer:

• rotation of Earth on its axis
• motion of metal in Earth's outer core
