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, which relies on the conductive, molten metal in the outer core moving, combined with Earth's rotation. Surface weather, orbital revolution, inner core solidification (not liquefaction), and mantle rock solidification do not contribute to this field.

Answer:

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