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:

• Weather on Earth's surface has no relation to the formation of the magnetic field.
• The rotation of Earth on its axis is part of the dynamo effect that helps generate the magnetic field.
• The inner core is solid, not liquifying.
• Revolutions of Earth around the Sun are related to seasons etc., not the magnetic field.
• Rock solidifying in the outer mantle is not involved in magnetic field formation.
• The motion of metal (liquid iron - nickel) in Earth's outer core is crucial for the dynamo effect that forms the magnetic field.

Answer:

rotation of Earth on its axis, motion of metal in Earth’s outer core
