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:

The Earth's magnetic - field is generated by the motion of molten iron and nickel in the outer core (dynamo effect). The rotation of the Earth on its axis helps organize and sustain this motion. Surface weather, metal liquefying in the inner core (it's solid), Earth's revolution around the Sun, and rock solidifying in the outer mantle do not contribute to the formation of the Earth's magnetic field.

Answer:

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