Question

which statements accurately describe earths magnetic field? check all that apply. the magnetic field lines flow from antarctica to northern canada. the magnetic field is created by magnetic rocks on the surface. the magnetic poles line up exactly with earths geographic poles. the magnetic field is generated in earths core. the magnetic field is similar to the magnetic field of a bar magnet.

Explanation:

• Earth's magnetic field lines flow from the south - magnetic pole (near Antarctica) to the north - magnetic pole (near northern Canada).
• The magnetic field is generated by the motion of molten iron in Earth's outer core, not by magnetic rocks on the surface.
• The magnetic poles do not line up exactly with the geographic poles; there is a magnetic declination.
• The magnetic field is generated in Earth's core due to the dynamo effect.
• Earth's magnetic field is similar to that of a bar magnet with a north and south magnetic pole.

Answer:

The magnetic field lines flow from Antarctica to northern Canada.
The magnetic field is generated in Earth’s core.
The magnetic field is similar to the magnetic field of a bar magnet.
