Question 5 • Fall 24 GSE Physical Science B IC

Which statements accurately describe Earth’s 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 Earth’s geographic poles. The magnetic field is generated in Earth’s core.The magnetic field is similar to the magnetic field of a bar magnet.

Answer
A
The magnetic field lines flow from Antarctica to northern Canada.
B
The magnetic field is created by magnetic rocks on the surface.
C
The magnetic poles line up exactly with Earth’s geographic poles.
D
The magnetic field is generated in Earth’s core.
E
The magnetic field is similar to the magnetic field of a bar magnet.

Explanation

Earth’s magnetic field is generated by moving molten metal in its outer core, so D is correct. Its overall pattern resembles the field around a bar magnet, making E correct. Outside Earth, the field points approximately from Antarctica toward northern Canada, so A is also correct. The field is not produced by surface rocks, and its magnetic poles do not line up exactly with the geographic poles.
