Which description best matches Earth's magnetic field lines?

• A. The field lines go out of Earth near Antarctica, enter Earth in northern Canada, and are aligned with the geographic poles.
• B. The field lines go out of Earth near Antarctica, enter Earth in northern Canada, and are not aligned with the geographic poles.
• C. The field lines go out of Earth in northern Canada, enter Earth near Antarctica, and are aligned with the geographic poles.
• D. The field lines go out of Earth in northern Canada, enter Earth near Antarctica, and are not aligned with the geographic poles.

Answer: (B)

Earth’s magnetic field behaves like a tilted dipole: field lines emerge from the magnetic south pole near Antarctica and loop around to enter the magnetic north pole near northern Canada. They are not perfectly aligned with the geographic poles because the magnetic dipole axis is tilted relative to the Earth's rotation axis, and the magnetic poles are offset from the geographic poles.

So the description that matches is: field lines go out near Antarctica, enter near northern Canada, and are not aligned with the geographic poles. The other options either reverse the direction or claim alignment with the geographic poles, which doesn’t hold true due to the tilt and offset of the magnetic poles.
