A. Geographic poles are defined by Earth's rotation.
The correct statement about Earth's poles is that magnetic poles are defined by Earth's rotation.
Explanation:The correct statement about Earth's poles is option B: Magnetic poles are defined by Earth's rotation.
Earth has two types of poles: geographic poles and magnetic poles. The geographic poles are the points where the Earth's axis of rotation meets the surface. On the other hand, the magnetic poles are the locations where the Earth's magnetic field is the strongest. The north magnetic pole is located near the geographic North Pole, and the south magnetic pole is located near the geographic South Pole.
Therefore, the Earth's south magnetic pole is not aligned with its geographic South Pole. The Earth's south magnetic pole is aligned with its geographic North Pole.
