Question

Which of these is the most likely reason why the auroras Are sometimes seen at northern Ohio although it is at a much lower latitude than the North Pole?
A. The solar winds change their direction constantly

B. The magnetic north and south poles are interchanged constantly

C. The magnetic field of earth keeps changing because of the suns activity

D. The strength of the bar magnet inside earth changes because of lunar activity

Answer 1

Answer:

The correct answer is option C. "The magnetic field of earth keeps changing because of the suns activity"

Explanation:

The magnetic field of Earth is not a steady force, and is affected by external forces such as the suns activity, particularly during strong solar/geomagnetic storms. The changes in the magnetic field of Earth explains why the auroras Are sometimes seen at northern Ohio. The auroras are created by energetic electrically charged particles accelerating along the magnetic field, if the location of the magnetic filed changes, the location of the auroras change as well.
