Question

a compass taken to earth’s moon does not point in a specific direction on the moon. what is the most likely reason for the difference between how the compass works on earth and on the moon? the moon lacks an atmosphere. the moon contains no rocks that have iron. the moon does not have a strong magnetic field. the moon has no bodies of water.

Explanation:

A compass works by aligning with a magnetic field. Earth has a strong magnetic field, so a compass points north - south. The moon does not have a strong magnetic field, so a compass on the moon doesn't point in a specific direction. The moon lacking an atmosphere (option 1) or bodies of water (option 4) has no relation to how a compass works. Also, the moon does have rocks with iron (so option 2 is incorrect).

Answer:

C. The moon does not have a strong magnetic field.
