Question

what fact about the magnetic field of mercury was unexpected? mercury actually has a magnetic field. it is comparable to the magnetic field of jupiter. it is the strongest of the magnetic fields of the terrestrial planets. which statement is the major reason the magnetic field of mercury has this unexpected property? the elliptical orbit of mercury contributes to its magnetic field. an outer shell of mercurys core remains molten. the solar wind from the nearby sun contributes to mercurys magnetic field.

Explanation:

Mercury is a small planet, and it was unexpected to find that it has a magnetic - field. Planets generate magnetic fields through a dynamo effect which requires a liquid - conducting core. For Mercury, an outer shell of its core remaining molten allows for the generation of its magnetic field.

Answer:

1. Mercury actually has a magnetic field.
2. An outer shell of Mercury's core remains molten.
