Question

Quizplus · Accepted Answer

Both the Moon and Mercury have cores that are more iron-rich than the rest of the body, and they both have a solid inner core and fluid outer core. Additionally, both cores are relatively large in proportion to the size of the body. Choice A is incorrect because the cores are not solid throughout. Choice B is incorrect because the Moon's core is not as large in proportion to the size of the body as Mercury's core. Choice D is incorrect because both cores have a solid inner core and fluid outer core, not the other way around. Both the Moon and Mercury have cores that are more iron rich than the rest of the body, and both have a solid inner core and a fluid outer core. However, there is no evidence to suggest that the cores are larger or smaller in proportion to the overall size of the object.
