Mercury's average density and the fact that it has a (weak) magnetic field lead to the conclusion that its central core is probably composed of

Question

Quizplus · Accepted Answer

Mercury's high average density suggests a large metallic core, and its magnetic field indicates this core is at least partially molten, allowing for the generation of the field through dynamo action. Iron is the best candidate for this core composition due to its density and magnetic properties.
