How would the inner core change, or be different, if it was made out
... If the inner core was made out of bubble gum, rather than iron, this is what I think would happen. First of all, the Earth would have no magnetic poles because iron is magnetic and causes the poles. Gum is not magnetic. Thus, there would be no poles. If we did not have any magnetic poles, no compass ...
