Answer:
The inner core makes up only 1% of the mass of the Earth; the outer core makes up about 32% of the mass of the Earth. Answer 2: The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid.
