What is it that maintains and keeps the earth's core heated up?
Hi there! You can think about this in terms of all the energy that was involved for the formation of planet Earth. A lot of heat was created during this process but not a lot of it has been lost so far. In fact, the earth's core is cooling down and because of that it is becoming more and more solid! There are other reasons for Earth's temperature but that is the main one, according to Scientific American (trustworthy). Maybe you'd want to know: the Earth's core consists of two parts: the inner core, which is solid, and the outer core, which is liquid (more like honey-style liquid).
