Why is the centre of the Earth so hot?

the core of the earth is as hot as the

surface of the Sun and there's really

two reasons why there's so much heat in

the center of the earth

the first reason is that when the earth

was formed it was bombarded with larger

and larger pieces of rock and the energy

of those collisions was stored as heat

energy in the Earth's core

and the second reason is that much of

the elements that make up the core of

the earth are radioactive and so when

they undergo radioactive decay they

release large amounts of energy


so they're the two reasons why the

center of the earth is so hot
