Structure of earth

What produces the heat at the centre of the earth?

nobody really knows, but it is probably due to a combination of magnetic fields and radioactivity.

The formation of the Earth.
Radioactive decay

It's from the Earth forming, the core is unlikely to be made from radioactive elements because it isn't dense enough. There's also the dynamo effect (which creates the magnetic fields) but Christ if this is expected to be known at GCSE and I obviously don't know how that affects heat created.

maybe nuclear reactions.

True.
I'm pretty sure at GCSE you only need to say Radioactive Decay - that's what I was taught in Geography.

Yeah 1 would be correct for the core but heat from radioactive elements more applies to the mantle and crust and because of how heat transfer works the heat from that would travel away from the core.
