You need to get a copy of the Periodic Table of the Elements. You can probably download a copy on the net; just Google it. So, OK: I think there's about 114 or so elements nowadays, but the first 92 of those elements are all naturally-occuring: they exist in nature! Despite what Matahari said, the others (after #92) are NOT natural; they are manmade.
So if by "earth's composition you mean the earth's crust and core, and not the atmosphere, just exclude the gases that are on the table, like hydrogen, nitrogen, neon, argon, etc. All the rest will be found in the earth itself. Most of them will be from the metal and matelloid families.

Tham153's answer was a good correction, but another element, promethium (At. No. 61) does not occur naturally, leaving 85 naturally occurring elements in the Earth.

All of them. What part of the Earth are you talking about?

If you mean solid, then virtually every metal on the periodic table.
