Gold is found underground and in rivers. It can be found in its pure form like a gold nugget. Gold can be used for jewelry, coins, and dental work (crowns).

Interesting Facts

I think it is interesting that gold can be used to treat cancer, especially bladder, cervix, and prostate.

It is also interesting that it is used in space helmets and satellites because it is a great shield for radiation.
