How do elements like gold, copper, and lead end up on earth?

• they flow through sunshine to the earth

• as the earth gets close to a red giant, its gravity pulls these elements to the ground

• supernovae send these elements into the interstellar matter and they end up on earth from there

• these elements are made on earth by volcanic action
