Where did the materials that make up earth originally come from?

this is due by friday. Thanks!Where did the materials that make up earth originally come from?
The heavier elements were made in a supernova or ';hypernova.';Where did the materials that make up earth originally come from?
They came from stars. Iron, of which our planet has a high percentage, is made in the core of a yellow star like ours, a product of fusion- first hydrogen to helium, then helium to the heavier elements.
