What is a word that means small pieces coming together to make a big thing?

I'm looking for a word like "snowballing".

  • Coalesce, unite, join together, combine, merge, fuse, mingle, meld, blend, intermingle, knit (together), amalgamate, consolidate, integrate, affiliate, link up, homogenize, synthesize, converge. (Just from one quick Google.)
