genetic drift: changes in gene frequencies from generation to generation in a *small* population as a result of random mating
gene flow: migration of individuals between populations that allow for more genetic variability during breeding

One is just an influx of organisms mating within a new population. The other is a sampling error. Now, get out your book, to fill this explanation out.
