Worms, Sidewalks, and Dirt

A reader recently asked us an interesting question about worms on the sidewalk. The subject matter isn’t strange – lots of people wonder why worms come out on the sidewalk – but his focus was unusual. He wasn’t curious about the presence of the worms, but rather about the “black balls of dirt” that came along with them onto the sidewalk. The reader asked “what” he was finding, which seems fairly simple – black balls of dirt (or possibly worm castings) – so we suppose we should expand the scope of the question, covering the matter of why he is finding dirt on the sidewalk along with worms.
