Strawberry, Raspberry and Rhubarb Crisp | completelydelicious.com

All three are very similar, with a bottom of fruit and top comprised of some sort of pastry. A cobbler has a biscuit topping on top of the fruit. The biscuits are dropped on individually and as they bake they form a bumpy surface like cobblestones, hence the name. Crisps and crumbles are very similar— fruit under a streusel-like topping. The difference is that crisps typically have oats and crumbles do not.
