Slump and creep geology
WebbCreep is the culprit [source: United States Geological Survey]. In slump, a large segment of sediment breaks off in one piece rather than in lots of segments. It occurs when the base can no longer support the weight of what's on top. The sediment involved in slump is usually wet or claylike, and water is often the factor that causes it to fall.
