- Water deposits the leaves at the foot of the hill and fans out
- A delta is formed by sediment depositing at the mouth of a river by water fanning out
- Therefore, water depositing leaves at the foot of the hill is similar to water forming a delta

Therefore, water depositing leaves at the foot of the hill is similar to water forming a delta
During a rainstorm, leaves wash down a gully on a hillside. The water slows down at the foot of the hill and fans out, depositing the leaves. What geologic structure is formed in a similar way?
