weathering-limited slope

A weathering-limited slope is a geological feature where the rate of debris removal by transport processes exceeds the rate at which new debris is generated by weathering. This results in a distinct morphology, often characterized by an upper free face or cliff that contributes material to a lower slope of accumulation. These slopes are commonly found on bare rock, and their profile is primarily determined by the rock's resistance rather than the erosional forces acting upon it. Consequently, rock slopes may retreat parallel to themselves, maintaining a consistent angle for a given rock type's strength. This contrasts with transport-limited slopes, where weathering produces debris faster than it can be removed, leading to a soil-covered slope with a different profile. Weathering itself is the disintegration or alteration of rock at or near the Earth's surface through physical, chemical, and biological processes.12
