WebTerraces are nearly ubiquitous features of river valleys that attest to a fundamental unsteadiness in the rate of vertical incision. The most common sources of that unsteadiness are vegetative, geomorphic, and hydrologic responses to climate, which for the Quaternary, are characterized by 100-ky glacial–interglacial cycles.
