What is the scientific name for waterfalls?

Waterfalls do not have a specific scientific name as they are not a biological organism. Instead, they are classified as geological features or landforms. Waterfalls are formed by the erosion of rock layers, and their study falls under the field of geomorphology. While individual waterfalls may have names, such as Niagara falls, there is no overarching scientific nomenclature for the phenomenon itself.
