A Class 10 waterfall using this scale is Inga Falls, Democratic Republic of Congo, where the Congo River twists in a series of rapids. Some scientists classify waterfalls based on the average volume of water in the waterfall. There is not a standard way to classify waterfalls. An earthquake, landslide, glacier, or volcano may also disrupt stream beds and help create waterfalls.

A waterfall may form across a fault, or crack in the Earth’s surface. The waterfall erosion process starts again, breaking down the boulders of the former outcropping.Įrosion is just one process that can form waterfalls. This causes the waterfall to 'recede' many meters upstream. The resulting erosion at the base of a waterfall can be very dramatic, and cause the waterfall to ' recede.' The area behind the waterfall is worn away, creating a hollow, cave-like structure called a 'rock shelter.' Eventually, the rocky ledge (called the outcropping) may tumble down, sending boulders into the stream bed and plunge pool below. The crashing flow of the water may also create powerful whirlpools that erode the rock of the plunge pool beneath them. Rushing water and sediment topple over the waterfall, eroding the plunge pool at the base. The movement of water at the top of a waterfall can erode rocks to be very flat and smooth. Waterfalls develop as these granite formations form cliffs and ledges.Ī stream's velocity increases as it nears a waterfall, increasing the amount of erosion taking place. Eventually, the stream's channel cuts so deep into the stream bed that only a harder rock, such as granite, remains. Sediment can erode stream beds made of soft rock, such as sandstone or limestone. The sediment can be microscopic silt, pebbles, or even boulders. Many waterfalls in an area help geologists and hydrologists determine a region's fall line and underlying rock structure.Īs a stream flows, it carries sediment. In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.Ī fall line is the imaginary line along which parallel rivers plunge as they flow from uplands to lowlands. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). Often, waterfalls form as streams flow from soft rock to hard rock. Waterfalls themselves also contribute to erosion.

The process of erosion, the wearing away of earth, plays an important part in the formation of waterfalls.

A waterfall is a river or other body of water's steep fall over a rocky ledge into a plunge pool below.
