Waterfalls are natural wonders that are formed by the erosion of bedrock and the hydraulic forces of water. The process of erosion is slow and depends on the shape of the waterfall, such as a horseshoe or a cascade. The process of potholing occurs when the waterfall creates a deep hole in the bedrock. Waterfalls form mostly in rivers while they are still young. Their channels are more narrow and deeper, which is the perfect setting for the formation of a waterfall. Waterfalls often start off as rapids, flowing over the hard rocks in the river bottom, while eroding the softer rocks. Due to them eroding slowly, the hard rocks get lifted above the stream bed. However, the speed of the erosion process is highly dependent on the strength of the river.
According to WorldAtlas, waterfalls typically form in young rivers because their channels are narrower and deeper than in established rivers. If the waterfall is shaped like a horseshoe, its erosion is focused on a specific point. The process of formation starts when the river flows through an area that is mostly made up of bedrock. This process is slow but is dominated by the impacts of water on the rocks. Downstream the process is more rapid and severe. The waters velocity increases the further downstream we go, and it is the highest at the edge of the waterfall. Once the water is there, it may pull out materials from the riverbed. At the bottom of the waterfall, the hydraulic forces are so strong that they are able to reach heights that allow them to erode the riverbed. The process of potholing occurs when turbulent whirlpools start to spin stones around the riverbed and create a deep hole in the bedrock due to erosion. This means that the sand and rocks that get carried by the river increase the capacity of the erosion .
National Geographic Society explains that often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls. The wearing away of earth plays an important part in the formation of waterfalls. The types, classification, and features of different waterfalls around the world are also discussed .
In summary, waterfalls are formed when a river or stream flows over a ledge or cliff, creating a stunning natural spectacle. The force of the water falling creates a hole in the rock behind it, called a plunge pool, and over time, the force of the water falling can erode the rock, creating a deep, narrow channel ..
