Cascading waterfalls are natural formations where water flows over a vertical drop or cliff, creating a series of steps or tiers. These waterfalls can vary in size and shape, often resulting from the erosion of rock over time. The water cascades down, creating a beautiful and dynamic display of nature. These waterfalls are commonly found in mountainous regions and can be part of larger river systems. They play a crucial role in the ecosystem by providing habitats for various species and contributing to the water cycle. Famous examples include Niagara Falls and Angel Falls.
