A cascade is a series of waterfalls or a flow of water that falls from a height, often creating a beautiful and dynamic natural feature. Cascades can be found in various environments, including mountains and forests, and are formed by the erosion of rock and soil over time. They can vary in size, from small trickles to large, powerful falls. In addition to natural cascades, the term can also refer to a sequence of events or processes that occur in a chain reaction. For example, in technology, a cascade might describe how one change leads to another, similar to how a domino effect works.
