Homonym: cascade (Waterfall)
A "cascade" refers to a series of events or processes that occur in a sequential manner, where each step triggers the next. This term is often used in various fields, such as biology, where a cascade of biochemical reactions can lead to a significant change in a cell's function.
In a more physical sense, a cascade can describe a waterfall that flows over a series of rocks or ledges, creating a beautiful and dynamic display of water. This natural phenomenon can be found in many locations, such as the Niagara Falls or the Yosemite National Park.
