The term "domino effect" refers to the sequence of events where one occurrence sets off a chain reaction. There are several synonyms that depict the same idea in different words. One synonym is the "ripple effect," which envisions the impact of a small disturbance that expands like waves in a pond. Another synonymous term is "chain reaction," which conveys a similar sense of events occurring as a result of one trigger. "Snowball effect" is another synonym that describes how a small action can gain momentum and grow into something more significant. Lastly, "cause and effect" encapsulates the same idea of one occurrence leading to another in a domino-like pattern.
