What is another word for chain reaction?
Pronunciation: [t͡ʃˈe͡ɪn ɹɪˈakʃən] (IPA) 
Chain reaction, a term commonly used in chemistry and physics, describes a process where a single event triggers a series of reactions. It is an essential phenomenon in nuclear reactions and explosions. However, several words and phrases can be used to describe the same phenomenon, including domino effect, snowball effect, ripple effect, and knock-on effect.
The domino effect describes a situation where one event sets off another, which in turn sets off another, much like a falling line of dominoes. The snowball effect is similar, where a small change leads to a series of significant shifts, like a small snowball rolling and growing as it moves downhill. The ripple effect is more metaphorical, where one event causes several consequences that spread out like ripples in a pond. Finally, the knock-on effect suggests a situation where a direct impact causes multiple subsequent impacts.
