Which term is used for a series of events that occur as a result of one initial event?

The term "chain reaction" is used to describe a series of events that occur as a direct result of one initial event. In this context, when one event triggers subsequent events in a sequence, it creates a cascading effect where each event is related to the initial cause. This term is often used in various fields such as chemistry, physics, and even in social scenarios, illustrating how one action can lead to a continuous chain of reactions or occurrences.

The other options, while related to cause and effect, represent different concepts. "Cause and effect" describes a broader relationship where one event (the cause) leads directly to another (the effect), but does not necessarily imply a series of subsequent events. The "domino effect" also illustrates a chain of reactions but is typically used in more metaphorical contexts where one small change leads to larger consequences. A "feedback loop," on the other hand, refers to a process where the output of a system influences its own input, which can stabilize or destabilize the system but does not inherently imply a linear sequence of events.
