Final answer:
A smoldering crisis is the type of crisis that starts small and can grow into a larger problem if not addressed, contrasting with a sudden crisis that is immediate and obvious.
Step-by-step explanation:
The type of crisis that starts off small and then begins to grow into a larger crisis is known as a smoldering crisis. Unlike a sudden crisis, which strikes without warning and is immediately apparent, a smoldering crisis begins as a minor issue that may not be immediately noticed. Over time, if not addressed, it can escalate into a major problem. For example, a small customer complaint that is ignored could snowball into a large-scale customer backlash, damaging the company's reputation and financial standing.
