<human>:  What is the difference between a stock market dip and a crash?
<bot>: The difference between a stock market dip and a crash is that a dip typically refers to a short-term decline in the stock market while a crash refers to a sudden, catastrophic plunge in the stock market that lasts for an extended period of time. A dip is usually a sign of market volatility within a single day, whereas a crash is a much more dramatic and prolonged decline.
