<human>:  What is the difference between a riot and a rebellion?
<bot>: The key difference between a riot and a rebellion is that a riot is a violent outburst of anger, usually involving a large group of people, whereas a rebellion is an organized and sustained effort to oppose or remove an established authority. A riot typically occurs spontaneously and is often considered a form of civil disorder, while a rebellion may involve military power and is viewed as an organized resistance or attempt to overthrow the existing government or leadership.
