What is the connection between comets and the Kuiper belt? between comets and the Oort cloud?

Question: Explain the connections between comets and the Kuiper Belt, as well as comets and the Oort Cloud. Answer: The connection between comets and the Kuiper Belt lies in the origin of short-period comets, which come from the Kuiper Belt's numerous icy bodies that can be perturbed by gravitational interactions, causing their orbits to change and bring them into the inner solar system as comets. On the other hand, the connection between comets and the Oort Cloud is related to the origin of long-period comets, which are believed to originate in the Oort Cloud. Gravitational interactions with nearby stars or other objects in the galaxy can perturb the orbits of icy bodies in the Oort Cloud, sending them into the inner solar system as long-period comets.
