<human>:  Where does the Gulf Stream start?
<bot>: The Gulf Stream starts in the North Atlantic, off the coast of Newfoundland. It then flows southward through the Atlantic Ocean, eventually reaching the Gulf of Mexico. It is powered by the difference in temperature between the warm surface waters of the Gulf Stream and the cold water of the North Atlantic. The Gulf Stream is a very strong current, and it is responsible for transporting a lot of warm water into the North Atlantic, helping to regulate the global climate.
