Final answer:
Eddies form at the boundary of the Gulf Stream and develop into warm-water rings that move into colder zones, affecting the climate and marine ecosystems.
Step-by-step explanation:
Eddies form at the western boundary of the Gulf Stream, increasing in amplitude as they move downstream. The current pinches off the curve, forming a warm-water ring that wanders into the cold-water zone.
These features result from the interaction between the warm waters of the Gulf Stream and the surrounding colder waters, leading to dynamic oceanographic phenomena that can influence local climate and marine life.
