What term describes a continuous body of salt water that is divided by landmasses?

The correct term for a continuous body of salt water that is divided by landmasses is an ocean. Oceans cover a significant part of the Earth's surface and are interconnected, making them vast bodies of water that are typically larger than seas and gulfs. They are characterized by their saltwater composition and depth, distinguishing them from lakes, which are freshwater bodies and generally smaller in size. While seas can also be considered connected to the ocean, they are usually partially enclosed by land and not as expansive. Gulfs, on the other hand, are smaller in scale and are often extensions of seas or oceans that are further inland, surrounded by land on three sides. Thus, when considering the definition of a continuous body of salt water divided by landmasses, ocean is the most accurate term.
