oceans
Continent-separating waters
Oceans are the vast bodies of salt water covering most of Earth's surface—the Pacific, Atlantic, Indian, Arctic, and Southern.
The word often appears in the singular to mean this water collectively: the ocean, ocean currents.
Figuratively, an ocean of something is an immense quantity: oceans of time, an ocean of paperwork.
