14. Juni 2024 · Ocean, continuous body of salt water held in enormous basins on Earth’s surface. There is one ‘world ocean,’ but researchers often separate it into the Pacific, Atlantic, Indian, Southern, and Arctic oceans. Covering nearly 71 percent of Earth’s surface, the oceans have an average depth of 3,688 metres (12,100 feet).
Vor einem Tag · The ocean's surface is an important reference point for oceanography and geography, particularly as mean sea level. The ocean surface has globally little, but measurable topography, depending on the ocean's volumes. The ocean surface is a crucial interface for oceanic and atmospheric processes.
Vor 19 Stunden · Atlantic Ocean, body of salt water covering about one-fifth of Earth’s surface and separating the continents of Europe and Africa to the east from those of North and South America to the west.
