All of Earth’s marine waters are interconnected, forming a single continuous body of salt water that covers approximately 71% of the planet’s surface.

However, for ease of navigation, study, and mapping, this massive body is traditionally divided into distinct named regions. The Traditional Four how many oceans are there

The creates a distinct ecological and biological boundary around the continent of Antarctica. Because the water within this current is colder and less salty than the waters to the north, scientists argued it deserved its own classification.

Consequently, some educational systems still teach four, while others—and most modern scientists—teach five. Conclusion This "World Ocean" is critical for regulating global
