Oceans are divided into what general units?

Oceans are divided into what general units?

• A. Zones
• B. Layers
• C. Regions
• D. Compartments

Answer: (A)

Oceans are divided into broad zones to describe areas with shared characteristics, such as depth, light availability, and distance from shore. This approach lets scientists talk about how conditions change from near the coast to open water and from the surface to the deep. The term zones covers both horizontal regions (coastal, neritic, and oceanic) and vertical ones (photic, disphotic, and aphotic) under a single, flexible framework, making it the most useful general unit for describing marine environments. Layers focus more on physical strata, regions is a broader, less precise term, and compartments implies separate, closed sections, which isn’t how ocean divisions are usually described.
