❓ Frequently Asked Questions
What is the World Ocean?
The World Ocean is the interconnected system of Earth's saltwater oceans—the Pacific, Atlantic, Indian, Southern, and Arctic—that together form one global body of seawater.
How much of Earth's surface is covered by oceans?
About 71% of the Earth's surface is covered by oceans.
What does seawater salinity mean and what is its typical value?
Salinity measures dissolved salts in water; ocean water averages about 35 parts per thousand (3.5%), with local variations.
What are the main vertical zones in the ocean?
The ocean has sunlit and dark zones. Depth-based divisions include epipelagic (0–200 m), mesopelagic (200–1,000 m), bathypelagic (1,000–4,000 m), and abyssopelagic (4,000–6,000 m); the photic zone refers to the sunlit part.
What are common threats to ocean health?
Overfishing, plastic and chemical pollution, warming and acidification from climate change, and destruction of habitats like coral reefs.
