Which marine zone extends from the low tide line to the edge of the continental shelf?

Which marine zone extends from the low tide line to the edge of the continental shelf?

• A. Pelagic Zone
• B. Littoral Zone
• C. Neritic Zone
• D. Bathyal Zone

Answer: (C)

Understanding how the ocean is divided by distance from shore and depth helps here. The Neritic Zone refers specifically to the coastal waters that lie above the continental shelf, extending from the low tide line out to the edge of the shelf. This zone is shallow and well-lit, supporting abundant coastal life such as coral reefs, seagrasses, and abundant plankton communities. In contrast, the Pelagic Zone covers open water away from the bottom, the Littoral Zone is the intertidal strip along the shore between high and low tides, and the Bathyal Zone lies on the continental slope at greater depths. So, the zone that matches the description of reaching from the low tide line to the shelf edge is the Neritic Zone.
