Marine And Coastal Ecosystems Zones, Features, And Processes Practice Test

Which zone extends from the shoreline to the edge of the continental shelf, down to about 200 meters?

Neritic Zone Epipelagic Zone Benthic Zone Abyssopelagic Zone

Correct Answer:

Neritic Zone

Explanation:

In marine zonation, the Neritic Zone defines the coastal belt that sits over the continental shelf. It runs from the shoreline out to the edge of the shelf, down to about 200 meters. This makes it the correct choice because the description specifies a coastal zone bounded by the shelf edge, not the open-ocean water column or the seafloor. The Epipelagic Zone is the sunlit layer of open water and can occur over both shelf and open ocean, but it’s defined by depth rather than distance from shore. The Benthic Zone refers to the seafloor itself across depths, and the Abyssopelagic Zone is the deep-ocean layer far beyond the shelf. So the coastal belt from shore to shelf edge down to roughly 200 meters fits the Neritic Zone.
