Answer :
Final answer:
The open-ocean zone is divided into the intertidal zone, neritic zone, and oceanic zone, distinguished by their proximity to shore and depth.
Explanation:
The three zones that further divide the open-ocean zone are the intertidal zone, the neritic zone, and the oceanic zone. The intertidal zone is located between the high and low tidal marks and is subject to the changing conditions of tides and waves. The neritic zone lies beyond the intertidal zone, extending from the low tide mark down to the edge of the continental shelf, where some sunlight can still penetrate the seabed. The oceanic zone includes the rest of the ocean beyond the neritic zone and encompasses regions where sunlight does not reach the bottom.
Moreover, each of these oceanic zones supports distinct ecosystems and marine life adapted to the specific environmental conditions, such as varying light levels, nutrient availability, and water pressure. The delineation of these zones aids marine scientists in studying the diverse habitats and biodiversity found in different layers of the open ocean.
Final answer:
The three zones that further divide the open-ocean zone are deep zone, surface zone, transition zone.
Explanation:
The correct answer is deep zone, surface zone, transition zone.
The open-ocean zone, also known as the pelagic zone, is divided into three zones: the epipelagic zone (surface zone), the mesopelagic zone (transition zone), and the bathypelagic zone (deep zone).
The surface zone is the top layer of the open-ocean zone where sunlight can penetrate and where most marine life is found. The transition zone is the middle layer that acts as a boundary between the surface zone and deep zone. The deep zone is the bottom layer of the open-ocean zone that extends to great depths.
