Question

part 2: horizontal zonation (distance from shore)
day 3 focus: the continental shelf and open sea
horizontal zones are determined by the proximity to land and the depth of the ocean floor
beneath the water.

1. label and define the zones:

• intertidal zone:

• neritic zone:

• oceanic zone:

Explanation:

1. Intertidal Zone: This is the shoreline zone between high and low tide marks, so it is alternately submerged and exposed to air as tides shift.
2. Neritic Zone: This is the shallow ocean zone extending from the low tide mark to the edge of the continental shelf, with relatively shallow, sunlit waters.
3. Oceanic Zone: This is the deep, open ocean area beyond the continental shelf, making up the majority of the ocean's volume.

Answer:

• Intertidal Zone: The coastal zone between high and low tide, alternately covered and exposed by ocean waters.
• Neritic Zone: The shallow ocean region from the low tide line to the continental shelf edge, with depths generally less than 200 meters.
• Oceanic Zone: The vast, deep open ocean area that lies beyond the continental shelf, including the ocean's deepest regions.
