Question

The subtidal zone is the area:

a) Between low and high tide.
b) Beyond the continental shelf.
c) Between the intertidal zone and the edge of the continental shelf.
d) Where pelagic organisms live.

Answer 1

The subtidal zone is the area between the intertidal zone and the edge of the continental shelf, always submerged and home to diverse marine life.

Step-by-step explanation:

The subtidal zone is the area described as the oceanic region that extends from the outer margin of the intertidal zone - the area between high and low tide that includes sandy beaches, rocky shores, and muddy flats - to the edge of the continental shelf. The correct answer to the student's question is that the subtidal zone is between the intertidal zone and the edge of the continental shelf. This zone is constantly submerged in water and supports a variety of marine life due to its stable conditions and abundance of light in its upper layers, enabling photosynthesis to occur.
