Question

Many of the organisms that thrive in the intertidal zone attach to surfaces or hide in crevices. Which oceanic process is most related to the need for these adaptations?

The changes in water level due to the tides cause the level of salinity to change daily.
The force of waves pulling on the shoreline can carry organisms into the open ocean.
The high tide increases water depth, and some intertidal organisms cannot swim.
The thermohaline ocean current patterns cause surface water and organisms to sink.

Answer 1

I think the correct answer would be the second option. The oceanic process that is most related to these adaptations would be that the  force of waves pulling on the shoreline can carry organisms into the open ocean. The intertidal zone is the zone where it is above the water during low tides and under the water when high tides. It is known as the seashore. Organisms that live here would tend to hide and attach to the surfaces because they could be washed off to the deeper parts of the ocean if they don't wherein they could not survive.
