What are the two fundamental physical characteristics of the continental shelf that affect subtidal organisms?
The two physical characteristics of the continental shelf that affect subtidal organisms are its relatively shallow depth and its proximity to land. 54. How does temperature variability on the continental shelf affect subtidal organisms? Because of its shallow depth, temperature varies from place to place in the subtidal zone, compared to the deep ocean. This is important because temperature is one of the most important factors determining the distribution of marine organisms. As a result, the kinds of organisms found in the subtidal zone vary tremendously from pole to equator. Additionally, there are many more individuals of any given species in the equatorial subtidal zone. 55. How do waves and currents on the continental shelf affect subtidal organisms? Because of its shallow depth, waves and currents have a much bigger impact in the subtidal zone than they do in the deep ocean. Tidal currents and wind waves affect the bottom, to depths of over 600 feet. They also prevent stratifica
