Answer:
Continental shelf - the territory of seabed around an enormous landmass where the ocean is moderately shallow contrasted and the untamed sea. The mainland rack is topographically part of the mainland hull.
Subtidal Zone- Where the water is generally liberated from suspended particles, daylight can enter the water surface to a profundity of more than 100 feet. Shallow subtidal networks in this photosynthetic zone might be ruled by thick collections of kelp in certain zones.
