It starts at the shoreline and continues down until it reaches the floor, encompassing the sediment surface and sub- surface layers. D) silt. Neritic waters are penetrated by varying amounts of sunlight, which permits photosynthesis by both planktonic and bottom-dwelling organisms. For example, beach rocks from a barrier island may grade into lagoonal rocks which can grade into delta deposits.
