A) Pelagic sediments B) Neritic sediments _____ 15) __________ are found primarily on the continental slope and rise and deep ocean basins. Pelagic sediments are commonly more fine-grained than neritic sediments. Ample solar radiation keeps the water relatively warm compared to deeper layers, and temperatures remain stable. Marine sediments can either be neritic or pelagic. The relative abundance of each depends upon the nature of the local drainage basin, the climate, and the relative age of a lake. The neritic zone supports numerous habitats and hosts a wealth of marine species, making it a critical region from an ecological standpoint, as well as an economic standpoint. Because of the depths it can reach, the benthic zone is often characterized by low sunlight and low temperatures (Alldredge 1988). Early to middle Eocene neritic sediments show evidence of being less restricted as reflected by pervasive, well-developed sediment bioturbation and increasing abundance of calcareous nannofossils.
