What sequence of events could account for the presence of relatively coarse sediment on the deep-ocean floor?
Why are quartz grains and clay particles the most common lithogenous sediments transported to the ocean by rivers and streams?
What is the significance of the carbonate compensation depth (CCD)? How might ocean acidification affect the CCD?
What would explain the near absence of sediment on some portions of the deep ocean floor?
Is the composition of biogenous sediment on the ocean floor always an indicator of the type of marine organisms living in the surface waters directly above? Explain your response.
