How do geologists interpret unseen deep ocean currents?
What will be an ideal response?
Answer: Combining field observation of rocks and modern processes with laboratory experiments revealed that certain graded sandstone beds interlayered with deep-water marine shale are the result of turbidity currents. Turbidity currents are mixtures of sediment and water that are denser than clear water and rush along the seafloor or lake bottoms. Solving some geologic problems requires integrating modern field observation and laboratory experimentation with study of ancient rocks and modern processes.
