5.7 How do we know how to interpret unseen turbidity currents?

• Field observations of rocks and processes with laboratory experiments have revealed that graded sandstone beds interlayered with marine shales come from rapidly moving currents.
• Turbidity currents are mixtures of sediment and water denser than the clear water above, that hug the bottom as they move.
• Solving some geologic problems requires integrating studies of ancient rocks and modern processes.
