Turbidity currents are propelled by the water within them. Indicate whether the statement is true or false
ANS: F
Turbidity currents are actually propelled by gravity. The mass movement of sediments occurs when
turbulence mixes sediments into the water above a sloping bottom. The sediment then flows down the
slope, sometimes at great speeds due to the gravitational pull. Information can be found in the section
Continental Margins May Be Active or Passive.
