The term "turbidity current" is most commonly used to describe underwater currents in lakes and oceans, which are usually triggered by Earthquake s or Slumping . In such cases, high-speed sediment-laden water flows down the slope under the clearer water, causing a great deal of Erosion and subsequent Sedimentation . Turbidity currents are characteristic of areas where there is seismic instability and an underwater slope, especially Submarine Trench slopes of convergent plate margins and continental slopes and Submarine Canyon s of passive margins. As the slope of the flow increases, the speed of the current increases. As the speed of the flow increases, turbulence increases, and the current draws up more sediment. The increase in sediment increases the density of the current, and thus its speed, even further. Turbidity currents can reach speeds up to half the speed of sound. Turbity currents are examples of Gravity Current s. EXAMPLES OF TURBIDITY CURRENTS
