<P> A turbidity current is most typically an underwater current of usually rapidly moving, sediment - laden water moving down a slope . Turbidity currents can also occur in other fluids besides water . </P> <P> In the most typical case of oceanic turbidity currents, sediment laden waters situated over sloping ground will flow down - hill because they have a higher density than the adjacent waters . The driving force behind a turbidity current is gravity acting on the high density of the sediments temporarily suspended within a fluid . These semi-suspended solids make the average density of the sediment bearing water greater than that of the surrounding, undisturbed water . </P>
