Ripple marks. Ripple marks are created by water moving across the surface of sediment, which then gets deposited. The ripples form as the water moves the sediment particles around and they eventually settle in the low areas between the ripples. The size and shape of the ripple marks can give scientists information about the speed and direction of the water flow.
