What do ripple marks indicate?
Ripple marks are sedimentary structures and indicate agitation by water (current or waves) or wind. Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment.
What do ripple marks say about past environments?
Their crests are always oriented perpendicular to the current that formed them, telling us what the direction of currents in past environments was. Their shape, size and symmetry depend on the type of sedimentary process that is associated with their formation.
What do these ripple marks tell us about flow direction?
These types of ripple marks can tell you which direction the river was flowing because sediment moves up the shallow side of the ripple and gets deposited on the steep side (Figures 4.5 and 4.6).
Where are ripple marks formed?
Ripple marks formed by aeolian processes These occur in the upper part of the lower flow regime where sand with bimodal particle size distribution forms unusually long wavelength of 1-25 m where the wind is not strong enough to move the larger particles but strong enough to move the smaller grains by saltation.

Ripple marks are caused by water flowing over loose sediment which creates bed forms by moving sediment with the flow. Bed forms are linked to flow velocity and sediment size, whereas ripples are characteristic of shallow water deposition and can also be caused by wind blowing over the surface.
