The flow creates a steep side down current. In this image, the flow is from right to left. Ripples are known by several names: ripple marks, ripple cross-beds, or ripple cross laminations. The ridges or undulations in the bed are created as sediment grains ...Ripples and Dunes. When a wind or water current flows across loose sand, the sand is dragged along the bottom and frequently is piled up to form ripples and dunes.

Current ripple marks indicate water and wind moving in one direction an example location would be a river or a stream B. oscillation ripple marks indicate water moving back and forward, example locations would be: tidal flats with tides, and shorelines with lakes 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. The symmetry of water-current ripple marks indicate whether they were formed by gentle waves or faster water currents.
