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.
