Symmetrical ripples form when

WebOct 6, 2010 · Ripples are caused by the flow of fluid (liquid or gas) over sediment. Symmetrical ripples form when there is a back and forth motion, like on a beach. Non-symmetrical ripples form when there is a ... In sedimentology, wave-formed ripples or wave-formed ripple marks are a feature of sediments (sandstones, limestones, siltstones) and dunes. These ripple marks are often characterised (and thus distinguished from current ripples) by symmetric cross sections and long relatively straight crests, which may commonly bifurcate. Commonly, these crests can be truncated by subsequent …
