Symmetric ripples are formed by bidirectional currents: currents that move in one direction and then in the opposite one. Does it ring a bell? Waves! Waves cause ripples to be symmetric because both sides of the ripple become alternatively sites of erosion and deposition while water moves back and forth.Oct 11, 2019

What are Ripple Marks? – Geology Page

Symmetrical ripple marks … Often found on beaches, they are created by a two way current, for example the waves on a beach (swash and backwash).

Ripple marks – Wikipedia

In geology, ripple marks are sedimentary structures (i.e., bedforms of the lower flow regime) and indicate agitation by water (current or waves) or wind.

Wave-formed ripple – Wikipedia

While wave-formed ripples are traditionally described as symmetrical, asymmetric wave ripples are common in shallow waters along sandy shores. They are produced …

Ripple Mark – an overview | ScienceDirect Topics

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 …

how symmetrical ripple marks form in sand – Earth Learning Idea

Because a two-way oscillating current is created, the ripple marks are symmetrical in shape. They only form at certain wave speeds – too slow, and the water …

ripple mark | geology | Britannica

ripple mark, one of a series of small marine, lake, or riverine topographic features, consisting of repeating wavelike forms with symmetrical slopes, …

Ripples and Dunes

Symmetrical ripples and dunes form where currents flow in two directions, as where waves wash back and forth. Preserved ripples and dunes thus provide clues …

Bedforms: ripples and dunes – Geology is the Way

Asymmetric ripples form at the contact between water/air and the sediment drag by a unidirectional current. The initial stages of formation of ripples are not …
