Sedimentation is the reason of Ripple marks.
Water flowing over loose sediment creates bed formations by displacing the sediment with the flow, which is what causes ripple imprints. In contrast to ripples, which are typical of shallow water deposition and can also be brought about by wind blowing over the surface, bed formations are related to flow velocity and sediment size.
<h3>How do ripple marks work?</h3>
Sand ripples, represented by the marks observed on beach sand or the bottom of a shallow stream, are created by forces like wave-related forces or wind-related forces, which are characteristic of the deposition of inorganic materials in shallow water.
<h3>What is Sedimentation ?</h3>
The process of allowing particles suspended in water to separate under the influence of gravity is known as sedimentation. Sludge is the term for the sedimentary particles that form from the suspension during the water treatment process.
so, Ripple marks are the result of sedimentation during deposition.
