Ripple marks caused by water may appear on rock, or on sand cau

Descriptions of ripple marks, in both modern and ancient sediments, far exceed those of cross-bedding and are truly voluminous. Beginning in the later part of the 19th century, much effort has been devoted to qualitative appraisal of the environmental significance of both cross-bedding and ripple marks. In contrast,Ripple marks are formed due to the presence of waves of wind or water flowing above the surface of sand. In an area of dry sand, wind picks up the small particles up in the air. Due to gravity, these small particles will fall back to the desert floor. This continuous process of lifting and falling of sand particles eventually form the ripple ...When it comes to summer fashion, a pair of comfortable and stylish shorts is a must-have in every man’s wardrobe.

Despite decades of observations of current ripples, there is no universal scaling relation to predict their size or to distinguish them from dunes.Ripple Marks: Either symmetrical or asymmetrical ripples present on bedding surfaces. Water or air currents. Asymmetrical ripples indicate unidirectional currents with the steep slope facing down current and the shallow slope facing up the current. Symmetrical ripples indicate bidirectional currents.Ripple marks can be found as undulations on the non- cohesive surface, though they can also be found infrequently in muddy sediments too.
