A ripple mark is a regular wave-like trace that forms on the surface of sediments or sedimentary rock. It is a typical sedimentary structure and an important marker to assess the sedimentary environment. Ripple marks usually form on the top of a rock layer and can also appear on the bottom of the overlying strata.Overview. A depositional environment is the accumulation of chemical, biological, and physical properties and processes associated with the deposition of sediments that lead to a distinctive suite of sedimentary rocks. Sedimentary environments are interpreted by geologists based on clues within such as rock types, sedimentary structures, trace ...

Ripple marks, both wave-formed and current-formed, are of value in determining the environments under which sediments are deposited and also the sequence of their deposition. Both kinds of ripples form on stream bottoms as well as on the bottoms of lakes and other bodies of water. A number of important differences are given that help to ...

What is process of formation of ripple marks? Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment. Ripples may be made by water or, in sand dunes, by wind. The symmetry of water-current ripple marks indicate whether they were formed by gentle waves or faster water currents.1 day ago · Study with Quizlet and memorize flashcards containing terms like Which of the following statements is true?
