Ripple marks are small ridges, generally less than one inch high and 2 to 8 inches wide. The ridges are developed by moving water and form perpendicular to the direction of water movement. If the profiles of the ripple marks are symmetrical, they are caused by waves; if the profiles are asymmetrical, they are caused by currents.ripple marks; mudcracks; graded beds; loading structures; sole structures; burrows; stromatolites; In igneous rocks, there are fewer options, but a few that are handy include: vesicle concentration; apophyses; pillow structures; in a few rare intrusions, primary structures including grading and cross-bedding(!)Earth Science Chapter 6: Rocks.

sedimentaiy rocks. The following is a brief discussion of some of these. 1. Ripple marks are produced on the top surfaces of beds by either wind or water movement. Asymmetrical ripple marks indicate a current flowing in only one direction (e.g., in a river), whereas symmetrical ripple marks are generally produced under the influence of Deserts can be environments of deposition, transport and erosion. Winddeposited sediments can include ripples, dunes and cross-beds. Desert winds can transport small grains across long distances and even create dust storms. Wind can also. erode pre-existing rock by abrasion and sandblasting.
