Question

Quizplus · Accepted Answer

Ripples, dunes, and cross bedding are all sedimentary structures that form in response to the movement of sediment by wind or water. By analyzing the orientation and characteristics of these structures, geologists can infer information about the direction and strength of the wind or water flow, and the type of environment (e.g. desert, river, ocean) that existed in the past. Therefore, all of the choices (wind direction, current direction, past environments) are correct.
