Great question! Geologists can use sedimentary structures and other features to help distinguish depositional environment. For example, aeolian (i.e., wind-blown) sand grains are generally frosted and the angle and magnitude of cross-bedding in sand dunes is much larger than in nearshore systems. Sometimes there are fossils that can with an interpretation. Aeolian rocks also often preserve inverse graded beds (coarsening-upward) that represents air-supported grain flows down the face of a sand dune, which you don't find in nearshore rocks.
Another excellent video. Stupid youtube algorithm, do your job and spread these far and wide! What are you waiting for, stupid youtube algorithm? Are you...scared people might learn something instead of being distracted by banal garbage you normally recommend? Get with the program, you damnable algorithm, or you're cruisin' for a bruisin'.
Just discovered your channel hopefully you can do more national park geography
Thanks so much for sharing your videos. I really enjoy them. Best wishes ⭐️🌈
how do we differentiate that the cliff house formation was actually deposited as marine near shore strata and isn't an aeolian sea?
