I just found a video on sedimentary rock formationa video on sedimentary rock formation, and to my surprise, it stated that this only could occur in water! I always thought that any layer of matter, if buried deep underneath more matter, could form a sediment and become new rock. Am I completely wrong, or was the video simply not covering all bases?
I did Google it and check Wikipedia, but with my limited knowledge of the field, the results were inconclusive.
