Quizplus · Accepted Answer

Large cross beds are characteristic of sediment that has been deposited by moving water or wind, indicating that the sediment was transported by a current or wind and then deposited. Therefore, option C, by the wind or a water current, is the most accurate answer. Options A and B are unlikely since deep ocean sediment tends to have more fine-grained particles, and lake sediment would likely have different sedimentary structures. Option D is also unlikely as debris flows typically produce different sedimentary structures. Option E is too broad and not specific enough.
