Which of the following processes can form a mineral? Select all that apply. A. cooling of melted rock B. changing heat and pressure C. erosion of sediments

A region is home to a large amount of petroleum. Which best explains the past processes that occurred in the region, as indicated by the presence of petroleum? A. Past hydrothermal activity occurred in the region, causing the formation and deposition of petroleum. B. The region experienced past volcanic activity that trapped ash underground, leading to the formation of petroleum. C. Marine sediment was buried and compacted; over millions of years, petroleum was formed, trapped beneath Earth’s surface. D. Weathering in the mountains in the region formed sediments; the deposition and compaction of these sediments formed deposits of petroleum.
