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?
Organic material (dead plants and animals) was buried under sediments and compacted; over millions of years, petroleum was formed, trapped beneath Earth's surface.
Past hydrothermal activity occurred in the region, which is near subduction zones, causing the formation and deposition of petroleum.
Weathering in the mountains in the region formed sediments; the deposition and compaction of these sediments formed deposits of petroleum.
The region experienced past volcanic activity that trapped ash underground, leading to the formation of petroleum.
