Sure! Here's a clear and concise answer to your question:
1. In my state of California, one common resource is petroleum, also known as oil.
2. Evidence for the past geologic processes leading to the formation of petroleum includes the accumulation of organic matter from marine plants and animals over millions of years. This organic material was buried deep underground where high pressure and temperature transformed it into petroleum.
3. Present geologic processes that sustain petroleum formation involve the slow movement of tectonic plates, which create subsurface traps where oil can accumulate. Additionally, the ongoing deposition of sedimentary layers provides the necessary conditions for the preservation and further formation of petroleum reserves.
By understanding these geologic processes, we can appreciate how the natural history of our state has contributed to the availability of resources like petroleum.
