Answer to Question 1

Answer: Many sedimentary rocks also contain biologic remains called fossils. Living organisms abound in the same environments where sediment accumulates, and their remains are buried with the sediment. Geologists interpret ancient environments with the help of biologic remains preserved as fossils. Organic matter buried with sediment and sedimentary rock changes at elevated temperature and pressure to form combustible organic compounds that yield large amounts of energy when burned. These organic materials are the fossil fuelscoal, oil, and natural gas.

Answer to Question 2
