A region was covered by a shallow sea millions of years ago, where huge numbers of tiny marine organisms lived, died, and were buried under sediment. Today this region has large deposits of oil and natural gas. Which best explains this?

The buried remains of marine organisms were transformed into fossil fuels by heat and pressure over millions of years. The shallow sea evaporated and left behind oil and natural gas as minerals. Volcanic activity beneath the sea produced the oil and natural gas directly. The ocean water itself slowly turned into oil and natural gas as it cooled.

The buried remains of marine organisms were transformed into fossil fuels by heat and pressure over millions of years.
