fossils
They started out as the remains of marine animals and plants.
Such remains are known as fossils if the sediment is changed over eons into a sedimentary rock.
Fossil fuels (coal, oil and natural gas).
They are fuels that are natural substances and are found in the earth from the remains from dead plants and animals
Fossils are the remains of plants and animals, and fossil fuels are decomposed plants and animals that form coal, oil, and natural gas.
Tiny remains of animals and plants in streams come from the mountains. When it rains, these remains are washed down the mountains toward the streams.
Natural gas was formed from the remains of tiny sea animals and plants that died 200-400 million years ago. When these tiny sea animals and plants died, they sank to the bottom of the ocean where they were buried by layers of sediment that hardened into rock. Over hundreds of millions of years these energy-rich carbon remains were buried deeper and deeper under layers of this sedimentary rock that became thousands of feet thick. The enormous pressure of the ocean and these layers of rock, the heat generated by that pressure and the heat of the Earth's core combined to transform this organic material into petroleum and natural gas.
