Study Notes
Fossil Formation
- Fossils form when something dies and is covered by sediment.
- Sediment turns to rock, transforming the organism into a fossil.
- Layers of rock may flatten the fossil.
- Fossils can be seen on the surface of rocks after erosion.
Radioactive Carbon Dating
- Radioactive carbon (RCD) is naturally present in the air and living organisms.
- Living things constantly incorporate RCD into their tissues.
- After death, the intake of RCD stops.
- RCD slowly breaks down to its non-radioactive form.
- By calculating the remaining RCD, scientists can determine the time of death (absolute dating).
- This method helps determine the age of fossils.
Fossil Age Calculation
- Fossils' ages can also be determined by counting rock layers.
- Fossils are preserved parts or traces of organisms, often found in rocks.
- Organisms are buried quickly after death to prevent decay.
- Minerals gradually replace the organism's remains over time.
