Name two methods by which we can identify the age of fossils. |
| Answer» Two methods to determine the age of fossils:Relative dating:When dug into the Earth, the fossils closer to the surface are more recent as compared to the fossils found in deeper layers.Radiometric dating:The fossils can also be dated by detecting the ratios of different isotopes of the same element in the fossil material. This process is known as radiocarbon dating. When living organisms change into fossils, their rate of radioactive C14 decay decreases slowly. In this way, the age of fossils can be determined with the help of radioactive C14. | |
