What are fossils ? How do we know how old the fossils are ? |

Answer» Your friend is absolutely right- There are two ways by which we can determine the age of fossils- (1) If we dig into the earth and start finding fossils, it is reasonable to suppose that the fossils we nd closer to the surface are more recent than the fossils wend in deeper layers. (2) By detecting the ratios of different isotopes of the same element in the fossil material. This method is known as carbon dating |
