Relative Age of Rocks Relative Dating: Order rocks deposited tells you relative age of rocks (order from old to young) Geologic Cross-Section Maps: show the structure of rocks underground. In the process of relative dating, scientists do not determine the exact age of a fossil or rock but look at a sequence of rocks to try to decipher the times that an event occurred relative to the other events represented in that sequence. You can see thousands of fossils right here under your feet! Fossils of plants and animals show how they changed and evolved throughout Earth's history. 12 through three methods: ) relative dating of the geologic features: (2) absolute dating of the igneous and metamorphic rock layers; (3) the use of index fossils to determine the age of sedimentary layers.
