Relative dating is method of assigning ages to geologic events in nature. This is based on certain principles and laws proposed by earlier geologists.
Relative dating differs from absolute dating in that absolute dating assigns real quantitative numbers to geologic events.
- From the analogy of the building provided, according to the principle of superposition of strata, the oldest layer is at the bottom of the sequence and the youngest on top.
- The lowest part of the section must of the section must have been constructed before the parts above it were constructed.
- Based on the principle of cross cutting "geologic features that cuts another are usually younger than the sequence they cut through ".
