In its place, the particles that settle from the transporting medium will be finer-grained, and there will be a lateral transition from coarser- to finer-grained material. Geological history of Earth Timeline of geology. The absolute dating is also sometimes referred to as the relative numerical dating as it comes with the exact age of the object.
Many of the same principles are applied. Sediment will continue to be transported to an area and it will eventually be deposited. With death, the uptake of carbon stops. Absolute dating provides a numerical age for the material tested, while relative dating can only provide a sequence of age.
