How do scientists use relative and absolute dating and the geologic time scale to organize earth's 4.6-billion-year-old history?

The relative and absolute dating methods are two types of dating techniques that are efficient;y used by the geologists in order to determine the relative and absolute age of a rock or fossil body.

The relative dating method provides the relative age of a rock or a fossil, whereas the absolute dating method provides the absolute age of rocks and fossils.

The relative dating method suggests the sequential arrangement of events. This means that it helps in evaluating which events have taken place earlier and which events have taken place later.

By using both the dating technique, and acquiring all these data regarding the fossils and rocks of ancient age and their orderly arrangement, it helped in constructing the well organised geological time scale and determined that the earth was formed about 4.6 billion years ago and since then continuous events and earth processes are taking place on earth.
