In these rock layers, the sedimentary rocks are also known as strata. The rocks are formed by the three main procedures of sediment supply, comminution as well as coalescence, and the further discussion can be defined as follows:
- Geologists can have a clear idea of the time scale by analyzing these rocks.
- The geologists could indeed easily create the time scale by examining their structure, trying to date, visual appeal, etc.
- The absolute divisions in time scales were determined by the radioactive dating, which helps to mass extinction but there's much to be studied.
- Mass extinctions helped produce fossils and other historic artifacts that can help scientists start coming up with how they might have done look like while they were approximate.
Therefore "By studying rock layers as well as fossils all around the world, scientists have developed the time frame".
