Fossils dating rock
To help you learn and understand key science terms and concepts, we’ve identified some of the most important ones and provided detailed definitions for them, written and compiled by Chegg experts.
It is based on the fossils found in rocks of different ages and on radiometric dating of the rocks.
Once the rocks are placed in order from oldest to youngest, we also know the relative ages of the fossils that we collect from them.
Relative age dating tells us which fossils are older and which fossils are younger. To get an age in years, we use radiometric dating of the rocks.
is, as mentioned earlier, the technique of piecing together the informational content of separated outcrops.
When information derived from two outcrops is integrated, the time interval they represent is probably greater than that of each alone.
In science there are many key concepts and terms that are crucial for students to know and understand.
