What could a geologist say about that section of rock?

Because the sedimentary rock had to have formed around the object for it to be encased within the layers, geologists can establish relative dates between the inclusions and the surrounding rock.

We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!

Geologists establish the age of rocks in two ways: numerical dating and relative dating.

Numerical dating determines the actual ages of rocks through the study of radioactive decay.
