Exercise Ten / Geologic Time 177 d. Based on the ages of the rock layers in outcrop 1, identify an unconformity. Remember that an unconformity is a break in the rock record. Draw a wavy line on the figure to represent the unconformity.

Radioactivity has provided a reliable means for calculating the numerical (absolute) age of rocks, a procedure called radiometric dating. Radioactive isotopes, such as uranium-238, emit particles from their nuclei that we call radiation. Ultimately, the process of decay…
