Compare and contrast relative age dating with radiometric age dating. What is a limitation (if any) of each?
What will be an ideal response?
Relative age dating is when the ages of rocks are determined by their placement and proper sequence of formation and radiometric age dating is when the ages of rocks and minerals are determined using radioactive isotopes. Radiometric dating is more reliable because the rates of decay for many isotopes have been precisely measured and do not vary under the physical conditions that exist in Earth's outer layers. Relative age dating cannot tell us how long ago something took place, only that is followed one event and preceded another. The limitation of radiometric dating is it is only accurate when the mineral is in closed system.
