Explain Relative Dating vs. Absolute Dating
What is....
• Relative dating is determining the relative order of
events without dates (this is done using geologic principles that rely on common sense reasoning and logic.)
• Absolute time is when you put a date or time for
an event (this is done using radiometric dating which relies on the fact that radioisotopes decay at constant rates.)
