Instructor: Kevin Newton Kevin has edited encyclopedias, taught middle and high school history, and has a master's degree in Islamic law. Don't worry, this lesson isn't about how to take a stone out to dinner. Instead, it is about how geologists and archaeologists use different techniques to figure out how old rocks and other artifacts are. Why Care About Dating Rocks? Relative vs.

Lesson Summary In this lesson, we looked at the ideas of relative and numerical dating for geologists. Old as Dirt Geologists and archaeologists spend much of their efforts working out the ages of items under their study. Learning Outcome After reviewing this lesson, you should be able to: Define the methods of numerical and relative dating, in addition to related terms, such as law of superposition, principle of cross-cutting relationships, and half-lives Describe how both methods are used to date objects.Numerical Dating

May 20, Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.

Lab 5 - Relative and Numerical Dating Answer using the blanks provided and please make your answers highlighted in yellow.
Introduction Geologists have formulated several principles and laws that can be used to determine the relative ages of rocks. In the process of relative dating, scientists do not determine the exact age of a fossil or rock but look at a sequence of rocks to try to decipher the times that an event occurred relative to the other events represented in that sequence.
Also, with the discovery of radioactivity in the late s, scientists were able to measure the numerical ageor the exact age of some rocks in years.
