RELATIVE DATING LAB Name: - tuh Mf D Date: V/“/ 2.9 Objective To identify the sequence of events when viewing a rock outcrop Materials + Cross-sections of the rock outcrops for each part (you can print them if it helps you) » Worksheet opened to record the data as you work through each cross-section Procedure + Read through all the steps below and then complete the Purpose question in the worksheet. « Determine the sequence of events for each of the cross-sections and list them in order from oldest to the most recent (youngest) and put the letters in that order on the worksheet. .

Application (10 pts) Locate the image near the top of the article entitled More and More Wrong Dates. You do not have to read the article, but notice where the author has drawn attention to the Cardenas Basalt layer and the basaltic lava flows of the Uinkerat Plateau with red arrows. This image depicts a cross section of the Grand Canyon. Many conventional scientists rely on radiometric dating as evidence that the rocks on Earth are millions of years old. Some Young-Earth Creation scientists did a test on the radiometric dates for the Cardenas Basalts positioned way down deep in the Grand Canyon and the basaltic lava flows on top. The creationists were convinced that the tests conventional scientists use ate flawed. As it turned out, one of the tests incorrectly determined that the basaltic lava flows on top were older in age than the Cardenas basalts on the bottom! If these dates wete accurate, which relative dating law would be broken in this situation? 1 he low oFf 5. per pos e,
