Relative dating cannot establish absolute age, but it can establish whether one rock is older or younger than another.Relative dating requires an extensive knowledge of stratigraphic succession, a fancy term for the way rock strata are built up and changed by geologic processes.| Teaching Weathering, Erosion, & Deposition | | Teaching the Metric System | Teaching the Water Cycle | Teaching Plate Tectonics | Teaching Earthquakes | Teaching Volcanoes | | Teaching Experimental Design | Contains over 200 pages of ready-to-run materials covering: Relative and Absolute Time, Sequencing Geologic Events, Geologic History Timelines, Geologic Eras, Fossils, Tree Cookies, and Radiactive Dating.Since we assume all the layers were originally horizontal, then anything that made them not horizontal had to have happened after the fact.
The Packet contains: Objectives and strategies, detailed lesson plans & ideas, bellwork and journal suggestions, labs and worksheets with answers, tests & quizzes with answers, active learning suggestions including the Rules of the Game Foldable, and game suggestions you can run off on colored paper.
In this lesson, we'll learn a few basic principles of stratigraphic succession and see whether we can find relative dates for those strange strata we found in the Grand Canyon.
Personally, I take that as a "yes" we did date back in the day.
If it is true they dated, I think it was around the time the ' Jumpin Jumpin' video or either their first video ' No No No'.
Long before geologists tried to quantify the age of the Earth they developed techniques to determine which geologic events preceded another, what are termed "relative age” relationships.
