Relative Age-dating — Discovery of Important Stratigraphic Principles
Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.
At 17, Dick Myers knew he was too small to play basketball at a major college. So, the Kansas native enrolled at nearby Hutchinson Junior College to gain height, weight and skill — hoping to eventually catch the eye of recruiters and coaches. The year was and two years later, Don Haskins came calling. Suman Sirimulla, Ph. Since Amanda Labrado was a young girl, she has been passionate about rocks and the great outdoors. Franchesca E.
The Principle of Superposition tells us that deeper layers of rock are older than shallower layers Relative dating utilizes six fundamental principles to determine the relative age of a formation or event. This follows due to the fact that sedimentary rock is produced from the gradual accumulation of sediment on the surface. Therefore newer sediment is continually deposited on top of previously deposited or older sediment.
In other words, as sediment fills a depositional basins we would expect the upper most surface of the sediment to be parallel to the horizon.

In this two-hour special, renowned paleontologist Kirk Johnson takes us on an epic adventure through time at the polar extremes of our planet. Following a trail of strange fossils found in all the wrong places—beech trees in Antarctica, hippo-like mammals in the Arctic—Johnson uncovers the bizarre history of the poles, from miles-high ice sheets to warm polar forests teeming with life. What caused such dramatic changes at the ends of the Earth? Premiered February 5, Yet hidden in these rocks, buried under the oceans and trapped in the ice, are clues that reveal a totally different past….
What powerful forces drove the poles to such extremes? This place is a dream. Think of all the other places you could be right now, then think about where you actually are. These icebergs are amazing. And they come in all sizes, from the size of little tiny ice cubes, all the way up to the size of mountains.

Teaching about Earth’s history is a challenge for all teachers. Time factors of millions and billions of years is difficult even for adults to comprehend. However, “relative” dating or time can be an easy concept for students to learn. Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on “rock layer” cards.

The five categories included in the peer review process are. This activity has benefited from input from faculty educators beyond the author through a review and suggestion process. This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others’ activities and offered feedback and ideas for improvements.
Students don’t have to be passively taught the important principles geologists use to do relative age-dating of rocks and geologic events. By careful analysis and critical thinking about photos and illustrations of rock outcrops, they can discover these principles themselves, and present their discoveries to the class! When piecing together the geologic history of the Earth, geologists rely on several key relative age-dating principles that allow us to determine the relative ages of rocks and the timing of significant geologic events.
But why not start with the examples and let students discover these principles for themselves? Students are split into small groups which each work to discover a different relative age-dating principle. The groups are shown photos and given handouts with drawings of rock outcrops illustrating the various principles. These handouts include worksheets for which they must answer a series of prompts that help lead them to the discovery of their relative age-dating principle.
