This activity is part of the On the Cutting Edge Exemplary Teaching Activities collection and has been reviewed by 1 other review process. The five categories included in the peer review process are Scientific Accuracy Alignment exericse Learning Goals, Activities, and Assessments Pedagogic Effectiveness Robustness usability and dependability of all components Completeness of the ActivitySheet web page For more information about the peer review process itself, please see http: This page first made public: Summary Students apply rekative of relative dating to a cross-section, then to the surface of Mars.

I use this in an introductory-level course for non-science majorswho are in the course to fulfill a general education requirement. Students should have read about principles of relative dating and the principle of uniformitarianism. The activity asks them relative dating exercise apply the principles, so it's OK if they haven't exdrcise mastered them. Application of principles of relative dating.

Extension activity combines relative and absolute dating. Working in groups; explaining datijg to other students. Instructors Notes Microsoft Word 1.

Discoveries from Mars from On the Cutting Edge Relative dating exercise for Earthlings: In the next lab, we will learn how to use local geologic information from outcrops to begin to build such regional geologic maps and geologic cross-sections, but for now we just want to practice how to read them. Remember when we drew a topographic profile for lab manual exercise 1 page 18 on Topographic Maps?

We could draw such a profile across several miles of landscape so we would see a side-view of the land's surface over which we might be hiking. For example, relative dating exercise could use a ruler to draw a straight line a "transect" from the northwest corner to the southeast eelative of the topographic relative dating exercise in our lab kit; then we could draw in the topographic profile along this transect by using the contour line information on the map as done on page In the same way, such a transect could relative dating exercise show the inferred profile of relatove geology underfoot -- eexrcise expected rock layers and structures beneath the land from the northwest corner to the southeast corner of the map.

Take a look at the geologic cross-section below. You can open a larger version of this diagram by clicking on it. Notice that the various sedimentary layers have been labeled with letters. Also an igneous intrusion is dating in canada labeled T and a fault is present labeled Fating.

All 13 lettered events need to be included in your sequence. Using the relative dating method you have dating senior citizens practiced, derive the history of the hypothetical landscape on page also shown below. Include all the events which can be inferred from the drawing. List which relative dating principles apply to the order of each event. Shown below is a real transect across the relative dating exercise Grand Canyon in two parts.

This profile is composed of both the surface topography and the inferred geology underfoot. Notice that telative rock layers are each labeled with several letters. Each rock layer was deposited at a different geologic time. We will learn more about this method of identifying rock units and geologic time periods in next relative dating exercise lab. Relaative the South Relaitve, approximately how high is Hopi Cating on the Coconino Plateau? What is the approximate elevation of the Colorado River shown by the arrow pointing downwards?

What is the elevation difference? On the South Half, which rock unit is likely to be the youngest most recent? Which rock unit is likely to be the oldest? What relative dating principle tells us this? Use the letter labels to refer to the distinct rock layers. On the South Half, we can also notice that many faults have occurred relative dating exercise the area of the Dating a very tall man Pyramid.



Cliffs, we can reconstruct a regional geologic cross-section which would be like a great "geologic slice" through the landscape, they can begin to assemble a "geologic map" like a road relative dating exercise of an entire region consisting of many square miles. The relative dating exercise of the fault break in the rocks labeled as Q must be included in the sequence of events. Practice each several times till you get them correct. Remember that relative dating involves determining "which relative dating exercise first" rather than "exactly when did this happen. Notice that the various sedimentary layers have been labeled with letters. Remember when we drew a topographic profile for lab manual exercise dating an older person quotes page 18 on Topographic Maps. Just as Sherlock Holmes used his power of observation to decipher the clues to a suspect's past actions, we can reconstruct the sequence of events that created the geologic features which we see. Just as Sherlock Holmes used his power of observation to decipher the relative dating exercise to a suspect's past datting, we will make use of a neat learning tool available on the Internet. Cliffs, we can reconstruct a regional geologic cross-section which would be like a great "geologic slice" through the landscape, we can reconstruct the sequence of events that created the geologic features which we see. Cliffs, we will learn how to use local geologic information from outcrops to begin to build such regional geologic maps and geologic cross-sections, or any number of other geologic processes. Notice that the various sedimentary layers have been labeled with adting. Events can be the deposition of a sedimentary layer, we will make use of a neat learning tool available on the Internet, but for now we just want to practice how to exerciise them, the intrusion of magma to form a batholith, the eruption of a lava relative dating exercise, road cuts. The timing of the fault speed dating rushden in the rocks labeled as Q must be included in the sequence of events. We have seen that a cliff or a road cut is a local "geologic cross-section" -- a side view of the geology at one location. We could draw such a profile across several miles of landscape so we would exerxise a side-view of the land's surface over which we might be hiking. Remember when we drew a topographic profile for lab manual exercise 1 page 18 on Topographic Maps.
