CSET - Geologic Time 083114 flashcards. Fairly Simple Exercises. John and Barbara Thomas The authors have been working with elementary school students for several years.
All of these exercises started 30 years ago when John was asked to do geology with the National Wildlife Association Conservation Summits. In his spare time, he always worked with several groups in the youth program (as young a four years old) and showed them rocks. One outgrowth of this was the exercise on classification. John was invited into his daughters' fourth grade classrooms to talk about geology and instead of talking about it designed and brought in activities. Introduction to Physical Geology Syllabus. The problem: By the mid 19th century it was obvious that Earth was much older than 6000 years, but how old?
This problem attracted the attention of capable scholars but ultimately depended on serendipitous discoveries. Early attempts: Initially, three lines of evidence were pursued: Hutton attempted to estimate age based on the application of observed rates of sedimentation to the known thickness of the sedimentary rock column, achieving an approximation of 36 million years. Formation of an Unconformity. Www.cposcience.com/home/portals/2/media/post_sale_content/pes/pes_chap_18/studentrecordsheets/pes_inv_as_18b.pdf. Age, Rocks, and Index Fossils.mp4. RELATIVE AGE. If the Law of Original Horizontality is applicable, it may be inferred that where sedimentary layers are found that depart appreciably from the horizontal, their inclination is the result of deformation that took place after the layers were deposited.
At location A, three layers are present. They have not been deformed and remain as originally deposited. The layers are covered except for the area within the circle. Looking at the exposed layers and applying the Law of Superposition, an observer concludes correctly that the bottommost layer (dark brown) is oldest and the topmost layer (orange-tan) is youngest. Nature & Science» Geology Resources Division. Since each of Grand Canyon’s three sets of rocks is unique, different dating techniques were used to determine the age of rocks in each set.
Radiometric dating techniques revealed the absolute age of the igneous and metamorphic rocks of the Vishnu Basement Rocks, and also provided dates on volcanic ash beds and other datable units in the mostly sedimentary Grand Canyon Supergroup. Relative dating, index fossils, and geologic correlation were used to determine the geologic age of the Layered Paleozoic Rocks, and numeric ages were then inferred. A wide variety of numeric ages for Grand Canyon rocks, particularly for the sedimentary rocks which usually cannot be absolutely dated, exist in both the technical and popular literature. When someone’s objective is really just to learn how long ago these rocks formed, it is very confusing to sort through subdivisions of geologic periods, the scientific names of microscopic index fossils, and the nuances of radiometric dating techniques. DETERMINING AGE OF ROCKS AND FOSSILS.
THE AGE of fossils intrigues almost everyone.
Students not only want to know how old a fossil is, but they want to know how that age was determined.

Answer 3: There are many ideas about why the Earth has many different layers, and no one really knows for sure.
Most scientists believe that the existence of layers is because of the materials that make up rocks and minerals. Under different pressures and temperatures, rocks and minerals change "state", in other words, they can melt or crystallize to form different rocks. For example, do you know about the gemstone called Garnet? It's a shiny red rock that people polish and cut and use in rings and necklaces. Earth Science - Activities/Labs.
