1.) For our Week 7 Written Assignment, we will be using the made-up scenario provided above for working with the best applications of numerical dating techniques for a log buried in a Holocene flood and a Permian felsic volcanic unit. These examples will allow us to practice using the geologic time scale from our textbook on page 293 (Figure 9.24) and work with the dating techniques. Make sure to notice that the time scale on the right of the figure is a section being blown up of the time scale on the left side of the figure. Also be sure to look at the title of each column Eon, Epoch, Period, etc. this will be relevant when answering the questions. All the information you will need for this assignment is in our textbook and lecture material, therefore there is no need for any additional sources.
The attachment have the page 293
2.) **Remember to always label the time scale that you are using when answering these questions below. A time scale label example is thousands of years ago, days old, minutes old, billions of years ago, etc.***
3.) Geologic Time Scale Practice:
a.What is the age label for the geologic time scale we are using (refer to the far right column)? This is what MYA stands for.
b. The numerical age range of the Mesozoic Era is 251 million years ago to 65.5 million years ago per the geological time scale on page 293 of our textbook. What is the numerical age range of the Cambrian Period?
c.What is the name of the Eon with the numerical age range of 2,500 542 million years ago? REMEMBER: the answer is in the EON column each column is a different type of age category.
d. What is the name of the Era that covers the time age range from 65.5 million years ago to the present?
e. What is the oldest numerical age listed on this time scale? Give the number.
4.) Our made-up example states that there is a log buried in a Holocene flood, which came first the log or the flood? Essentailly, think of which item had to be present first in order for the other item to bury the first item.
5.) What is the numerical age range of the Holocene Epoch?
6.) What is the main element that the tree is made of? This is one element from the Chemical Periodic Table, An example of an element is H (for hydrogen) or Sn (for tin) now which element is the main one in trees? Check out the periodic table here http://periodic.lanl.gov/index.shtml
7.) Now that you know what numerical age range the log is from, and what material the log is made of take these two pieces of information to decide on one type of numerical dating technique that would work to date the log. REMEMBER: Be specific dont just say radiometric dating because there are many types of radiometric dating methods pick one covered in the book.
8.) Give two reasons why you chose the numerical dating technique that you did in question 7 for the log.
9.) What is the numerical age range of the Permian Period?
10.) What type of rock is a Felsic Volcanic Unit it is one of the three rock types from the rock cycle we reviewed in week 3? We know that a felsic volcanic rock is more than 65% Silica and includes large amounts of Aluminum, Potassium and Sodium, thus meaning it is highly viscous. REMINDER: the answer is one of the three rock types in the rock cycle
11.) Now that you know what numerical age range of the Permian Period and what type of rock the Felsic Volcanic Unit is, take these two pieces of information to decide on one type of numerical dating technique that would work for this rock in this scenario. NOTE: Be specific just dont day radiometric dating it is all radiometric dating the book covers specific methods pick one of those.
12.) Give two reasons why you chose the numerical dating technique that you did in question 11 for the rock.

| Content (worth a maximum of 50% of the total points) |
Zero points: Student failed to submit the final paper. |
20 points out of 50: The essay illustrates poor understanding of the relevant material by failing to address or incorrectly addressing the relevant content; failing to identify or inaccurately explaining/defining key concepts/ideas; ignoring or incorrectly explaining key points/claims and the reasoning behind them; and/or incorrectly or inappropriately using terminology; and elements of the response are lacking. |
30 points out of 50: The essay illustrates a rudimentary understanding of the relevant material by mentioning but not full explaining the relevant content; identifying some of the key concepts/ideas though failing to fully or accurately explain many of them; using terminology, though sometimes inaccurately or inappropriately; and/or incorporating some key claims/points but failing to explain the reasoning behind them or doing so inaccurately. Elements of the required response may also be lacking. |
40 points out of 50: The essay illustrates solid understanding of the relevant material by correctly addressing most of the relevant content; identifying and explaining most of the key concepts/ideas; using correct terminology; explaining the reasoning behind most of the key points/claims; and/or where necessary or useful, substantiating some points with accurate examples. The answer is complete. |
50 points: The essay illustrates exemplary understanding of the relevant material by thoroughly and correctly addressing the relevant content; identifying and explaining all of the key concepts/ideas; using correct terminology explaining the reasoning behind key points/claims and substantiating, as necessary/useful, points with several accurate and illuminating examples. No aspects of the required answer are missing. |
| Use of Sources (worth a maximum of 20% of the total points). |
Zero points: Student failed to include citations and/or references. Or the student failed to submit a final paper. |
5 out 20 points: Sources are seldom cited to support statements and/or format of citations are not recognizable as APA 6th Edition format. There are major errors in the formation of the references and citations. And/or there is a major reliance on highly questionable. The Student fails to provide an adequate synthesis of research collected for the paper. |
10 out 20 points: References to scholarly sources are occasionally given; many statements seem unsubstantiated. Frequent errors in APA 6th Edition format, leaving the reader confused about the source of the information. There are significant errors of the formation in the references and citations. And/or there is a significant use of highly questionable sources. |
15 out 20 points: Credible Scholarly sources are used effectively support claims and are, for the most part, clear and fairly represented. APA 6th Edition is used with only a few minor errors. There are minor errors in reference and/or citations. And/or there is some use of questionable sources. |
20 points: Credible scholarly sources are used to give compelling evidence to support claims and are clearly and fairly represented. APA 6th Edition format is used accurately and consistently. The student uses above the maximum required references in the development of the assignment. |
| Grammar (worth maximum of 20% of total points) |
Zero points: Student failed to submit the final paper. |
5 points out of 20: The paper does not communicate ideas/points clearly due to inappropriate use of terminology and vague language; thoughts and sentences are disjointed or incomprehensible; organization lacking; and/or numerous grammatical, spelling/punctuation errors |
10 points out 20: The paper is often unclear and difficult to follow due to some inappropriate terminology and/or vague language; ideas may be fragmented, wandering and/or repetitive; poor organization; and/or some grammatical, spelling, punctuation errors |
15 points out of 20: The paper is mostly clear as a result of appropriate use of terminology and minimal vagueness; no tangents and no repetition; fairly good organization; almost perfect grammar, spelling, punctuation, and word usage. |

5 points out of 10: Appearance of final paper demonstrates the student’s limited ability to format the paper. There are significant errors in formatting and/or the total omission of major components of an APA 6th edition paper. They can include the omission of the cover page, abstract, and page numbers. Additionally the page has major formatting issues with spacing or paragraph formation. Font size might not conform to size requirements. The student also significantly writes too large or too short of and paper |
