General InformationLast Updated  •  November 26, 2011   
PLEASE NOTE:
Cellular phones, iPods, Blackberries, Bluetooth devices, headphones, computers or, in general, ANY KIND of electronic device CAN NOT be used during the test. All electronic devices MUST BE TURNED OFF: if a cell phone rings or a device is turned on in the classroom during test time, you will not be allowed to finish your test and your result will be invalidated.

You can not use any dictionary, translator, pocket calculator, flash card, or any external source of information. There will be no need for a ruler during this test. No hoods, hats, or anything that hides your ears will be allowed.

You will ONLY need to bring:

  1. one Scantron, Form 882-E
  2. a number 2 pencil
  3. an eraser

This study guide must be interpreted (literally) as a guide to the study of the subject and not as a listing of possible questions.
It is YOUR personal responsability to cover the materials listed in this online study guide

  • on the lecture textbook
  • on the lab textbook
  • on "Cradle of Life"
  • on the web pages
  • on your notes.

I would strongly recommend that you peruse your notes for completeness of information: some information that has been detailed in class is only mentioned briefly on the textbooks, and you are responsible for covering that; know what the key terms and concepts are (see the list at the end of each chapter on both your textbook and your lab manual); exercise with the questions for review also found at the end of each chapter. Review the materials from your quizzes.
Read the summary at the end of each chapter, try to answer review questions, try to work with others if you find it useful.
Never hesitate to ask me questions in class or during a lab.

Study Guide: part 1 - readings from "Cradle of Life"Last Updated  •  November 26, 2011    

All questions from William Schopf's book, Cradle of Life, will be out of chapters 7, 8, 9, and 10.
There will be no questions from chapters 11 and 12.
Refer to the familiar assignments for a review.

  • Chapter 7 describes stromatolites
  • Chapter 8 deals with the hypobradytelism of cyanobacteria
  • Chapter 9 goes over the development of eukaryotes
  • Chapter 10 ends our discussion and highlights the solution to Darwin's dilemma, a quandary that accompanied us since chapter 1

  1. Know the Geologic Time Scale
  2. Know Stratigraphic Units
  3. Know Earth's Absolute Age
    There will be no questions on the three modes of radioactive decay (page 137) and on the specifics of U/Th, U/He, Rb/Sr, K/Ar and Ar/Ar dating (pages 138 and 139).
    Do study U/Pb and radiocarbon dating and, of course, the rest of the section (including the 86Sr/87Sr graph of Figure 6.12, page 142).
  4. Know Event Stratigraphy
Some concepts may have been discussed in class only. Refer to your notes. This is one of the most important chapters of the book. Expect detailed questions out of this, and be able to apply the concepts expressed in this section to chapters.


Chapter 7 - Evolution and the Fossil Record
This chapter provides you with the foundations for the understanding of Evolution.
You should study the whole chapter and the integrating materials that you can find on the class web page. Here is a detailed summary of the materials you need to know:

  4. Read, in order to better understand the ideas behind the chapter, the section "Genes, DNA and Chromosomes" (there will be no direct questions on this short paragraph)
  5. Read, in order to better understand this chapter, the section "Populations, Species and Speciations". Know what a speciation is.
  6. Read, in order to better understand this chapter, the section "Rates of Origination". Know what evolutionary radiations and adaptive breakthroughs are.

  8. Know Evolutionary Convergence
  9. Know Extinction
  10. Know Evolutionary Trends
  11. Know the online notes on evolution

Chapter 8 - The Theory of Plate Tectonics

  1. Know the History of Alfred Wegener's continental drift theory
  2. Know about the rise of Plate Tectonics
  3. Know about paleomagnetism
  4. Know about deformation, strike and dip (see also the online notes for this section, parts I, II, and III)
  5. Know faults and folds (folds are mentioned in Chapter 9 on the textbook but you should have in-depth notes on both faults and folds, including materials on their classification, on strike and dip, on the hanging wall and the foot wall, etc.).
  6. Know about faulting and volcanism (seismic and volcanic activity) along Plate Boundaries
  7. Know about Plate Movements, including measuring the movement, hot spots, thermal plumes, etc.

Chapter 9 - Continental Tectonics and Mountain Chains
Know the whole chapter; expect many questions to come out of this chapter too (it has also been discussed, as the previous one, at least three times between lecture and lab)

  1. Know about the Rifting of Continents
  2. Know about Mountain Building, including examples
  3. Know about Suturing of Small Landmasses to Continents (exotic terranes)
  4. Know about the Tectonics of Continental Interiors

Chapter 10 - Major Chemical Cycles
Know the whole chapter

  1. Know the Introduction, what the greenhouse effect is, what greenhouse gases are
  2. Know about Chemical Reservoirs
