Read pages 200-215 in the Online textbook. Ignore the section on “What did they look like” and Non-Radiometric Absolute Dating Methods (end of pg 215). Answer All of the following questions.
The book and PowerPoint review a variety of Relative and Absolute dating techniques applied to the fossil record.
What is the difference between Relative and Absolute dating?
Explain the law of superposition and stratigraphic correlation, and discuss how they relate to relative dating?
What is Fluorine dating and how can it be used to correlate animal remains?
Biostratigraphy is a primary dating technique used in paleontology. It relies heavily on the law of superposition, stratigraphic correlation, and the use of Index Fossils.
What are Index Fossils? (use book and powerpoint)
Considering the three principles listed above, what is biostratigraphy and how does it work?
Understanding Radiometric Dating is of great importance to this course. Please consider the book section and the powerpoint carefully
Define and explain the term Isotope (include the structure of an atom)
What makes an isotope Radioactive?
What is Radioactive Decay?
What is a half-life?
The three radiometric (absolute) dating techniques that we will need to know for this class include Carbon 14, Potassium-Argon, and Uranium Series. For this question you will need to explain each one. Include how the method works, the age range it can be applied too, the material that the date is obtained from, and what circumstances it is best used in.
