Preparation Questions

Before each class lecture I will post here a list of preparation questions. These questions are designed to prepare you for each lecture. If we have a pop quiz on the listed day, it will include these questions AND at least one surprise question from previous lectures to encourage  review. I recommend you thus have answers for them — at least in your head! — before each class meeting. You will have twelve pop quizzes by the end of the course, with the lowest two grades dropped. If you are absent for any reason when a quiz is given (other than a scheduled college event you told me about in advance), your grade will be recorded as a zero. You may use any source to answer these questions before class. For a quiz, of course, you’re on your own.

January 28 (Tuesday) —

1. What is a flow regime in sedimentology? This includes upper and lower flow regimes. Use the terminology you learned in the last class. This will require a bit of digging.

 

January 23 (Thursday) —

1. What is Bernoulli’s Principle? Where in our class material yesterday have you seen it in action, although not named?

2. What do we mean when we say a grain saltates in a moving fluid?

 

January 21 (Tuesday) —

1. Why is the mineral olivine so rare in sediments formed on the North American continent? Where must you go to find it as a common component of the sediment?

3. Please review (or meet for the first time) Bowen’s Reaction Series. What role does it play in the mineralogy of sediments?

 

January 16 (Thursday) —

1. What is the difference between permeability and porosity?

2. Why is quartz the most common siliciclastic mineral in sedimentary rocks?  (And what does siliciclastic mean, anyway?)

3. Feldspar minerals undergo hydrolysis during weathering on the Earth’s surface.  What is hydrolysis and what are the results from the hydrolysis of feldspar minerals?  We will come back to this process several times in this course.

4. Always be ready for a review question!
