4. Discussion

The topic of our discussion- Faulting and Folding. There are two groups. Each group discusses the following monitoring packet. The monitoring packet- consists of 4 parts. (R.P. – 8.3.1.4, 8.3.2.3, 8.3.1.1)

Part 1- checks vocabulary by means of reading comprehension

Part 2- detail reading; questions that ask for specific details (using diagrams)

Part 3- main idea: checks the student's comprehension of the topic

Part 4- interpretive questions; requires the students to understand, analyze and infer from the text.

  8. Fault consists of two___________.

  9. The hanging wall of a fault is located ___________ the fault surface.

  10. The footwall of a fault is located __________ the fault.

  1. Fold is a deformation of strata formed by forces, such as __________ and __________.

  2. Faulting precedes or follows ____________.

3. ____________ is the locus of maximum curvature of a fold.

4. Inflection occurs where _________ changes to ______________.
