Assignments For This Topic...

This document is subject to revision, so reload this page in your browser every time you visit so that you will be certain to view the most current content.

The reading assignments are in the required textbooks listed on the main course syllabus (https://croninprojects.org/Vince/Course/PhysGeol/Geo1405-Spring2021.html. A reminder about how to get to the eText is provided HERE

1. Read : the study questions for this section, listed at https://croninprojects.org/Vince/Course/PhysGeol/Geo1405-SedRox-Q.html and keep them in mind as you read the following assignments. Most, if not all, of the answers will be in the reading assignments for this topic.
2. View a short video from Dave McConnell and friends — Sedimentary Rocks
3. Scan: Earth, chapter 7, Sedimentary Rocks
   Note that Tarbuck, Lutgens, and Linneman refer to "chemical" rocks in section 7.3, but it would be better to think of these as precipitated sedimentary rocks.
4. Read: Earth, chapter 7, section 7.1 An Introduction to Sedimentary Rocks and all of its subsections
5. Read: Earth, chapter 7, section 7.2 Clastic Sedimentary Rocks and all of its subsections. This introductory material will help you with Lab Activities 6.4 and 6.5.
6. Read: Earth, chapter 7, section 7.3 Chemical Sedimentary Rocks and all of its subsections
   Note that Tarbuck, Lutgens, and Linneman refer to "chemical" rocks in section 7.3, but it would be better to think of these as precipitated sedimentary rocks as contrasted with clastic (siliciclastic, bioclastic, volcaniclastic) sedimentary rocks or organic solids. Many limestones are mostly or entirely bioclastic sedimentary rocks.
7. Read: Earth, chapter 7, section 7.4 Coal: An Organic Sedimentary Rock.
   Note that coal is not actually a "rock" by common definition, because coal is not primarily made of mineral grains. Hence, referring to coal as an organic solid is preferred to referring to it as a rock.
8. Read: Earth, chapter 7, section 7.5 Turning Sediment Into Sedimentary Rock and its subsections
9. Read: Earth, chapter 7, section 7.6 Classification of Sedimentary Rocks. This background reading will help you with Lab Activity 6.6.
10. Read: Earth, chapter 7, section 7.7 Sedimentary Rocks Represent Past Environments and all of its subsections. This background reading will help you with Lab Activities 6.7 and 6.8.
11. Complete the lab assignment as described below
    
    Important Notes
    • A video conference will begin at the starting time each week for the lab section in which you are a registered student. You can ask questions related to the lab assignments during the weekly video conference. Each weekly conference will be accessible via a Microsoft Teams channel associated with your lab section. You can learn how to access your Microsoft 365 subscription as a Baylor student via https://www.baylor.edu/its/index.php?id=871490.
    • The completed laboratory activities assigned below must be submitted via the Canvas learning management system (LMS) before 11:59 PM Central Time on the day after the day on which your laboratory section is scheduled to meet (e.g., due before Wednesday night at 11:59 PM for a lab scheduled on Tuesday). Instructions for submitting your lab work are provided HERE.
    • The end-of-lab quiz must be completed via the Canvas LMS before 11:59 PM Central Time two days after the day on which your laboratory section is scheduled to meet (e.g., due before Thursday night at 11:59 PM for a lab scheduled on Tuesday).
