UNIT QUIZ: Unit 9 Review Quiz

Take this quiz only after you've gone over the materials for this unit (Depositional Environments and Sedimentary Rocks).

This quiz contain 35 questions about the topics/ideas/concepts discussed in this unit and will be used to measure your understanding of these topics/ideas/concepts. Questions will be taken from both the readings and video resources presented in this unit.

You can take this quiz multiple times, but you'll need to get 80% or higher before you can proceed to the next unit. If you do not reach 80% on your first attempt, use it to identify your knowledge gaps (concepts from the video that you are still struggling to understand). Once you identify these gaps, go back to the reading and video materials and review these concepts BEFORE starting your second attempt at the quiz. Only the highest grade among all your attempts will be uploaded to the gradebook.

The essential learning outcomes for this unit are:

• Distinguish between three major categories of sediments;
• Describe clastic sediment in terms of size, sorting, and roundness;
• Identify where and how chemical and biogenic sediments are formed;
• Summarize the main mechanisms of sediment transport;
• Define deposition and describe the conditions that commonly lead to the deposition of sediment;
• Describe the environments where deposition takes place on land and near the ocean;
• Relate the appearance of sedimentary rock to its mode of formation;
• Summarize the processes that lead to the lithification of sediment;
• Identify the most common clastic, chemical, and biogenic sedimentary rock types;
• Explain how features such as ripple marks, mudcracks, and fossils can tell geologists about their depositional environment;
• Describe the concept of sedimentary facies;
• Identify tectonic environments that are favorable for the accumulation of sediment;
• Explain how divergent plate margins influence sedimentation;
• Describe what happens to sediments during continental collisions and in subduction zones at convergent plate margins.

Directions:

1. You are allowed multiple attempts at this quiz.
2. The highest grade of all your attempts will be listed as your grade for this quiz on the gradebook.
3. This quiz will be available to you for a minimum of 7 days and you can take it at any time during this availability window.
4. However, once you start the quiz you will have only 70 minutes to complete it.
5. The deadline to attempt this quiz will be on Wednesday, October 25, 2017, at 2:59 pm.
6. Late submissions will still be accepted, but you will miss 1 point for every hour beyond the deadline. These points will be deducted from whatever grade you have, for this quiz, on the gradebook.
