SCIN 138 Week 5 Exam Questions and Answers | American Military University, 2021

At what temperature does diagenesis end and metamorphism begin? • A. 1,000 bars • B. 3,000 kbars • C. 100 degrees Celsius • D. 200 degrees Celsius Feedback:Metamorphism starts at around 200 degrees Celsius. Below that temperature is considered diagenesis, which includes sediments solidifying (compacting and cementing) into sedimentary rocks. Question 2 of 25 4.0 / 4.0 Points Which metamorphic facies is associated with subduction zones? • A. greenschist • B. lawsonite-blueschist • C. granulite • D. epidote-eclogite Feedback:by analyzing the Chapter 6 diagram, lawsonite-blueschist is shown on the left at a low temperature but at a high pressure. The associated diagram indicates that high pressure and low temperature minerals are found at subduction zones. Question 3 of 25 0.0 / 4.0 Points Which type of metamorphism is responsible for the greatest amount of deformation? •
