Chapter 7: Metamorphism
Chapter 8: Deformation
Please enter your responses in the text boxes provided. All answers should be given in complete
sentences. Responses should be 1-3 sentences. Upload this completed document to CANVAS by
the posted deadline.
Grading: Each homework assignment is worth 25 pts. One question (chosen at random) from
each assignment will be graded for content. This question is worth 5 pts. The other 20 pts are
earned based on completeness: 100% (20 pts), 75% (15 pts), 50% (10 pts), 25% (5 pts), less
than 25% (0 pts). Solutions will be posted online after the submission deadline so you can
check your own answers. Scores for late assignments will automatically be reduced by 25% for
the Sirst 24 hours, 50% for the second 24 hours. No assignments accepted more than 48 hours
after submission deadline.
Chapter 7
1. Explain how are metamorphic facies related to temperatures and pressures?
Temperature and pressure both are exogenous factors, which try to create a
balance upon the earths surface, by tethering and weathering away. During
Metamorphism temperature and pressure play a very prominent role in the
weathering of the rock. In addition, the rock is composed of various kinds of
minerals, and thus each mineral reacts differently with temperature and pressure
2. In which plate tectonics setting would you expect to >ind regional
metamorphism? Why?
The most regional geological process takes place inside the continental crust since
they produce metamorphic rocks. Hence, one would likely >ind them at an ocean
ridge setting
3. What is the signi>icance of eclogites that are found at the Earth’s surface? In
other words, where did they come from, how did they get to the surface?
