Hint : refer to your pre-lab reading for the geothermal gradient formula. Assume that the lines start at the surface at a temperature of 0 o C. Use the isotherms you drew to estimate the temperature at the bottom end of the line. Include units ( o C/km) Line A: __________________ Line B: __________________ c. Increasing pressure causes rocks to become more dense as they get metamorphosed. Look at where eclogite forms. Do you expect eclogite to be very dense? _________________________________________________ What effect do you think this has on plate tectonics (think about why the plates move)? _________________ ________________________________________________________________________________________ Activity 4: A Comprehensive Review Now that you have seen all three main types of rocks (igneous, sedimentary, metamorphic), think about the characteristics of each group. 1. How can you tell a rock from a mineral? _______________________________________________________ __________________________________________________________________________________________ 2. How can you tell a non-foliated metamorphic rock from a plutonic igneous rock? _____________________ __________________________________________________________________________________________ 3. How can you tell a breccia or a conglomerate from a porphyritic rock?________________________________ __________________________________________________________________________________________ 4. How can you tell a biochemical sedimentary rock from a fine-grained clastic sedimentary rock (e.g. limestone vs. mudstone)? _____________________________________________________________________________ __________________________________________________________________________________________

Lab #5: WWU Campus Geology Tour 79 Lab #5: WWU Campus Geology Tour Geology encompasses more than landscapes. The materials used to build cars, bikes, roads, buildings, and sidewalks all come from geologic resources, and everything in our daily lives is affected by active geologic processes. We don’t have to go very far to see abundant examples of geologic resources and processes in action. Objectives 1) Go outside and use your geological and analytical skills. 2) Learn interesting information about rocks that you may see every day on campus. 3) Learn about several active geologic processes on our campus. 4) Observe how rocks are used effectively in art and as building materials. Materials Pencil Clipboard Wear appropriate clothes and shoes for going outside. We will go regardless of the weather, so dress for cold and wet if necessary. Prelab work (to be completed before lab begins) Review the Google Earth files provided on the Canvas site under Lab #5 (WWU placemark and the South Bellingham LiDAR overlay). In-Class Activities (due by the end of lab today) Stops are subject to change. Stop 1: Outdoor classroom on Sehome Hill Stop 2: Sehome Hill landslide behind Art Building Stop 3: Fisher Fountain Stop 4: Main library entrance Dark tiles under skybridge Outcrop next to skybridge Stop 5: Memory Walk and Old Main Stop 6: Avalanche victims’ memorial Stop 7: Edens Hall rock sequence Homework Activities (due the beginning of next lab) None Lab partners:__________________ ________________________ _____________________________ ________________________ _____________________________ ________________________ Name: __________________________ TA: ____________________________ Day: ___________ Time: __________

Lab #5: WWU Campus Geology Tour 81 Stop 1: Sehome Hill Outdoor Classroom 1. Do you think this rock is igneous, sedimentary or metamorphic? ___________________________________ 2. Pay close attention to rock grains and list their characteristics (e.g. size, roundness, sorting)? ______________ _________________________________________________________________________________________ 3. Identify this rock. _________________________________________________________________________ 4. This outcrop is part of the Chuckanut Formation. Based on your observations, make some specific interpretations about the possible depositional environments in which the outcrop in front of you formed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
