Themes of the Week:

The geologic themes for this week include the basic concepts of plate tectonics and the rock cycle.

To fully explore these themes you will:

• List the main points of the theory of plate tectonics and define lithosphere, asthenosphere, and tectonic plate.
• Name the three major types of tectonic plate boundaries and describe what happens geologically at each type.
• Describe the predominate types of faults, earthquakes, volcanoes, metamorphism, and sediments that occur at each type of plate boundary.
• Draw and label a plate tectonic map, including proper map symbols for each type of plate boundary and the location of a volcanic arc in relation to a subduction zone.
• Draw and label a plate tectonic map of the Pacific Northwest, including plate names, plate boundary names, and location of the Cascade volcanic arc in relation to plate boundaries.
• Draw, label, and explain the rock cycle, including the origins of volcanic and plutonic igneous rocks, clastic and chemical sedimentary rocks, and regional and contact metamorphic rocks.
• Identify where the nine representative rock types from the Pacific Northwest fit into the rock cycle.

By completing the following:

1. Read Lecture 4-Plate tectonics and the rock cycle along with its linked Basics and Focus pages and refer to them in your assignments.
2. Participate in the Week 4 Discussion in the online classroom. See Weekly Discussion Rubric
3. Read #4 Lab Assignment. Complete Lab Assignment #4 by:
   1. submitting the Lab #4 answer form in the online classroom
   See Lab Rubric
4. Take Quiz #4 in the online classroom. See the Weekly Quiz Rubric.
5. At the end of the week, compose a summary of the main things you learned about the geology of the Pacific Northwest and post it in the online classroom Week 4 Summary. See the Weekly Summary Rubric.
