Themes of the Week:

Volcanoes and rocks are the themes this week. We will look at the different types of volcanoes and examine the types of magmas, lavas, and eruption styles associated with each. We will explore the extent to which volcanism has created the rocks and shaped the landscapes of the Pacific Northwest. We will also begin learning to identify rocks this week, starting with igneous rocks.

To fully explore these themes you will:

• Describe the four major types of volcanic activity that have shaped the geologic history of the Pacific Northwest: formation of composite cones, formation of shield volcanoes, formation of calderas and formation of flood basalt landscapes.
• Show on a map the location of the major types of active volcanoes in the Pacific Northwest.
• Explain how the different types of volcanic activity in the Pacific Northwest are related to different types of magma, different styles of eruption, and different types of rock.
• Recognize a composite cone, a shield volcano, and a cinder cone.
• Begin to identify nine representative rock types from the Pacific Northwest.

By completing the following:

1. Read Lecture 3-PNW volcanism and introduction to rocks & minerals along with its linked Basics and Focus pages and refer to them in your assignments.
2. Participate in the Week 3 Discussion in the online classroom. See Weekly Discussion Rubric.
3. Read #3 Lab Assignment. Complete Lab Assignment #3 by:
   1. if you wish, discussing with other students in the online classroom how to identify the nine types of rocks from your lab kit
   2. submitting the Lab #3 answer form in the online classroom
   See Lab Rubric
4. Take Quiz #3 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 3 Summary. See the Weekly Summary Rubric.
