Plate Boundaries and Plate Interactions Goals • Classify and label the types of movement at plate boundaries, using a world map that shows relative plate motions • Identify the distribution of plates by means of the world map of relative plate motions • Describe the present plate-tectonic setting of your community, and infer possible past plate-tectonic activity based on your knowledge. • Divergent Plate Boundary • Convergent Plate Boundary • Transform Plate Boundary Think About It • Write a caption for this cartoon. • The most interesting ride on a plate would be the leading or trailing plate. Investigate page 79 • Answer Part C and Part D • Read Digging Deeper pg. 80-85 • Answer questions #1-7 on page 85 in your comp book. • No you don’t have write the questions in your comp book, but only if you write a complete answer. • Add the Geo words into your illustrated glossary. Divergent Plate Boundary • It’s a plate boundary where two plates move away from one another • Example: South American & African Plate Divergent Plate Boundary • Young divergence has thin or thinning crust and rift valleys • Example: Mid Ocean Ridge and East Pacific Rise Divergent Boundaries Convergent Plate Boundary • A plate boundary where two plates go toward each other • The denser crust will always subduct beneath the other crust. Sometimes these make ocean trenches. • Nazca plate & South American Plate Convergent Plate Boundary • If denser oceanic crust subbducts beneath continental crust, a volcanic chain – Ex) Andes or the Cascades Convergent Plates • The sinking material can partially melt. This makes volcanic island arcs. – Ex) Aleutian islands and Japan Convergent Plate Boundary When 2 continents collide that are both to light to subduct the crust is crumpled and uplifted to make great mountain chains – ex) Himalayas and Appalachian Transform Plate Boundary • When two plates move parallel from each other • San Andreas Fault • AKA: parallel slip San Andreas Fault • SAF is the boundary between the North American and Pacific plates. • The fault runs from the Gulf of Calif. NW to Mendocino County in N. California Transform Plate Boundaries Transform Plate Boundaries Homework • Visit the following website and record examples of each type of plate boundary into your comp book. • http://geology.com/plate-tectonics.shtml • Study for your quiz on Tuesday • Tectonic Setting for Volcanic Activity animations Warm-Up 1. Write a brief definition for each of the following terms and give an example of where you might find each: a) Divergent Plate Boundary b) Convergent Plate Boundary c) Transform Plate Boundary Warm-Up 1. Convergent boundaries can be in three different settings. What are they? 2. Name the 3 types of boundaries between lithospheric plates 3. What happens when two continent plates collide along a convergent plate boundary?
