1 Plate Boundaries and Plate Interactions

2 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.

3 Divergent Plate Boundary Convergent Plate Boundary Transform Plate Boundary

4 Think About It Write a caption for this cartoon. The most interesting ride on a plate would be the leading or trailing plate.

5 Investigate page 79 Answer Part C and Part D Read Digging Deeper pg Answer questions #1-7 on page 85 in your comp book. No you dont have write the questions in your comp book, but only if you write a complete answer. Add the Geo words into your illustrated glossary.

6 Divergent Plate Boundary Its a plate boundary where two plates move away from one another Example: South American & African Plate

7 Divergent Plate Boundary Young divergence has thin or thinning crust and rift valleysrift valleys Example: Mid Ocean Ridge and East Pacific Rise

8 Divergent Boundaries

9 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

10 Convergent Plate Boundary If denser oceanic crust subbducts beneath continental crust, a volcanic chain –Ex) Andes or the Cascades

11 Convergent Plates The sinking material can partially melt. This makes volcanic island arcs. –Ex) Aleutian islands and Japan

12 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

13 Transform Plate Boundary When two plates move parallel from each other San Andreas Fault AKA: parallel slip

14 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

15 Transform Plate Boundaries

17 Homework Visit the following website and record examples of each type of plate boundary into your comp book. Study for your quiz on Tuesday Tectonic Setting for Volcanic Activity animationsTectonic Setting for Volcanic Activity animations

18 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

19 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?
