1. Activity 44

2. Challenge: How can you use earthquake and volcano data to map the earth’s plates? Key Vocabulary: Lithosphere Plates Glue in SS 44.1 Read the Introduction on page D-35!

3. Remember that Continental Drift only referred to the movement of the continents. Plate Tectonics refers to the movement of lithospheric plates These plates include the earth’s crust and extend down into the uppermost part of the upper mantle.

4. They represented continents! Glue in SS 44.1 “Anticipation Guide: Mapping Plates” Record if you agree or disagree with each statement by placing a “+” or a “-” in the BEFORE column.

5. Glue in SS 44.2 “Plate Boundaries” and follow steps #1-10 When you have completed the activity, go back to SS 44.1 and complete the AFTER column Then answer Analysis Questions 1, 3, 4, and 5 in your notebooks

6. 1.Most continents and plates have different sizes and shapes. Several plates contain entire continents and the adjacent ocean floor, such as the African plate, and are much larger than the continent itself Eurasia is made up of several plates, including the Indian, Arabian, and part of the North American plate Several (oceanic) plates are smaller than continents (such as the Caribbean and Philippine plates) The Australian continent appears to be about one-third of the sixe of the plate that it is a part of and the boundary edges are very different

7. 3.Earthquakes and volcanoes occur more frequently along plate boundaries than on other parts of the earth’s surface. In this activity, you used earthquake and volcano data to plot plate boundaries.

8. 4.You would predict that Washington would be at a greater risk of earthquakes because is it closer to a plate boundary than Texas

9. 5.India is a part of the Indian plate, while most of Eurasia is part of the Eurasian plate. Since these continents are a part of two different plates, they moved separately over the surface of the earth. Having a separate puzzle piece for India meant that the individual movement of both of these plates could be modeled in Activity 40.
