Ch. 2 Activity: Identifying Plate Boundaries Answer the following questions to test your knowledge of plate boundaries and tectonic hazards. This activity will count for up to 8 activity points.

1. The following map shows the world's key lithospheric plates. Numbers on the map refer to key plate boundaries, where plates are moving in relation to each other. These boundaries can be either convergent, divergent or transform. Juan de Fuca plate Pacific plate Cocos plate North American plate Nazca plate Scotia plate Caribbean plate 2. South American plate Eurasian plate Arabian plate African plate Antarctic plate Philippine plate Australian-Indian plate Pacific plate In relation to each of the locations 1-3 listed below answer the following questions: Location 1: Intersection between the Arabian Plate and the African Plate. Location 2: Intersection between the Nazca Plate and the South American Plate. Location 3: Intersection between the Australian-Indian Plate and the Eurasian Plate. a) What type of boundary is this and how do the plates move in relation to each other? b) What are the key landforms you would you find at this plate boundary? c) What are the key tectonic hazards that are associated with this boundary? 2. The image on the left below is a satellite photograph looking down on a coastal area in northern California with distinctive features on either side of the bay in the centre (see point 4 on the map above for the approximate location). Most of the bay area consists of marine sedimentary rocks that originated in the region. The image on the right shows an outcrop of granite that is found to the west of the bay that matches rock formations found in mountains more than 300 miles to the south. Drawing on your knowledge of plate boundaries and tectonics in this region, explain why this granite outcrop is found here even though it originated elsewhere.
