  1. 1. Interpreting a Plate Tectonic Map – Earth Science ExerciseNAME: ___________________________________________ DATE: _____________CLASS: _____________ TEACHER: ____________________________ Interpreting a Plate Tectonic Map Earth Science ExerciseIn this exercise you will interpret a Plate Tectonic Map Reference Table and answerquestions based on the chart. In order to complete this exercise you will need toopen the following Adobe Acrobat .Pdf file: Plate Tectonic Map Reference Table.You can print the reference map. It is on web page 5.Directions: Before you begin, be sure to notice the key at the bottom of the PlateMap. Understanding these symbols is critical to the completion of this assignment.Arrow directions will assist you in understanding the "direction of plate movement".For example, look at subduction and you will see arrows coming towards eachother. This means that at boundary locations represented by the subduction symbol,the tectonic plates are moving towards each other.Answer all questions placing your answers in the spaces provided.1. Describe the plate motion that occurs at a Subduction Zone. Geoteach.com _________________________________________________________________2. Using the terms: Subduction, Divergence and Transform Boundary, name the typeof plate motion that is occurring at the following plate boundaries: 2a. the Nazca and South American Plates _______________________________ 2b. the Antarctic and Indian-Australian Plates ____________________________ 2c. the Cocos and Caribbean plates ____________________________________ 2d. the Eurasian and Philippine Plates __________________________________ 2e. the Antarctic and Pacific Plates _____________________________________ 2f. the North American and Eurasian Plates ______________________________ 2g. the North American and African Plates _______________________________3. Describe the plate motion that is occurring at a Transform Boundary. _________________________________________________________________4. Find a Transform Boundary located within the Antarctic plate and state the name of the tectonic feature in this area. _________________________________________________________________ Assignment text was written by and is © L.

  2. 2. Interpreting a Plate Tectonic Map – Earth Science Exercise5. Describe the type of plate motion that occurs at a Zone of Divergence where plates are "rifting". _________________________________________________________________6. Find 3 locations where divergence is taking place. Name the RIDGE at each location. Also name the plates involved at each location. (There may be more than 2 plates for each ridge so look carefully). Location 1: Ridge: _____________________________ Plates: ___________________________________________________________ Location 2: Ridge: _____________________________ Plates: ___________________________________________________________ Location 3: Ridge: _____________________________ Plates: ___________________________________________________________7. Make a general statement about divergent boundaries with respect to their being Geoteach.com found in oceanic versus continental locations. _________________________________________________________________8. The San Andreas Fault is a tectonically active area in California that, in the past, has been the site of significant earthquake activity. In fact, the westernmost portion of California is slowly and gradually separating from the easternmost section. Find the San Andreas Fault on the Plate Map and answer the following questions: 8a. What type of Plate Boundary is the San Andreas Fault? _________________________________________________________________ 8b. Name the 2 plates interacting at the location of this fault. _________________________________________________________________ 8c. State the general direction that the westernmost portion of California is moving. _________________________________________________________________ 8d. State the general direction that the easternmost section portion of California is moving. _________________________________________________________________ Assignment text was written by and is © L.

  3. 3. Interpreting a Plate Tectonic Map – Earth Science Exercise9. The Hawaiian Island Chain: 9a. What type of tectonic feature is associated with the formation of and also the present day eruptions on the Hawaiian Islands? _________________________________________________________________ 9b. Is this a tectonic feature located at the boundary of 2 tectonic plates or is it located within a tectonic plate? _________________________________________________________________ 9c. Name the plate or plates involved. _________________________________________________________________ 9d. Is this an Oceanic or Continental location? _________________________________________________________________ 9e. State the approximate latitude and longitude (with units/labels) for the Hawaiian Islands. Geoteach.com _________________________________________________________________10. Find a Mantle Hot Spot that is located underneath a large continental plate. 10a. Name the Hot Spot: _____________________________ 10b. State its approximate latitude and longitude (with units/labels). _________________________________________________________________11. Iceland is unique in that it was formed from Hot Spot volcanism associated with a mid-ocean ridge that rose above the oceans surface. 11a. Name the ridge that formed Iceland. _______________________________ 11b. What type of plate movement is occurring at this location? _________________________________________________________________ 11c. State the approximate latitude and longitude of Iceland (with units/labels. _________________________________________________________________ Assignment text was written by and is © L.

  4. 4. Interpreting a Plate Tectonic Map – Earth Science Exercise12. A geologically active area where a rifting (spreading apart) of plates is presently taking place is the East African Rift Valley. Look at northeast Africa and, keeping in mind the symbol for "divergence", name the plates involved in this splitting of the African continent. _________________________________________________________________13. It is said that the East African Rift Valley is a product of a triple junction or, in other words, 2 separate rift zones which are dividing the African continent into 3 distinct areas. One of the rifts is located within the African Plate and is not a product of the 2 diverging plates you named above. On the Plate Map there is a symbol which indicates this other rift junction. Look at the map key and write the exact words that refer to and describe this intracontinental location. _________________________________________________________________14. Mount ST. Helens is a famous volcano located in the Cascades, a mountain range that extend north to south and which is located to the west of the Yellowstone Hot Spot. The volcano erupted in May 1980. Its activity can be Geoteach.com traced back to the tectonic activity of 2 plates located at a Subduction Zone. 14a. Name the 2 plates that would have been responsible for the formation of the Cascades and for the eruption of Mount ST. Helens. _________________________________________________________________ 14b. Which of these 2 plates is the one going under the other? (Look carefully at the Map Key). _________________________________________________________________15. State the latitude and longitude (with units/labels) for the southernmost and northernmost points of the Mid-Atlantic Ridge. Southern coordinates: __________________________________ Northern coordinates: __________________________________ This assignment was written by and is © L.
