Name: ___________________________ Block: _____ Date: ____________________________________ EARTH SCIENCE 11 Chapter 13 Plate Tectonics Review Exercise 1: For each of the following, choose one of the four terms that best relates to the single term in the same way the pair of terms relate to each other. Circle the correct answer. 1. Rigid piece of curst : Plate Movement: Rising, sinking, tectonics, uplift 2. Lithosphere : Solid 3. Warm : Rising 4. Converging : Uplift Subduction: Trenches, volcanoes, rift valley, wrench fault 5. Converging : Uplift Mid-ocean ridge: Trenches, volcanoes, rift valley, wrench fault 6. Plate boundary: Earthquake Subduction zone: Uplift, rift valley, volcanoes, wrench fault 7. Shallow earthquake : Sliding Deep earthquake: Converging, diverging, sliding, subduction 8. Eroded sediment : Coastal Asthenosphere: Flexible, plastic, elastic, immoavable Cool: Uplift, downward, rising, sinking Scraped-off sediment: Deep-sea, volcanic, wave-built, precipitated Exercise 2: For each of the following, choose the phrase in Column B that best describes the term in Column A _____ 1. _____ 2. Column A Plates Lithosphere _____ 3. _____ 4. Asthenosphere Plate boundary _____ 5. _____ 6. _____ 7. Magnetic stripping Heat flow Mid-ocean ridge _____ 8. Converging boundary _____ 9.

Changes in magnetic polarity recorded in the lithosphere c. Zone where many volcanoes and earthquakes occur d. Zone where two plates are moving horizontally past one another e. Rigid moving pieces of Earth’s crust f. Zone where two plates are moving apart g. Zone where two plates are colliding and pushing a great mountain range upward h. Single solid layer of the crust and upper mantle approximately 100km thick i. Measure of the amount of heat leaving the lithosphere j. A crack or break in Earth’s crust k. A diverging boundary marked by a rift valley l. Plastic portion of the mantle below the lithosphere Name: ___________________________ Block: _____ Date: ____________________________________ EARTH SCIENCE 11 Exercise 3: Answer the following questions.
