DO NOT WRITE ON THIS PAPER Plate Tectonics Unit 6 Lesson 4 Key Concepts Choose the letter of the best answer. 1. Scientists think the continents once formed a large, single landmass that broke apart, and the continents slowly drifted to their present locations. What is the name given to this hypothesis? 4. The Rocky Mountains formed when the Pacific plate collided with the North American plate. Which of the following terms describes this process? A. ridge push A. continental rise B. divergent boundary B. continental drift C. transform boundary C. continental shelf D. convergent boundary D. continental slope 2. Florida is not close the edge of a tectonic plate. Therefore, which one of the following features does not exist in or beneath Florida? 5. What are the mechanisms that have been proposed to explain the movement of Earth’s tectonic plates? A. slab pull and sea-floor spreading A. crust B. mantle convection and continental drift B. mantle C. mantle convection, ridge push, and slab pull C. tectonic plate D. sea-floor spreading and continental drift D. tectonic plate boundary 3. The Red Sea formed as the African Plate moved apart from the Arabian Plate. Which type of boundary was involved in the formation of the Red Sea? A. transform boundary B. divergent boundary C. stationary boundary D. convergent boundary
