Types of Plate Boundaries

Please type your first and last name. 😊 1. What kind of plate boundary is shown in this picture? plates sliding past each other. a divergent boundary. a convergent boundary. a transform boundary. 2. Why does oceanic crust slide below the continental crust in a convergent boundary to create ocean trenches? Oceanic crust is less dense and more likely to be pushed back into the mantle. Oceanic crust is more plentiful and more likely to be available to slide in a convergent boundary. Oceanic crust is more likely to crumble under the pressure. Oceanic crust is more dense and more likely to be pushed back into the mantle. 3. Which of the following can be formed by a convergent boundary between two continental plates? Volcanic mountains Volcanic islands Mountain range valley 4. Plate tectonics is the theory that the Earth's crust _. is stationary except for the continents that move through the ocean. is broken into pieces that move around. is broken into stationary pieces. moves around on the surface of the Earth in one piece. 5. Which of the following statements BEST categorizes a transform boundary? It is tectonic movement as a result of building pressure, resulting in an ocean trench. It is tectonic movement as a result of building pressure, resulting in an earthquake. It is tectonic movement as a result of mountain formation. 6. What is happening at the area marked by the red dot? subduction rift valley mountain convection 7. Where is new lithosphere created? divergent boundary between continental plates convergent boundary between continental plates divergent boundary between oceanic plates transform boundary between a continental plate and an oceanic plate 8. Refer to the diagram below.What type of boundary is occurring between the South American and the African plate? convergent boundary transform boundary divergent boundary 9. Refer to the diagram below.What type of boundary is occurring between the Cocos and the Caribbean plates? convergent boundary transform boundary divergent boundary 10. Refer to the diagram below.What type of boundary is occurring between the Pacific and North American plates (focus on the west coast of the United States)? convergent boundary transform boundary divergent boundary 11. Refer to the diagram below.What landforms are likely to form along the west coast of South America? mountains trenches volcanic mountain range valleys 12. Which continental plate is diverging from the African plate? What landform is forming there? 13. Refer to the image below. Which of the following is occurring at the subduction plate? ridge-push mantle convection slab pull 14. Refer to the image below. Which of the following is occurring at the oceanic spreading ridge? ridge-push mantle convection slab pull 15. Refer to the image below. At what type of boundary do trenches form? convergent transform divergent 16. The theory that states that pieces of Earth's crust are in constant, slow motion is the theory of... continental drift seafloor spreading plate tectonics Pangaea 17. What is the source of energy that drives plate movement? convection currents in the mantle movement of liquid metal in the outer core solid inner core differences in air pressure 18. During sea floor spreading, molten material rises up from the mantle and cools and hardens forming what type of rock? sedimentary metamorphic igneous magma 19. What does the lithosphere "float" on top of? water atmosphere asthenosphere upper mantle
