Extracted text: volcanic arc Mantle Mantie ocean PLATE B Outer Core Inner Core PLATE A Figure 3. Movement of Magma in the Mantle Figure 2. Colliding between Oceanic and Continental Plates 17. Which of the following can be explained at Point A in Figure 3? A. Plates move apart and an oceanic ridge is formed B. Plates move past each other sideways. C. Plates are not moving. D. Plates move toward each other and a volcano is formed. 12. What do you expect to happen after a trench is formed during the subduction of a plate? A. A volcanic arc C. A second trench D. An oceanic ridge B. A mountain range 13. In the figure above, the subducted plate continually goes down and reaches at the inner part of earth, what event could eventually take place? 18. What geologic event is most likely to happen when two plates slide past each other? A. Earthquake B. Mountain formation A. Earthquake B. Island arc C. Rift valley D. Sea trench C. Rift valley formation D. Volcanic eruption 14. What is the topographic feature at Point X called and to what type of plate boundary is it? AB C A. Earthquake, Transform fault B. Island arc, Convergent C. Rift valley, Divergent D. Sea trench, Convergent E F 15. During a field trip, unexpectedly you find a rift valley right in the middle of an island. What type of plate boundary exists on that island? Figure 4. Blocks representing Tectonics Plates A. Convergent B. Divergent C. Transform fault D. Normal fault 19. In Figure 4 above, what type of plate boundary is formed between Block C and Block 16. What type of plate boundary is most likely to occur at point A in Figure 3? D? A. Transform B. Divergent C. Reverse D. Convergent A. Convergent B. Divergent C. Transform-Fault D. Convection 20. What geologic event may occur between Block C and Block D? A. Earthquake B. Island arc C. Oceanic ridge D.
