Plate Tectonics Test Study Guide Continental Plates (CP): Less dense than oceanic plates Oceanic Plates (OP): Heavier than continental plates Strike-Slip Boundary: two plates grind together and slip past each other horizontally. Subduct: to dive down Trench: deep places on the ocean floor where the edge of one plate subducts under the edge of another plate. Converge: move together Diverge: move apart Mid-ocean ridges: cracks on the sea floor where sea floor is spreading apart Earthquakes are most common at the boundaries, or edges, of the tectonic plates.. In fact, scientists have located the boundaries of tectonic plates by mapping the location of earthquakes all over the world. Type of plates Type of What is made Destructive or Earthquakes Volcanoes (if movement Constructive yes type) OP-OP converge Trench Destructive yes Yes Ocean Volcano OP-OP diverge Mid-ocean Constructive yes Yes ridges Ocean Volcano OP-CP converge Trench Destructive yes Yes Continental volcano CP-CP converge Mountains Constructive yes no Any type Slip-Stike Nothing (stays Neither yes no about the same elevation)
