Convergent movement occurs when the plates move toward each other and collide. Convergent plate boundaries are the sites of trenches, island arc volcanoes, earthquakes, folded mountains, and volcanoes at continent-ocean boundaries. When plates have convergent movement, the solid rock is moved upward in what looks like rolls or rounded layers. By looking at the side of a mountain and seeing layers of rock in joined rounded layers, you can identify a mountain made by convergent movement of plates. Transform movement occurs when plates slide horizontally past each other.
Earthquakes occur at transform plate boundaries.
Transform boundaries are often identified as fault lines. Mountains are formed from all three kinds of plate movements. When plates have divergent movement and pull apart, molten rock can move into the space and form mountains. These are seen as mountains formed from volcanoes. Plate movements cause push and pull stresses in the crust that are relieved by sudden breaks along faults.
