1 Crustal Features and plate boundaries

2 Trench Definition: A deep depression of the sea floor caused by subduction of one plate under another. Boundary Type: Convergent

3 Rift zones Definition: An area in the middle of a continental plate where the plate is beginning to separate. A large valley will form in the area as the crust thins. Boundary Type: Divergent

4 Oceanic ridges Definition: Underwater mountain ranges where the crust is spreading apart creating new ocean floor. Boundary Type: Divergent

5 Underwater mountain ranges
Definition: Long, continuous volcanic chain of various mountains. Boundary Type: Divergent

6 Mountain ranges on land
Definition: A series of mountains that are close together and rise 300 m (1000 ft.) above its surrounding area. Boundary Type: Convergent

7 Ring of fire Definition: An area that is surrounding the Pacific Ocean that is comprised of multiple chains of volcanic islands. The area also has an abundance of volcanic activity. Boundary Type: Convergent

8

9 fault Definition: A crack in the Earth’s crust where rocks slide past one another. Different types of faults form based on direction of plate movement. Boundary Type: Divergent, Convergent, Transform
