East African Rift:
At a Convergent Plate Boundary two colliding plates buckle the edge of one or both plates forming a rugged mountain range.Rugged Mountains are above sea level. An example of a rugged mountain is Mount Everest. Under the oceans one plate bends the other down into a deep seafloor trench. A deep sea floor trench is located in the deeper parts of the ocean. An example is Mariana Trench.
At a Transform Plate Boundary natural or human made sturctures that cross a transform boundary are split. In land Rocks that are on the boundary are pulverized or crushed as the plates grind past each other. Transform faults stay in the same location. An example of a fault is the San Andreas Fault. In the ocean it creates a linear fault valley or undersea canyon. An undersea canyon is a steep valley on the sea floor.
