Question

Quizplus · Accepted Answer

Oceanic rises are segments of the oceanic ridge system that have gentler slopes due to faster rates of seafloor spreading. This process leads to a buildup of new crust, causing the ridge to rise and flatten out. Deep-sea trenches, on the other hand, are narrow, steeply-sided depressions in the seafloor that form at convergent plate boundaries, where one tectonic plate is being forced beneath another. Fracture zones are areas where tectonic plates are sliding past each other, often marked by prominent transform faults.
