Segments of the oceanic ridge system that are gentler and less rugged in slope due to faster rates of seafloor spreading are called . A) deep-sea trenches
B) fracture zones
C) oceanic rises
D) convergent plate boundaries
E) transform faults

C) oceanic rises

The oceanic ridges and the oceanic rise are the gentle and the fast and sloping parts of the oceanic ridges and they are caused by the convergence of the two plates and thus result in the formation of the seafloor subducts and the island arcs.
