Oceanic Ridge A has slow spreading rates of 2-5 cm/yr. Oceanic Ridge B has intermediate spreading rates of 6-9 cm/yr. Oceanic Ridge C has fast spreading rates of 10-11 cm/yr
Compare and contrast the topography and structure that would be present at all three spreading centers.
What will be an ideal response?
Answer: Slow-spreading centers like Ridge A will have prominent rift valleys and rugged topography. Intermediate spreading centers like Ridge B will have shallower rift valleys and more subdued topography. Fast-spreading centers will generate rises rather than ridges, with more gradual profiles and less rugged terrain.
