Unique geomorphologic features in ocean basins
Continental rises
- Found seaward of continental rise
- Water depths usually about 3-4 km (5-10 km along ‘active’ continental margins)
- Average surface slope is ~1°
- Underlain by young sedimentary rocks that are continuous with those found in continental shelves
- Basement may be either continental rock (granites) or oceanic rock (basalts and gabbros)
