Main Body
Ocean Bottom Relief
(A) major features
1Continental shelf => adjacent part of the continent. Surface between the continental & oceanic margins.
2Continental slope => higher slope gradient, covers 3-7% of OBR
3Continental rise => covered with marine and terrigenous sediments => important to understand the mineral composition of ocean floor.
4Abyssal plains => vast, extensive plane that are marked off several other features.
5Oceanic trenches => formed at zone of convergent place boundaries. Validate Hardy Hess's sea floor spreading theory. eg: Trench
6Mid-oceanic ridges => formed near divergent plate boundaries => basaltic cores of lava.
eg: Azores Island
(B) Secondary features
(a) Guyots
(b) Sea Mounts => formed due to evolution of mid-oceanic ridges.
(c) Knolls
=> continental shelf, OBR
=> continental slope
=> continental Rise [illegible]

Therefore, ocean configuration affects the surfacial and sub-surfacial movement of water to explore the OBR. Margen-6000 is scheduled to map ocean floor.
