The configuration of the ocean floor provides essential information about the geological processes that have shaped the Earth's surface. Discuss the major features of the ocean floor and their significance in the study of oceanography.
Introduction
Ocean floor consist of 70% of total world surface, which include various features like continental shelf c. slope, continental rise, trenches, sea mount mid-oceanic ridge etc.

Major features -
Significance in study of oceanography -
1. The age of ocean can be found through paleomagnetism - parallel band of rocks on sea-floor.
2. Helps study various ocean deposits - help to interpret bio-geography of ocean.
3. Helps in studying geological history - eg Gondwanaland separation along the ridges due to divergence.
4. Help study marine resources - eg Hydro-thermal vents -> source of sulphides & polymetallic nodules.
5. Helps study the tides, ocean currents and how they are impacted by ocean configuration.
With development of new technology, the entire ocean floor is being mapped. They will further help understand various phenomenon under ocean.
Conclusion
With development of new technology, the entire ocean floor is being mapped. They will further help understand various phenomenon under ocean.
