Question Q.4GS1GS1
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
Oceans comprise many 90% area on the Earth's surface and 93% of the available water on the earth.

The configuration of ocean floor comprises of varied landforms and provides essential information about geological processes like:
1Depositional landforms → Shelfs, aseisf
2Volcanism → mid oceanic ridge
3Sea-floor spreading → Crust formation
4Deep sea earthquakes → As ring of fire
5Plate tectonics → Different places
Significance:
1Crustal formation → Recent formed and old is concerned
2Economic significance → Banks → fishing grounds, Board gas, oceanography
3Polyminerallic nodules and rare earth minerals
4Trenches → Help in deep sea digging projects
5Mid oceanic ridges → Volcanism, earth material & formation
4Trenches → Long, narrow & deep fissures → Mariana trench
5Abyssal plains → Most extensive plains, associated with landforms like mounts, buoyts
6Mid oceanic ridge → Volcanic eruptions due to a floor/floor boundary associated with divergent plate boundaries
Significance
1Crustal formation → Newer formed and old is concerned
2Economic significance → Banks → fishing grounds, Board gas, oceanography
3Polyminetallic nodules and rare earth minerals
4Trenches → Help in deep sea digging projects
5Mid oceanic ridges → Volcanism, earth material & formation
4Trenches → Long, narrow & deep fissures → Mariana trench
5Abyssal plains → Most extensive plains, associated with landforms like mounts, buoyts
6Mid oceanic ridge → Volcanic eruptions due to a floor/floor boundary associated with divergent plate boundaries.
Significance
1Crustal formation → Newer formed and old is concerned
2Economic significance → Banks → fishing grounds, Board gas, oceanography → Water/space, scuba diving
3Polyminetallic nodules and rare earth minerals
4Trenches → Help in deep sea digging projects
5Mid oceanic ridges → Volcanism, earth material & formation
