Main Body

The configuration of ocean floor provides essential information about the geological processes that have shaped the earth's surface. Discuss the major features of the ocean floor & their significance to the study of oceanography.

Any

Ocean floors are case study to understand geological processes occurring over age.

Major feature of floor:

1Oceanic ridges: occurring along divergent boundaries eg: Atlantic ridge.
2Trenches: occurring along Convergent boundaries eg: Mariana trench along Pacific plate & North American plate
3Seamounts: There are underwater volcanic mountain
4Cruyots: There are seamounts with flat top.
5Abyssal plans: features plany where light can't reach.
6Continental slope: This connects Continental shelf & Abyssal planes.

Significance in Oceanography:

1Paleomagnetism: Rocks away from oceanic ridges & their properties explain geological time scale & magnitude.
2Plate tectonic movement can be inferred & also explains volcanisms & earthquakes eg: circumPacific rim.
3Mineral exploration: Polymidtic nodules carrying copper, manganese etc eg: Indian Ocean basin.
4Studying biodiversity underwater eg: coral reef study.
5Predicting disasters of features & volcanism.

India has launched deep Ocean mission to study Ocean deep & seabed features.
