Main Body
Important events like volcanism, earthquake, tsunami et are studied.
Importance of Oceanics information in geological Processes
Important Areas & events are studied in Geology [eg: circum pacific ring of fire shows high volcanism
Important circulations like ocean currents, Atlantic meridonic oceanic circulation (AMOC) et give valuable insight.
Major features of ocean floor include continental shelf and continental slope.
Significance in oceanography:
(A) Continental shelf
Repository of many mineral important oils & natural gas.
[eg: shale gases on continental shelf.
Crossing & Depositional activities
This is the area where many fossils and life-specimen can be found to study about it.
Place Deposits.
Exclusive Economic Zone is here only.
(B) Continental slope
The slope gives way to the high seas
(C) Continental rise
Important Ridges & volcanic mountains undermath
[eg: Mid oceanic ranges in Atlantic ocean.
(D) Abyssal plain
Are getting studied for knowing about different species living there
[eg: Bioluminescent species can be found.
