Main Body
The major features of ocean floor are -
At the divergent oceanic boundaries -
(Eg. Atlantic ridge
At the convergent oceanic-continental boundaries -
(Eg. Mariana trench
At the convergent oceanic-oceanic boundaries -
(Eg. Pacific ring of fire - Hawaii hotspot
At the continental boundaries -
(Eg. Mexico, Chile

(Eg. convergent-convergent
sea floor spreading theory
Further they also help in -
(Eg. Polymetallic nodules
Owing to this importance Japan had taken up the project of seafloor mapping by 2030.
Conclusion
These benefits render the problem of tradeoff between economic growth and environment. The solution lies in usage of advanced technology in exploration as done by USA.
