Pacific Ocean
The Pacific Oceans natural resources include: oil and gas fields, polymetallic nodules, sand and gravel aggregates, placer deposits, and fish. Polymetallic nodules, also called manganese nodules, are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. Sand and gravel aggregates provide cement and concrete. Placer deposits are accumulations of valuable minerals formed by deposition of dense mineral phases in a trap site. Everybody of course, should know what oil and gas fields and fish are, I think its somewhat obvious.
