With reference to Deep-ocean polymetallic nodules, consider the follow...

Deep-ocean polymetallic nodules form on or just below the vast, sediment-covered, abyssal plains of the global ocean. Polymetallic nodules primarily consist of precipitated iron oxyhydroxides and manganese oxides, onto which metals such as nickel, cobalt, copper, titanium and rare earth elements sorb. The enormous tonnage of nodules on the seabed, and the immense quantities of critical metals that they contain, have made them a target for future mining operations. Hence, statement 1 is correct.
The chemical and mineralogical compositions of polymetallic nodules are primarily controlled by their formation process. A unique characteristic of deep-ocean nodules compared to terrestrial deposits is the presence of multiple commodities in one deposit; for example, nodules from the Clarion–Clipperton Zone contain Mn, Ni, Cu and Co.
Distribution:
- Nodules have been found in all the oceans and even in lakes. However, nodules of economic interest are more localized. Three areas have been selected by industrial explorers: the centre of the north-central Pacific Ocean, Peru Basin in the southeast Pacific Ocean and the centre of the north Indian Ocean. Hence, statement 2 is correct
