The most likely place to find abundant manganese nodules is on the:
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. The core may be microscopically small and is sometimes completely transformed into manganese minerals by crystallization. Authigenic sediment, deep-sea sediment that has been formed in place on the seafloor. The most significant authigenic sediments in modern ocean basins are metal-rich sediments and manganese nodules. Metal-rich sediments include those enriched by iron, manganese, copper, chromium, and lead.

Abyssal clays are more abundant in the Pacific than the Atlantic because calcareous oozes dissolve before reaching the sea floor in the latter ocean basin. Based on this data, choose the statement that offers the best explanation for the differences in sediment abundance between the Atlantic and Pacific basins. Polymetallic nodules are rounded accretions of manganese and iron hydroxides that cover vast areas of the seafloor, but are most abundant on abyssal plains at water depths of 4000-6500 metres. Abyssal clays are more abundant in the Pacific than the Atlantic because calcareous oozes dissolve before reaching the sea floor in the latter ocean basin.

The chemical composition of nodules varies according to the kind of manganese minerals and the size and characteristics of the core. Those of greatest economic interest contain manganese (27-30%), nickel (1.25-1.5 %), copper (1-1.4 %) and cobalt (0.2-0.25 %).
