Question

What do manganese nodules, metal sulfides, and evaporites all have in common?

A. They all are restricted to regions of high evaporation overlying the continental shelf.
B. They all precipitate from water oversaturated in their respective minerals.
C. They all form at deep-ocean sites where lithogenous sediments are rare.
D. They all form from chemical reactions modified by living organisms.
E. They all contain commercially valuable metals that are collected from the sea floor.

Answer 1

Manganese nodules, metal sulfides, and evaporites are all chemical sedimentary rocks formed through different processes.

Step-by-step explanation:

Manganese nodules, metal sulfides, and evaporites all have in common that they are all chemical sedimentary rocks formed through different processes. Manganese nodules are formed by the precipitation of manganese and other metals from seawater over a long period of time. Metal sulfides are formed when minerals containing sulfide ions react with metal ions in hydrothermal vents. Evaporites are formed when water evaporates, leaving behind the dissolved chemicals as deposits.
