What are ways that the oozes and manganese nodules are different?
Oozes are deep-sea sediments composed of microscopic shells and organic matter, while manganese nodules are hard, mineral formations found on the ocean floor. Oozes are soft and can accumulate quickly, while manganese nodules grow slowly over millions of years. Oozes are primarily composed of calcium carbonate, while manganese nodules contain high levels of metals like manganese, iron, and nickel.
Do Manganese nodules do not accumulate below 4500 meters depth because the manganese minerals are highly soluble in seawater below that depth?
Yes, that is correct. Manganese nodules do not tend to accumulate below 4500 meters as the manganese minerals in the nodules become more soluble in seawater at greater depths. This leads to the dissolution of the nodules rather than their accumulation.
What is the example of authigenic sediment?
An example of authigenic sediment is manganese nodules, which form on the seafloor as a result of chemical precipitation of manganese and iron oxides. These nodules slowly grow over time by accumulating layers of material from seawater.
What are two minerals that make up nodules?
Two minerals that make up nodules are manganese (usually as manganese oxide) and iron (usually as iron oxides or hydroxides). These minerals precipitate out of seawater onto the seafloor, gradually forming into nodules over time.
How do manganese nodules affect the salinity of ocean water?
Manganese nodules do not directly affect the salinity of ocean water. Salinity is primarily influenced by factors such as evaporation, precipitation, and inputs from rivers and hydrothermal vents. While manganese nodules can impact the distribution of minerals in the ocean floor, they do not play a significant role in altering the overall salinity of the water.

Are manganese nodules examples of biogenous sediment?
No, manganese nodules are examples of hydrogenous sediment. They form through chemical precipitation in seawater, often around a nucleus like a shark tooth or a shell, rather than being produced by living organisms like biogenous sediment.

Yes, that is correct. Manganese nodules do not tend to accumulate below 4500 meters as the manganese minerals in the nodules become more soluble in seawater at greater depths. This leads to the dissolution of the nodules rather than their accumulation.

What ocean resource is currently not profitable to mine?
Manganese Nodules.
What ocean resource is not economically profitable to mine?
Manganese Nodules.
Both phosphorite and manganese nodules were first discovered by the?
HMS Challenger
What minerals can be found in Nodules?
oxides of manganese, nickel, copper and iron
How do manganese nodules form?
Manganese nodules form through precipitation of manganese and other minerals over long periods of time on the sea floor. These nodules grow layer by layer around a nucleus such as a shark tooth or shell, and can take millions of years to reach substantial sizes.

What industry uses iron manganese nodules?
none yet, but we need to start
