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.
What are manganese nodules examples of?
Manganese nodules are examples of polymetallic nodules found on the ocean floor, primarily composed of manganese and iron oxides, along with various other metals like copper, nickel, and cobalt. They form over millions of years through the accumulation of minerals precipitated from seawater. These nodules are significant for their potential as a resource for rare metals and their role in oceanic geology and ecology.
What does not affect ocean salinity?
Rainfall does not directly affect ocean salinity, as rainwater is freshwater and dilutes the salt content in the ocean. Other factors such as evaporation, ice formation, and river input can influence ocean salinity levels.
Why are nodules not mined for ores such as manganese and iron?
Nodules containing manganese and iron are found deep in the ocean floor, making it challenging and expensive to mine them. Additionally, the environmental impacts of deep-sea mining, such as disruption to marine ecosystems, make it a less attractive option compared to land-based mining.
What is the major source of oceanic salinity?
The major source of oceanic salinity is the dissolution of ions from rocks on land that are carried into the ocean by rivers. This process adds various salts to seawater, contributing to its overall salinity. Additionally, hydrothermal vents on the ocean floor can also introduce elements and minerals that affect salinity.
What ocean resource is not economically profitable to mine?
Manganese Nodules.
What ocean resource is currently not profitable to mine?
Manganese Nodules.

Manganese nodules are an example of what type of sediment?
Manganese nodules are an example of hydrogenous sediment, which forms directly from ocean water through chemical precipitation. They are typically found on the deep ocean floor.

Potato-shaped lump of minerals found in deep water?
Nodules of manganese are commonly found on the ocean floor.

How does salinity affect ocean life?
no you dident
What are five minerals that may be found in nodules?
Five minerals that may be found in nodules are manganese, iron, cobalt, copper, and nickel. These minerals are commonly found in nodules formed on the ocean floor.
How do hydrogenectic manganese nodule form?
Hydrogenetic manganese nodules form over millions of years through the precipitation of metals out of seawater onto small particles or other nodules on the ocean floor. Manganese and other metals accumulate on the nodules as a result of chemical reactions driven by the presence of hydrogen in the deep-sea environment. These nodules grow at very slow rates, about 1-10 millimeters per million years.
What mineral resources are found in or beneath the ocean?
Mineral resources found in or beneath the ocean include manganese nodules, cobalt-rich crusts, polymetallic nodules, and hydrothermal vents that contain minerals like copper, zinc, gold, and silver. These resources are being explored for their potential commercial value.
What is the way 25-cm manganese nodules form on the ocean floor?
it is either apatite, kimberlite magma precipitation minerals calcite or mica
