Why are minerals nodules that are found on the ocean floor considered a nonrenewable resource?
Mineral nodules on the ocean floor are considered a nonrenewable resource because their formation takes millions of years through geological processes, making them extremely slow to replenish. Once harvested, the extraction of these nodules can deplete the resource significantly, as they do not regenerate at a rate that can keep up with human consumption. Furthermore, the environmental impact of mining these nodules can lead to irreversible damage to marine ecosystems, further emphasizing their nonrenewable nature.

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.
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.
Lumps of minerals on the ocean floor are called?
Nodules...
What ocean resource is not economically profitable to mine?
Manganese Nodules.
What ocean resource is currently not profitable to mine?
Manganese Nodules.
Which resource of the ocean floor could someday be an economical source of many metals including copper nickel and cobalt?
Polymetallic nodules are a potential economical source of metals like copper, nickel, and cobalt on the ocean floor. These nodules are potato-sized accretions of minerals that contain high concentrations of valuable metals, making them an attractive resource for future mining operations.
What minerals can be found in Nodules?
oxides of manganese, nickel, copper and iron
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.
Potato-shaped lump of minerals found in deep water?
Nodules of manganese are commonly found on the ocean floor.
How are nodules similar to gemstones?
Nodules and gemstones are both mineral formations that can be found in the Earth's crust. They are both composed of minerals and can have valuable or aesthetic qualities. However, gemstones are typically more highly prized for their beauty and rarity, whereas nodules may be of more scientific or industrial interest.
Are mineral nodules on the ocean floor non living resources?
well yes even though they DONT move there alive and are a living resource
What is the way 25-cm manganese nodules form on the ocean floor?
it is either apatite, kimberlite magma precipitation minerals calcite or mica
