Read the extract and answer the questions that follows:
Minerals are usually found in “ores”. The term ore is used to describe an accumulation of any mineral mixed with other elements. The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable. The type of formation or structure in which they are found determines the relative ease with which mineral ores may be mined. This also determines the cost of extraction. It is, therefore, important for us to understand the main types of formations in which minerals occur.
Minerals generally occur in these forms:
(i) In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called veins and the larger are called lodes. In most cases, they are formed when minerals in liquid/molten and gaseous forms are forced upward through cavities towards the earth’s surface. They cool and solidify as they rise. Major metallic minerals like tin, copper, zinc and lead etc. are obtained from veins and lodes.
(ii) In sedimentary rocks a number of minerals occur in beds or layers. They have been formed as a result of deposition, accumulation and concentration in horizontal strata. Coal and some forms of iron ore have been concentrated as a result of long periods under great heat and pressure. Another group of sedimentary minerals include gypsum, potash salt and sodium salt. These are formed as a result of evaporation especially in arid regions.
(iii) Another mode of formation involves the decomposition of surface rocks and the removal of soluble constituents, leaving a residual mass of weathered material containing ores. Bauxite is formed this way.
(iv) Certain minerals may occur as alluvial deposits in sands of valley floors and the base of hills. These deposits are called ‘placer deposits’ and generally contain minerals, which are not corroded by water. Gold, silver, tin and platinum are most important among such minerals.
(v) The ocean waters contain vast quantities of minerals, but most of these are too widely diffused to be of economic significance. However, common salt, magnesium and bromine are largely derived from ocean waters. The ocean beds, too, are rich in manganese nodules.
Answer the following MCQs by choosing the most appropriate option.
Q. The ocean beds, too, are rich in ______________ nodules.
  • a)

Manganese nodules are pebbles or stones about the size of walnuts that are built of onion like layers of manganese and iron oxides. Minor constituents include copper, nickel, and cobalt, making the nodules a potential ore of these valuable elements.

Understanding Manganese Nodules
The question relates to the mineral wealth found in ocean beds, specifically focusing on manganese nodules. Here’s a detailed explanation of why the correct answer is option 'C' - manganese.
What are Manganese Nodules?
- Manganese nodules are rock concretions that are typically found on the ocean floor.
- They are composed mainly of manganese and iron, along with small amounts of nickel, copper, and cobalt.
- These nodules form over millions of years through the precipitation of minerals from seawater.
Significance of Manganese Nodules
- Manganese nodules are considered valuable due to their high mineral content, especially manganese, which is essential for steel production and other industrial applications.
- They are found in deep-sea environments, often at depths ranging from 4,000 to 6,000 meters.
Comparison with Other Minerals
- While ocean waters contain various minerals, most are too diffuse to be economically viable.
- Common salt, magnesium, and bromine are derived from ocean water but not in the concentrated form found in nodules.
- In contrast, manganese nodules present a concentrated source of manganese and other metals, making them of significant economic interest.
Conclusion
- The ocean beds are indeed rich in manganese nodules, which is why option 'C' is the correct answer.
- Understanding the formation and significance of these nodules highlights their role in both ecology and industry, emphasizing their importance in marine mineral resources.
