Types of Coal for Commercial Use

When it comes to commercial use, the most popular type of coal is bituminous coal. Here is a detailed explanation of the different types of coal and why bituminous coal is the preferred choice:

1. Bituminous Coal

• Bituminous coal is the most commonly used type of coal for commercial purposes.


• It is a dense and highly carbonaceous coal that contains a relatively high percentage of carbon and has a higher energy content compared to other types of coal.


• Bituminous coal is widely used in electricity generation, as a fuel for industrial boilers, and for the production of coke, which is used in steel production.

2. Anthracite Coal

• Anthracite coal is the highest rank of coal and has a very high carbon content.


• It is known for its high energy content and low impurities.


• While anthracite coal has excellent heating properties, it is less commonly used for commercial purposes due to its limited availability and higher cost.

3. Lignite Coal

• Lignite coal, also known as brown coal, is a low-ranking coal with a high moisture content and lower carbon content compared to bituminous and anthracite coal.


• It has a lower energy content and is often used for electricity generation in power plants located near the coal mines.


• However, lignite coal is not as popular for commercial use as bituminous coal due to its lower energy content and higher moisture content, which makes it less efficient for many industrial applications.

Therefore, the most popular type of coal for commercial use is bituminous coal, primarily due to its high energy content, availability, and suitability for various industrial applications.

Minerals are deposited and accumulated in the horizontal strata of which of the following rocks:

The correct answer is A: Sedimentary rocks. Minerals are typically deposited and accumulated in the horizontal strata of sedimentary rocks due to the following reasons:
1. Formation: Sedimentary rocks are formed from the accumulation and consolidation of sediments, which can include mineral particles.
2. Transportation: Minerals can be transported by wind, water, or ice and eventually settle in horizontal layers.
3. Deposition: Sedimentary rocks are formed through the process of deposition, where sediments settle and accumulate over time. As the sediments settle, minerals can become trapped within the layers.
4. Layering: Sedimentary rocks often exhibit distinct layering or stratification, with each layer representing a different period of deposition. Minerals can be concentrated within specific layers.
5. Cementation: Over time, the sediments in sedimentary rocks can undergo cementation, where minerals act as a natural binder, holding the particles together. This cementation process can further concentrate minerals within the rock.
In summary, sedimentary rocks are the primary rocks where minerals are deposited and accumulated in horizontal strata due to the processes of formation, transportation, deposition, layering, and cementation.

Best Quality of Iron Ore:
- The best quality of iron ore is Magnetite.
- Magnetite is a type of iron ore that is black or brownish-black in color.

Answer:

The larger occurrences of minerals in igneous and metamorphic rocks are called lodes.

Explanation:

When it comes to the larger occurrences of minerals in igneous and metamorphic rocks, the term used is lodes. Lodes are mineral deposits that are found in veins or masses within the host rock.

Here is a breakdown of the different options:

• Veins: Veins are mineral deposits that occur in fractures or cracks within rocks. They are usually narrow and linear.


• Lodes: Lodes are larger mineral deposits found in veins or masses within the rock.


• Beds: Beds are layers of rock or sediment that accumulate horizontally over time. They are not typically associated with mineral deposits.


• Layers: Layers refer to the horizontal arrangement of rocks or sedimentary deposits. They are not specifically related to the occurrence of minerals.

Therefore, the correct answer to the given question is option b. Lodes.

Factors responsible for the sugar mills to shift and concentrate in the southern and western states of India:

A: Sugarcane is bulky raw material:

• Sugarcane is a bulky raw material that requires significant transportation and storage facilities.


• Transporting sugarcane over long distances is not cost-effective due to its bulkiness and perishable nature.


• Therefore, sugar mills tend to be located closer to the sugarcane-producing regions to minimize transportation costs and ensure the timely processing of the raw material.

B: The sucrose content reduces with distance:

• The sucrose content in sugarcane tends to reduce as the distance between the cultivation area and the processing mills increases.


• Transporting sugarcane over long distances may result in a decrease in sucrose content, affecting the quality and yield of sugar production.


• By concentrating sugar mills in the southern and western states, which are closer to the sugarcane fields, the sucrose content can be better preserved, leading to higher-quality sugar production.

C: The cane produced has higher sucrose content:

• The sugarcane produced in the southern and western states of India is known to have a higher sucrose content compared to other regions.


• This higher sucrose content makes the sugarcane from these states more suitable for sugar production.


• As a result, sugar mills tend to shift and concentrate in these states to take advantage of the higher sucrose content in the cane, leading to more efficient and profitable sugar production.

D: The cooperatives are not successful:

• The cooperative system of sugar production, where farmers collectively own and operate sugar mills, has not been as successful in some regions of India.


• This may be due to various factors such as lack of proper management, financial constraints, or disputes among members.


• As a result, sugar mills in these regions may not be able to operate efficiently and may face challenges in sustaining their production.


• In contrast, the southern and western states have seen more success in the cooperative model, leading to the concentration of sugar mills in these regions.

Overall, while factors such as the bulky nature of sugarcane and the challenges of long-distance transportation play a role in the concentration of sugar mills in the southern and western states of India, the higher sucrose content in the sugarcane produced in these states is a significant factor driving this shift.

Answer:
The nonconventional source of energy harnessed in the Parvati Valley near Manikaran in Himachal Pradesh is Geothermal Energy.
