Low-grade brown coal is called

Detailed Solution for Test: Minerals & Energy Resources - 3 - Question 2
Low-grade brown coal is called

Low-grade brown coal is called lignite.


Explanation:

Low-grade brown coal, also known as lignite, is a type of coal that is characterized by its low carbon content and high moisture content. It is considered the lowest grade of coal and is typically brown or black in color.


Here are some key points about lignite:


- Lignite is formed from peat, which is partially decayed plant material.
- It has a relatively low energy content compared to other types of coal.
- Lignite is mainly used for electricity generation and as a fuel for industrial processes.
- It is more abundant than other types of coal and is found in large deposits around the world.
- Lignite is often used in power plants that have specialized equipment to handle its high moisture content.
- It is less efficient and produces more emissions when burned compared to higher-grade coals.
- Lignite is typically mined using open-pit mining methods.

In summary, low-grade brown coal is known as lignite, and it is characterized by its low carbon content and high moisture content.

In igneous and metamorphic rocks, minerals may occur in the ..........  
(i) Cracks
(ii) Crevices
(iii) Faults or joints
(iv) Beds

Detailed Solution for Test: Minerals & Energy Resources - 3 - Question 7

In igneous and metamorphic rocks, minerals may occur in various locations within the rock formation. The minerals can be found in:
Cracks:
- Cracks or fissures within the rock provide spaces for minerals to accumulate.
- These cracks can be formed due to cooling and contraction of the rock or due to tectonic forces.
Crevices:
- Crevices are narrow openings or gaps within the rock.
- These gaps can be formed by weathering and erosion processes or by the movement of rock layers.
Faults or joints:
- Faults and joints are fractures in the rock where there has been displacement.
- These fractures can create pathways for mineral-rich fluids to flow and deposit minerals.
Beds:
- Beds refer to layers or strata of rock.
- Minerals can be present within these layers, either as primary minerals that formed during the rock's formation or as secondary minerals that have been deposited later.
Based on the given options, minerals can occur in cracks and crevices (i and ii) as well as in faults or joints (iii). Therefore, the correct answer is option B: Only (i), (ii), and (iii).
Test: Minerals & Energy Resources - 3 - Question 8

Where do minerals occur in igneous rocks?

Detailed Solution for Test: Minerals & Energy Resources - 3 - Question 8
Where do minerals occur in igneous rocks?
In igneous rocks, minerals occur in cracks. Here is a detailed explanation of where minerals occur in igneous rocks:
1. Introduction to igneous rocks:
- Igneous rocks are formed from the solidification of molten rock material.
- The molten rock material, known as magma, cools and solidifies to form igneous rocks.
2. Minerals in igneous rocks:
- Minerals are naturally occurring, inorganic solid substances with a specific chemical composition and crystal structure.
- Igneous rocks are composed of minerals that crystallize from the magma as it cools and solidifies.
3. Cooling and mineral formation:
- As magma cools, it undergoes a process called crystallization, where minerals start to form.
- The minerals in igneous rocks are formed through the crystallization of the various elements present in the magma.
- The specific minerals that form depend on the chemical composition of the magma.
4. Cracks and mineral occurrence:
- During the cooling and solidification of magma, cracks or fractures can develop in the rock.
- These cracks provide pathways for mineral-rich fluids to flow through the rock.
- As the fluids circulate through the cracks, they can deposit minerals, forming veins or mineral-filled fractures within the igneous rock.
5. Benefits of mineral occurrence in cracks:
- The presence of minerals in cracks can contribute to the economic value of igneous rocks.
- Some minerals, such as gold, silver, and copper, are often found in veins or mineral-filled fractures within igneous rocks.
- These mineral occurrences can be important for mining and extracting valuable resources.
In conclusion, minerals in igneous rocks occur in cracks or fractures formed during the cooling and solidification of magma. These mineral occurrences can have economic significance and are often targeted for mining purposes.

Test: Minerals & Energy Resources - 3 - Question 12

Where do minerals occur in sedimentary rocks?

Detailed Solution for Test: Minerals & Energy Resources - 3 - Question 12
Where do minerals occur in sedimentary rocks?
Minerals can occur in sedimentary rocks in various locations within the rock structure. The most common location is in the beds or layers of the sedimentary rock. Here are the detailed explanations:
Beds or layers:
- Sedimentary rocks are formed by the accumulation and cementation of sediment layers over time. Minerals can become trapped within these layers during the sedimentation process.
- As sediment is deposited and compacted, minerals may settle and become cemented together, forming the solid rock structure.
- The minerals can vary in composition and size, depending on the specific type of sedimentary rock and the environment in which it was formed.
Other possible locations where minerals may occur in sedimentary rocks include:
Cracks:
- Sedimentary rocks can have cracks or fractures that form after their initial formation.
- Minerals can precipitate or fill these cracks, creating veins or mineral-filled fractures within the rock.
Crevices:
- Similar to cracks, crevices or fissures in sedimentary rocks can provide spaces for minerals to accumulate.
- These crevices may be formed by various geological processes, such as tectonic activity or weathering.
Faults:
- Faults are fractures or breaks in the Earth's crust where rocks on either side have moved relative to each other.
- Minerals can be deposited along fault lines, forming mineral veins that cut across the sedimentary rock layers.
In summary, minerals in sedimentary rocks primarily occur in the beds or layers of the rock. However, they can also be found in cracks, crevices, and faults within the rock structure. These minerals provide valuable information about the geological history and processes that have occurred in the formation of sedimentary rocks.
Test: Minerals & Energy Resources - 3 - Question 13

In which kind of rocks are the minerals deposited and accumulated in the strata?

Detailed Solution for Test: Minerals & Energy Resources - 3 - Question 13
Answer:
The minerals are deposited and accumulated in the strata of sedimentary rocks. Here is a detailed explanation:
Sedimentary Rocks:
- Sedimentary rocks are formed by the deposition and accumulation of sediments (such as sand, mud, and organic materials) over time.
- These sediments are derived from the weathering and erosion of pre-existing rocks and are transported by water, wind, or ice to a new location where they settle and accumulate.
- As the sediments accumulate, they undergo compaction and cementation, which turns them into solid rock.
- The minerals within the sediments become part of the rock's composition and are preserved within the layers or strata of the sedimentary rock.
Importance of Sedimentary Rocks:
- Sedimentary rocks contain valuable resources such as coal, oil, and natural gas, which are formed from the accumulation and transformation of organic matter.
- They also provide important clues about Earth's history, as the layers of sedimentary rocks can record information about past environments, climate, and the evolution of life.
In conclusion, minerals are deposited and accumulated in the strata of sedimentary rocks.

- Anthracite: Anthracite is the highest quality hard coal. It has a high carbon content, low moisture content, and high energy density. It is a rare and valuable coal type known for its high heating value and clean-burning properties.
- Bauxite: Bauxite is not a type of coal. It is a sedimentary rock that is the primary source of aluminum.
Comparison of Coal Types:
- Lignite is the lowest quality coal with the lowest energy content.
- Bituminous coal is of medium quality, widely used for electricity generation.
- Anthracite is the highest quality hard coal, known for its high carbon content and clean-burning properties.
- Bauxite is not a type of coal but a rock used for aluminum production.
Conclusion:
The highest quality hard coal among the given options is Anthracite. It is a rare and valuable coal type with high carbon content and clean-burning properties.
