Test: Mineral & Energy Resources - 4 - Class 10 MCQ

The correct option is D.
 These are the physical properties of the minerals and thus are not concerned with the geography.

The correct option is C.
Rocks like limestone or quartzite are composed primarily of one mineral—calcite or aragonite in the case of limestone, and quartz in the latter case.

D is the correct option.Gold, silver, platinum, and palladium each have an ISO 4217 currency code. The best known “precious metals” are the coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage.

B is the correct option.In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called Veins and the larger is 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.

A is the correct option.Major metallic minerals like tin, copper, zinc and lead etc. are obtained from veins and lodes. sodium salt. These are formed as a result of evaporation especially in arid regions.

A is the correct option.Minerals are found in layers or strata in sedimentary rocks. Minerals are accumulated in horizontal strata after being exposed to high heat and pressure for a long period of time. Coal, iron ore, gypsum, potash salt etc are formed in this way.

Formation of Sedimentary Minerals through Evaporation:
Evaporation is one of the processes that can lead to the formation of sedimentary minerals. When water evaporates, it leaves behind dissolved substances, which can eventually precipitate and form minerals. In arid regions, where evaporation rates are high and water bodies tend to be shallow, the concentration of dissolved minerals increases, leading to the formation of specific minerals.
Identifying the Sedimentary Mineral Formed through Evaporation:
Among the options provided, the sedimentary mineral formed as a result of evaporation, especially in arid regions, is potash salt (option B). Here is a detailed explanation:
- Coal: Coal is a sedimentary rock formed from the remains of plant material, not through evaporation.
- Potash Salt: Potash salt, also known as potassium chloride, is commonly formed through the evaporation of saline water in arid regions. The high concentration of dissolved potassium and chloride ions in the water leads to the precipitation of potash salt.
- Iron Ore: Iron ore is formed through various processes, including sedimentation, and is not specifically associated with evaporation.
- Sulphur: Sulphur can be formed through volcanic activity or as a byproduct of certain chemical reactions, but it is not directly related to evaporation.
Hence, the correct answer is Option B: Potash salt.

D is the correct option.peninsular rocks contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals. Sedimentary rocks on the western and eastern flanks of the peninsula, in Gujarat and Assam have most of the petroleum deposits.

The correct answer is B as The most striking feature of the Indian minerals is their uneven distribution. Some areas are very rich in minerals while some others are completely devoid of this valuable asset.Minerals are rarely found in Northern plains of India.

Magnetite is the finest iron ore with a very high content of iron up to 70 per cent. It has excellent magnetic qualities, especially valuable in the electrical industry. Hematite ore is the most important industrial iron ore in terms of the quantity used, but has a slightly lower iron content than magnetite. (50-60 per cent).

 

B is the correct option.Bauxite is a mineral which is formed by decomposition of rocks, leaving a residual mass of weathered material.

B is the correct option.Bailadila is famous for producing iron which is used for steel making. 'BAILADILA' is a hill range in Chattisgarh which is famous for “the very high grade hematites” which are found in bailadila.

The correct option is Option D.
When iron ore is converted into iron, manganese removes oxygen and sulfur. Also, it is an essential alloy that helps to convert iron into steel. Hence, manganese is an important raw material for the iron and steel industry.
 

Non-ferrous Minerals:
(i) India’s reserves and production of non- ferrous minerals is not very satisfactory. 
(ii) However, these minerals, which include copper, bauxite, lead, zinc and gold play a vital role in a number of metallurgical, engineering and electrical industries.

The  correct answer is C as India is critically deficient in the reserve and production of copper. The Balaghat mines in Madhya Pradesh, Khetri mines in Rajasthan and Singhbhum district of Jharkhand are leading producers of copper.

The correct option is B.
Koderma is the leading producer of Mica. It is located in Hazaribagh belt of Jharkhand.

The correct answer is D as Mica is one of the most indispensable minerals used in electric and electronic industries, due to its Di-electric strength, low power factor, insulating properties and resistance to high voltage

Minerals belong to the category of:

C: Non-renewable and finite
Explanation:

Minerals are naturally occurring substances that are found in the Earth's crust. They are formed over millions of years through geological processes. Here's why minerals are categorized as non-renewable and finite resources:
1. Limited supply: Minerals are present in limited quantities on Earth. Once they are extracted and used, they cannot be replenished within a human lifespan. The rate at which minerals are being consumed is much faster than the rate at which they are formed.
2. Non-renewable: Unlike renewable resources such as solar energy or wind energy, minerals cannot be naturally regenerated or replenished. Once a mineral deposit is depleted, it cannot be replaced by natural processes.
3. Finite availability: The Earth has a finite amount of minerals, and their availability is subject to geological factors. Some minerals, like rare earth elements, are particularly scarce and difficult to find in economically viable quantities.
4. Extraction and environmental impact: The extraction of minerals often involves mining, which can have significant environmental impacts such as habitat destruction, soil erosion, and water pollution. These impacts further contribute to the finite nature of mineral resources.
In conclusion, minerals belong to the category of non-renewable and finite resources due to their limited supply, non-renewable nature, finite availability, and associated environmental impacts.

It include fuels such as firewood, cattle dung and agricultural wastes, which are traditionally gathered, and not bought at a price and used especially in rural households. 

The correct option is B.
Energy generated by using wind, solar, small hydro, tides, geothermal heat and biomass is known as non-conventional energy. All these sources are renewable processes of energy generation and do not cause environmental pollution.
