Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Match the following items given in column A with those in column B:
Explanation
(i) Iron ore:The primary use of iron ore (98%) is to make steel. The remaining 2% is used in various other applications, such as: powdered iron, for certain types of steels, magnets, auto parts and catalysts. radioactive iron (iron 59), for medicine and as a tracer element in biochemical and metallurgical research.
(ii) Copper: Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat.
(iii) Manganese: Most of the manganese produced is used in the form of ferromanganese and silico manganese alloys for iron and steel manufacture. Manganese ores containing iron oxides are first reduced in blast furnaces or electric furnaces with carbon to yield ferromanganese, which in turn is used in steelmaking.
(iv) Mica: 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.

Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Arrange the following in correct sequence:
Following is the sequence of generating tidal energy:
(i) During high tide water flows into the inlet and gets trapped when the gate is closed.
(ii) Floodgate dams are built across inlets.
(iii) By this method oceanic tides can be used to generate electricity.
(iv) After the tide falls outside the floodgate, the water retained by the floodgate flows back to the sea via pipe that carries it through a power - generating turbine.
Explanation
Oceanic tides can be used to generate electricity. Floodgate dams are built across inlets. During high tide water flows into the inlet and gets trapped when the gate is closed. After the tide falls outside the flood gate, the water retained by the floodgate flows back to the sea via a pipe that carries it through a power-generating turbine. In India the Gulf of Khambhat, the Gulf of Kachchh in Gujarat on the western coast and Gangetic delta in Sunderban regions of West Bengal provide ideal conditions for utilising tidal energy.

Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Arrange the following in correct sequence:
Following is the sequence of generating geothermal :
(i) It is so hot that when it rises to the earth's surface, it turns into steam.
(ii) Groundwater in such areas (where the geothermal gradient is high) absorbs heat from the rocks and becomes hot.
(iii) This steam is used to drive turbines and generate electricity.
(iv) Geothermal energy exists, because the earth grows progressively hotter with increasing depth.
Explanation
Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, to heat buildings, and to generate electricity.

Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Analyse the information given below, considering one of the following correct options:
Shrubs, farm waste, animal and human waste are used to produce biogas for domestic consumption in rural areas. Decomposition of organic matter yields gas, which has higher thermal efficiency in comparison to kerosene, dung cake and charcoal. Biogas plants are set up at municipal, cooperative and individual levels. The plants, using cattle dung are known as 'Gobar gas plants' in rural India. These provide twin benefits to the farmer in the form of energy and improved quality of manure. Biogas is by far the most efficient use of cattle dung. It improves the quality of manure and also prevents the loss of trees and manure due to burning of fuel wood and cow dung cakes.
Explanation
Biogas is an environmentally-friendly, renewable energy source. It's produced when organic matter, such as food or animal waste, is broken down by microorganisms in the absence of oxygen, in a process called anaerobic digestion.

Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Assertion and Reason Type Questions:
In the questions given below, there are two statements marked as Assertion (A) and Reason (R). Read the statements and choose the correct option:
Assertion (A) : Toothpaste cleans our teeth.Reason (R) : The sparkle in some toothpastes comes from mica.
Explanation
Fluorspar(fluoride), mica (sparkle) and titanium (titanium dioxide) are minerals and materials that all contributes to the process of toothpaste. Powdered mica is used in many cosmetics and in toothpaste to add sparkle. Toothpaste prevent our teeth from decaying.

Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Assertion and Reason Type Questions:
In the questions given below, there are two statements marked as Assertion (A) and Reason (R). Read the statements and choose the correct option:
Assertion (A) : India is fortunate to have fairly rich and varied mineral resources.Reason (R) : These variations exist largely because of the differences in the geological structure, processes and time involved in the formation of minerals.
Explanation
India is fortunate to have fairly rich and varied mineral resources. However, these are unevenly distributed.
(i) Broadly speaking, peninsular rocks contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals.
(ii) Sedimentary rocks on the western and eastern flanks of the peninsula, in Gujarat and Assam have most of the petroleum deposits.
(iii) Rajasthan with the rock systems of the peninsula, has reserves of many non-ferrous minerals.
(iv) The vast alluvial plains of north India are almost devoid of economic minerals.
(v) These variations exist largely because of the differences in the geological structure, processes and time involved in the formation of minerals.

Q9:
Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Find the incorrect option:
Explanation
Electric energy is most often measured either in joules (J), or in watt hours (W·h) representing a constant power over a period of time. During operation, some part of the energy depending on the electrical efficiency is consumed in unintended output, such as waste heat.

Question for Assertion & Reason Type Questions: Minerals and Energy Resources
Try yourself: Direction: In the Following Questions, A Statement of Assertion Is Followed by A Statement of Reason. Mark The Correct Choice As:Assertion : Thermal power stations are located on or near the coalfields.
Reason : Coal is a bulky material, which loses weight on use as it is reduced to ash. Hence, heavy industries and thermal power stations are located on or near the coalfields.
Explanation
Thermal power stations are usually located near a river because they require a vast and continuous supply of water so that water can be converted into steam by burning coal, and the turbine can rotate.
Coal is a bulky material and transportation is difficult and costly. If not transported in a proper way, it may get crushed and reduced to ash. This results in reduction of the weight of coal.
