(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.

(i) Ferrous metallic mineral: The metallic minerals that contain iron are known as ferrous minerals. Its common examples include iron ore, manganese, chromite and nickel.
(ii) Non-metallic minerals: As the name suggests, non-metallic minerals are the minerals that do not contain metals, e.g. limestone, mica, coal, gypsum, dolomite, phosphate, salt, manganese, granite etc. They are the minerals that do not contain metallic elements. They are generally hard and have a shiny surface.

Correct Answer: B
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.

MULTIPLE CHOICE QUESTION
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.
A
Solar Energy
B
Tidal Energy
C
Biogas
D
Geothermal Energy
Correct Answer: C
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.

Try yourself: Find the incorrect option:
A
India is presently one of the least energy efficient countries in the world.
B
We have to adopt a cautious approach for the judicious use of our limited energy resources.
C
For example, as concerned citizens we can do our bit by using public transport systems instead of individual vehicles; switching off electricity when not in use, using power - saving devices and using non-conventional sources of energy.
D
After all, "energy spent is energy consumed."
Correct Answer: D
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.
