HOTS Questions Contemporary India II Chapter 5 Minerals and Energy Resources Class 10 Social Science with Answers

Summary :

I. Mode of occurrence of Mineral :
Where are these minerals found.
Minerals are usually found in “Ores”. The term ore is described as accumulation of any mineral mixed with other elements, it should have sufficient concentration to make its extraction viable. The type of formation or structure in which they are found determines their relative ease of mining and cost of extraction.
 
Minerals Generally Occur in These forms :
(i) In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called vein and the larger are called lodes. They are formed when minerals in liquid / molten & gaseous forms are forced upwards through cavities towards earth’s surface. They cool and solidify as they rise. They include tin, copper, Zinc, lead etc.
 
(ii) Sedimentary Rocks : No. of minerals occur in beds and layers. They have been formed as a result of deposition, accumulation and concentration. of horizontal strata eg Gypsum, potash salt & sodium salt. They are formed as a result of evaporation in arid region.
 
(iii) Decomposition of Surface Rocks : Involves the removal of soluble constituents, leaving a residual mass of weathered material containing ores eg. Bauxite.
 
(iv) Alluvial Deposits : Occur in sands of valley floors and the base of hills. These are called ‘Placer deposits ‘ and are not corroded by water eg gold,silver, tin platinum.
 
(v) Ocean waters contain vast quantities of minerals but most of these are too  widely diffused to be of economic significance, however common salt, magnesium & bromine are largely derived.
 
II. Major Iron Ore Belts in India :
1. Orissa Jharkand Belt : In Orissa high grade hematite ore is found in Badampahar mines in the Mayurbhanj and Kendujhar. In Jharkand haematite iron ore is mined in Gua and Noamundi.
 
2. Durg - Bastar - Chandrapur belt : Lies in chattisgarh and Maharashtra high grade hematitis are found in Bailadila range of hills in Chatisgarh.
 
3. Bellavy Chitradurga - Chikmaglur - Tumkur Belt : In Karnataka has large reserves of iron ore. Kudermuch mines located in western Ghats of Karnataka and known to be one of the largest.
 
4. Maharashtra- Goa Belt : Includes state of Goa and Ratnagir district of Maharashtra. Although ores are not of very high quality yet they are efficiently exploited.
 
III. Conservation of Energy Resources :
Energy is a basic requirement for economic development. Every sector of national economy agriculture, industry, transport, commercial and domestic needs inputs of energy. There is an urgent need to develop a sustainable path of energy development. India is presently one of the least energy efficient countries in the world. We have to adopt a caution approach for judicious use.
- Using public transport instead of individual.
Switching of electricity when not in use.
- Using power saving devices.
- Using non conventional sources of power.

Read the extract and answer the questions that follows :

In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called veins and the larger are 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. They cool and solidify as they rise. Major metallic minerals like tin, copper, zinc and lead etc. are obtained from veins and lodes. In sedimentary rocks a number of minerals occur in beds or layers. They have been formed as a result of deposition, accumulation and concentration in horizontal strata. Coal and some forms of iron ore have been concentrated as result of long periods under great heat and pressure. Another group of sedimentary minerals include gypsum, potash salt and sodium salt. These are formed as a result of evaporation especially in arid regions. Another mode of formation involves the decomposition of surface rocks and the removal of soluble constituents, leaving a residual mass of weathered material containing ores. Bauxite is formed this way. Certain minerals may occur as alluvial deposits in sands of valley floors and the base of hills. These deposits are called ‘placer deposits' and generally contain minerals, which are not corroded by water. Gold, silver, tin and platinum are mosay.

Question : In which rocks the lodes and veins occur ?

Source/Extract Based Questions

We all appreciate the strong dependence of industry and agriculture upon mineral deposits and the substances manufactured from them. The total volume of workable mineral deposits is an insignificant fraction i.e. one per cent of the earth’s crust. We are rapidly consuming mineral resources that required millions of years to be created and concentrated. The geological processes of mineral formation are so slow that the rates of replenishment are infinitely small in comparison to the present rates of consumption. Mineral resources are, therefore, finite and nonrenewable. Rich mineral deposits are our country’s extremely valuable but short-lived possessions. Continued extraction of ores leads to increasing costs as mineral extraction comes from greater depths along with decrease in quality.

Question : What is tidal energy? Name a region of India which provides ideal conditions for utilising tidal energy. 
Answer : 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 pipe that carries it through a power generating turbine. In India, the Gulf of Kuchchh, provides ideal conditions for utilising tidal energy. A 900 mw tidal energy power plant is set up here by the National Hydropower Corporation.
 
Question : 'Energy saved is energy produced.' Assess the statement.
Answer :  Energy is required for all activities in industries, agriculture, transport and domestic use. It implies that all these activities can take initiatives to conserve energy if we discipline ourselves. To begin with, each one of us should be always ready and be vigilant to take note of wasteful use and correct it immediately. It may be as simple as putting off an electrical appliance when not in use. We should develop a mindset to use public transport system instead of individual vehicles. Electronic devices must be switched off when not in use. We should use more and more power saving devices and at home we should plan to install solar panels to generate some electricity. When we do not use a particular quantity of electric power someone else use can it. In absolute sense power plants will need to produce that much less of power; which benefits the environment as that much less fossil fuel will have to be burnt.

Question : What is geothermal energy? Write in detail about it.
Answer : Geothermal energy refers to the heat and electricity produced by using the heat from the interiors of the Earth.
Geothermal energy exists because the Earth grows progressively hotter with increasing depth. Where the geothermal gradient is high, high temperatures are found at shallow depths. Ground water in such areas absorbs heat from the rocks and becomes hot. It is so hot that when it rises to the earth’s surface, it turns into steam. This steam is used to drive turbines and generate electricity. There are several hundred hot springs in India which could be used to generate electricity. Two experimental projects have been set up in India to harness geothermal energy. One is located in the Parvati valley near Manikarn in Himachal Pradesh and the other is located in the Puga Valley, Ladakh.
