Mineral Wealth Of IndiaA mineral is a natural substance of organic or inorganic origin with defined physical and chemical properties. Minerals are unevenly distributed on Earth. Good quality minerals are available less in quantity and are also non-renewable resources, which once exhausted, can’t be replaced immediately. Minerals are of two basic types metallic and non-metallic. Metallic minerals, like iron, nickel, manganese, tungsten etc., are ferrous, since they have iron content. Some non-ferrous metallic minerals are gold, silver, copper, tin etc.Long and Short Essays on Mineral Wealth Of India for Kids and Students in EnglishGiven below are two essays in English for students and children about the topic of ‘Mineral Wealth Of India’ in bot h long and short form. The first essay is a long essay on Mineral Wealth Of India of 400-500 words. This long essay about Mineral Wealth Of India is suitable for students of class 7, 8, 9 and 10, and also for competitive exam aspirants. The second essay is a short essay on Mineral Wealth Of India of 150-200 words. These are suitable for students and children in class 6 and below.Long Essay on Mineral Wealth Of India 600 Words in EnglishBelow we have given a long essay on Mineral Wealth Of India of 500 words is helpful for classes 7, 8, 9 and 10 and Competitive Exam Aspirants. This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.The non-metallic minerals may or may not contain organic matter. Coal and petroleum are organic in nature, while mica, limestone, graphite and gypsum are inorganic. Minerals such as coal and iron are of industrialimportance; mica, manganese, copper, lead and zinc are of economic importance; and coal, petroleum, thorium and uranium are of national importance.India is the leading producer of some of the minerals and contains a diverse and significant store of these minerals. Of the 89 minerals produced in the country, 4 are fuel minerals, 11 metallic, 52 non-metallic and 22 minor minerals. India is the largest producer of mica blocks and mica splittings; ranks second in the production of chromite, baryte, talc and steatite; ranks third in the production of coal, lignite, and bauxite; fourthin iron ore, fifth in steel, seventh in zinc, eighth in copper, tenth in aluminium and eleventh in mica.Iron ore, copper ore, chromite ore, zinc concentrates, gold, manganese ore, bauxite, lead concentrates and silver account for the entire metallic production. Limestone, magnesite, dolomite, baryte, kaolin, gypsum, apatite, steatite and fluorite account for 92% of non-metallic minerals.India has a large number of economically useful minerals and they constitute one-quarter of the world’s mineral resources. About two-thirds of its iron deposits lie in a belt along Odisha andJharkhand border. Other haematite deposits are found in Madhya Pradesh, Karnataka, Maharashtra and Goa. Magnetite iron ore is found in Tamil Nadu, Jharkhand and Himachal. Bituminous coal is found in Jharia and Bokaro in Jharkhand and Ranigunj in West Bengal.Lignite coals are found in Neyveli in Tamil Nadu. Next to Russia, India has the largest supply of manganese. The manganese mining areas are Madhya Pradesh, Maharashtra and Jharkhand-Odisha area. Chromite deposits are found in Jharkhand, Cuttack district in Odisha, Krishna district in Andhra Pradesh and Mysore andHassan in Karnataka. Bauxite deposits are found in Jharkhand, South-West Kashmir, Central Tamil Nadu, and parts of Kerala, Uttar Pradesh, Maharashtra and Karnataka.Belts of high quality mica are Bihar, Andhra Pradesh and Rajasthan. Gypsum reserves are in Tamil Nadu and Rajasthan. Nickel ore is found in Cuttack and Mayurbhanj in Odisha. Copper ore bearing areas are Agnigundala in Andhra Pradesh, Singhbhum in Jharkhand, Khetri and Dartiba in Rajasthan, and parts of Sikkim and Karnataka.The Ramagiri fields in Andhra Pradesh, Kolar and Hutti in Karnataka are important gold mines. The Panna diamond belt is the only diamond producing area in the country, which covers the districts of Panna, Chhatarpur and Satna in Madhya Pradesh, as well as some parts of Banda in Uttar Pradesh. Petroleum deposits are found in Assam and Gujarat. Fresh reserves were located off Mumbai Coast. The potential oil bearing areas are Assam, Tripura, Manipur, West Bengal, Punjab, Himachal, Kachchh and the Andamans. India also possesses the all-too-valuable nuclear Uranium as well as some varieties of rare Earths.The mineral wealth of India at present comprises an adequate range of useful products that are necessary for the industrial development of the country. An appraisal of the reserves shows that while in respect of minerals essential for basic industries coal and iron the reserves are ample, the country is deficient in a fairly long list of vital minerals like ores of copper, tin, lead, zinc, nickel, cobalt and in sulphur and most important of all, petroleum.The position with regard to aluminium ore, refractories, abrasives, limestone etc., may be considered as fairly adequate while in respect oftitanium and thorium ores and of mica, the country has considerable reserves.Until recently, mineral exploration and their utilisation in the country received little attention. Except for coal, iron ore and petroleum required for internal use, the majority of minerals were extracted in India for the purpose of bulk export without any processing and fabrication. These exports brought but a small return to the country.Nearly a hundred minerals are known to be produced or mined in India, of which nearly 30 may be considered more important and the restseem to be capable of material development in future with the expansion of industries.It should be made clear at the outset that though progress has been made in the survey of mineralised areas in recent years and the principal mineral regions have been ascertained, exploration of mineral resources has not been thorough or complete in most cases and present estimates are just rough guesses. The power resources in India comprise coal, oil and hydroelectricity. India’s coal mining is centered mainly in Bihar and West Bengal. The total workable reserves of coal down to a depth of1000 ft are estimated at 20000 million tonnes, of which the good quality coal would amount to 5000 million tonnes. The reserves of coking coal, however, are small, amounting to only 2000 million tonnes. As against relatively meagre resources of coal and oil, the hydroelectric resources of India are considerable with estimates varying from about 30 to 40 million horse-power. India possesses large quantities of high grade iron ore and may be classified as one of the countries which can reasonably expect a long continued development of heavy industry; though, in proportion to the population, thesereserves are lower than the main ore regions of the world.Incessant mining and plundering of mineral resources has disastrous effects on the ecosystem of a region. Water scarcity has increased, river beds are getting damaged and even the biodiversity is getting hampered.Short Essay on Mineral Wealth Of India 300 Words in EnglishBelow we have given a short essay on Mineral Wealth Of India is for Classes 1, 2, 3, 4, 5, and 6.This short essay on the topic is suitable for students of class 6 and below.In India, over the years, a national mineral policy has evolved. The policy addresses certain new aspects and elements like mineral exploration in the sea-bed, development of proper inventory, proper linkage between exploitation of minerals and development of mineral industry, protection of forests, environment and ecology from the adverse effects of mining, enforcement of mining plan for adoption of proper mining methods, optimum utilisation of minerals, export of minerals invalue-added form and recycling of metallic scrap and mineral waste.The Mines and Minerals (Regulation and Development) Act, 1957 lays down the legal framework for the regulation of mines and development of all minerals other than petroleum and natural gas. The Central Government has framed the Mineral Concession Rules 1960, for regulating grant of prospecting licenses and mining leases in respect of all minerals other than atomic minerals and minor minerals. The State Governments have framed the rules in regard to minor minerals.The Central Government has also framed the Mineral Conservation and Development Rules, 1988 for conservation and systematic development of minerals. These are applicable to all minerals except coal, atomic minerals and minor minerals. New regulations from 2012 onwards have stated that any mining activity would, at first, require clearance or permission from the Ministry of Environment and Forests.Thus, our policymakers should ensure that they create no more ‘ecological refugees’, people who are rendered homeless due to mindless mining in their dwelling places. Only then canminerals provide rich returns to the economy and strengthen it.Mineral Wealth Of India Essay Word Meanings for Simple UnderstandingOrganic –pertaining to a class of chemical compounds that formerly comprised only those existing in or derived from plants and animalsAdequate – barely sufficient or suitableAppraisal – an estimate or considered opinion of the nature, quality, importance, etcFabrication –the act or process of fabricating, manufactureBiodiversity –the diversity (number and variety of species) of plant and animal life within a regionAscertain – to find out definitelyIncessant –continuing without interruption, ceaseless。

但是，美国小规模水电的发展面临资金和法规限制，以及环境和社区影响等挑战。
为了克服这些障碍，政府和私人部门可以采取措施，如提供财政支持、简化审批程序、加强社区参与等。
通过这些努力，小规模水电有望成为美国未来可再生能源发展的重要组成部分。
在2004年，XXX（USDOE）对美国的每个试验段作为水电开发潜力的网站进行了分析。
该数据库确定了近50个可行的小型水电站地点，能够提供超过10万兆瓦的电力，这相当于美国当前电力发电量的约10％，但却供应了80％的电力发电量（EIA，2009年）。
虽然这个数量显然不足以消除美国对化石燃料的依赖，但它已经不能满足大部分RPS超过2020年的要求。
西北太平洋的各个州，包括加利福尼亚、华盛顿、爱达荷州和俄勒冈州，拥有大部分潜在的小型水电站，但没有一个单一的国家可以独立开发这些水电站。
此外，水电不像大多数其他可再生能源那样已经成熟，因为许多小型水电站已经存在，这些站点由竞争生产公司生产涡轮机和其他设备，并且这些设备非常可靠，可以使用几十年。
例如，XXX（2006）指出，与硅太阳能生产所需的原材料相比，小型水电站的开发更加便利和可行，这暗示着输入价格可能会下降。
这篇文章的主要目的是确定开发这些小型有效水电站的成本效益。
Water Resources In India>Water Resources In India Essay:Water is the most important and valuable natural resource on Earth. It sustains all life and life itself originated in water. Before the discovery of traces of water on Mars, Earth was the only planet in the solar system to contain water. About 71% of Earth’s surface is covered with water, but only 3% of the available water is freshwater. About two-thirds of the freshwater lies frozen in the form of glaciers and ice caps. The rest of the small portion is available in the form of groundwater and surface water.Long and Short Essays on Water Resources In India for Kids and Students in EnglishGiven below are two essays in English for students and children about the topic of ‘Water Resources In Indi a’ in both long and short form.

This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.Water is used in the agriculture for irrigation of crops. In industries, water is used as a coolant, solvent and in manufacturing processes. Hydroelectricity is electricity generated with the help of water. Water is also used for navigationand transport of goods. India covers 2.45% of the world area an d possesses 4% of world’s water resources. Precipitation contributes about 4000 cu km of water to the country. India has a large number of surface water resources, in the form of rivers, lakes, ponds, tanks and other small bodies. The three main rivers of North India are Indus, Ganga and Brahmaputra, which carry 60% of the total surface water in India. The flow of India’s rivers constitutes 6% of discharge of all the rivers of the world.Being an agriculture-centric country, India has developed a number of irrigation schemes.Jrrigation projects of Bhakra-Nangal, Hirakud, Damodar Valley, Nagarjuna Sagar and Indira Gandhi Canal have featured prominently in Five Year Plan.The land area between Punjab and Brahmaputra Valley has abundant groundwater resources. The technology for identification of more aquifers can be developed further, as has been done in Punjab, Haryana, Western Uttar Pradesh, Rajasthan, Gujarat and Tamil Nadu. India also has more than 600 km long coastline. Lagoons exist in the states of Kerala, Odisha and West Bengal, where the coastline isindented. This water, known as brackish water, is used for the cultivation of paddy, coconut etc., and for fishing.Unmindful use of groundwater has led to the lowering of the water table. Excessive quantity of water used in irrigation increases soil salinity, affecting the crops. Disputes also have arisen where water bodies are shared between two states and distribution of water is in question. For example, in the absence of Cauvery Agreement, Karnataka developed some irrigation schemes, which affected Tamil Nadu’s rice delta.“Water, water, everywhere, not a drop to drink.” The Rime of the Ancient Mariner -By ST ColeridgeHydroelectricity can solve a part of India’s energy crisis, triggered by hike in oil prices. It is generated by the use of gravitational force of falling or flowing water. It is the most widely used form of renewable energy, with production in 150 countries. India has one of the greatest hydroelectric power potentials in the world. Bhakra Beas Management Board (BBMB) has installed a hydel power grid in North India. Hydroelectricity is cost-effective. Once ahydroelectric complex is constructed, no waste is produced and carbon-dioxide emission is also less as compared to fossil fuel powered plants.Water of the rivers and other natural sources is getting polluted due to industrial chemicals, pesticides, oil slicks and household wastes. Around 75% of surface water in India is polluted. Rajasthan and Maharashtra have high fluoride content in water, while arsenic has been found in water of West Bengal and Bihar. There are 14 river basins found to be most affected by dumping of sewage. For example, leather factories in Kanpur pump around 5.8 litre ofwaste water into Ganga everyday. Yamuna is also known as ‘Open Drain’.Short Essay on Water Resources In India 200 Words in EnglishBelow we have given a short essay on Water Resources In India is for Classes 1, 2, 3, 4, 5, and 6. This short essay on the topic is suitable for students of class 6 and below.The Central Pollution Control Board (CPCB) along with the State Boards monitor water quality at 507 stations. Some of the legislations passed by government include water(Prevention and Control of Pollution) Act, 1974, Water Cess Act, 1977, Environment Protection Act, 1986 and National Water Policy, 2002. Ganga Manthan dialogue was initiated recently, to discuss measures to check pollution of Ganga water. Placing portable toilets and small scale water treatment plants along the river can go a long way in halting pollution.Other than these, efforts of NGOs and citizens have also counted in the cleaning of lakes such as Puttenahalli lake, Dal lake, Agara lake, Rankala lake etc. Maintenance of water quality and water conservation are the needs of thehour. Villages’can collaborate to form watersheds, so that wells and other water reservoirs can be recharged with water. Ralegan Siddhi is a village in Maharashtra which successfully implemented this approach. Rainwater harvesting has been made mandatory in Tamil Nadu.India’s water resources are in ample amount, but what is available freely, shouldn’t be wasted. Let us be more responsible and emulate successful models like that of Ralegan Siddhi in every part of India.Water Resources In India Essay Word Meanings for Simple UnderstandingCoolant –a substance, usually a liquid or gas, used to reduce the temperature of a system below a specified value by conducting away the heat produced in the operation of the systemSolvent – a substance that dissolves another to form a solutionLagoon –an area of shallow water separated from the sea by low sandy dunesCoastline –the outline or contour of a coast, shorelineIndented – to form deep recesses inSalinity –containing, or resembling common table salt, salty or saltlikeEenewable energy –any naturally occurring, theoretically inexhaustible source of energy, as biomass, solar, wind, tidal, wave, and hydroelectric power, that is not derived from fossil or nuclear fuelAluoride –a salt of hydrofluoric acid consisting of two elements, one of which is fluorine, as sodium fluoride, NaFArsemc – a grayish white element having a metallic luster, vaporising when heated, and forming poisonous compoundsWatershed –the dividing line between two adjacent river systems, such as a ridge。
