Minerals are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Answer: In igneous and metamorphic rocks, minerals occur in the cracks, crevices, faults or joints. The Class 10th Geography Chapter 5 Ncert Solutions China smaller occurrences are called veins and the larger are called lodes. Metallic minerals like tin, copper, zinc and lead etc. Answer the following questions in about words. Answer: In India, coal occurs in rock series of two main geological areas, namely Gondwana, a little over million years in age and in tertiary deposits Class 10th Geography Chapter 5 Ncert Solutions China Class 10th Geography Chapter 5 Ncert Solutions China which are only about 55 million years old.
Answer: India being a tropical country has great possibilities of tapping Class 10th Geography Chapter 5 Ncert Solutions China Class 10th Geography Chapter 5 Ncert Solutions China solar energy. Photovoltaic technology converts sunlight directly into electricity. Solar energy is becoming popular in rural and remote Class 10th Geography Chapter 5 Ncert Solutions China Class 10th Geography Chapter 5 Ncert Solutions China areas of India fastly. Koderma Gaya � Hazaribagh belt of Jharkhand is the leading producer. In Rajasthan, the major mica producing area is around Ajmer. Nellore mica belt of Andhra Pradesh is also an important producer Class 10th Geography Chapter 5 Ncert Solutions China in the country.
Limestone is found in association with rocks composed of calcium carbonates or calcium and magnesium carbonates. It Class 10th Geography Chapter 5 Ncert Solutions China is found in sedimentary rocks of most geological formations.
Limestone is the basic raw material for the cement industry and essential for smelting iron ore in the blast furnace. 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. 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 non-renewable. Continued extraction of ores leads to increasing costs as mineral extraction comes from greater depths along with decrease in quality. Energy can be generated from fuel minerals like coal, petroleum, natural gas, uranium and from electricity. Energy resources can be classified as conventional and non-conventional sources. Conventional sources include: firewood, cattle dung cake, coal, petroleum, natural gas and electricity both hydel and thermal.
Non-conventional sources include solar, wind, tidal, geothermal, biogas and atomic energy. Firewood and cattle dung cake are most common in rural India. According to one estimate more than 70 per cent energy requirement in rural households is met by these two; continuation of these is increasingly becoming difficult due to decreasing forest area. Moreover, using dung cake too is being discouraged because it consumes most valuable manure which could be used in agriculture.
Coal: In India, coal is the most abundantly available fossil fuel. It is used for power generation, to supply energy to industry as well as for domestic needs.
Coal, therefore, is found in a variety of forms depending on the degrees of compression and the depth and time of burial. Decaying plants in swamps produce peat. Which has a low carbon and high moisture Class 10th Geography Chapter 5 Ncert Solutions China contents and low heating capacity. Lignite is a low grade brown coal, which is soft with high moisture content. The Class 10th Geography Chapter 5 Ncert Solutions China principal lignite reserves are in Neyveli in Tamil Nadu and are used for generation of electricity. Coal that has been buried deep and subjected to increased temperatures is bituminous coal.
It is the most popular coal in commercial use. Metallurgical coal is high grade bituminous coal which has a special value for smelting Class 10th Geography Chapter 5 Ncert Solutions China iron in blast furnaces. Anthracite is the highest quality hard coal. Most of the petroleum occurrences in India are Class 10th Geography Chapter 5 Ncert Solutions China associated with anticlines and fault traps in the rock formations of the tertiary age.
In regions of folding, anticlines or domes, it occurs where oil is trapped in the crest of the uphold. The oil bearing Class 10th Geography Chapter 5 Ncert Solutions China layer is a porous limestone or sandstone through which oil may flow.
The oil is prevented from rising Class 10th Geography Chapter 5 Ncert Solutions China or sinking by intervening non-porous layers. Petroleum is also found in fault traps between porous and non-porous rocks. Gas, being lighter usually occurs above the oil.
Mumbai High, Gujarat and Assam are major petroleum production areas in Class 10th Geography Chapter 5 Ncert Solutions China India. From the map locate the 3 major off shore fields of western India. Ankeleshwar is the most important field of Gujarat. Assam is the oldest oil producing state of India. Digboi, Naharkatiya and Moran-Hugrijan are the important oil fields in the state.
Natural gas is an important clean energy resource found in association Class 10th Geography Chapter 5 Ncert Solutions China with or without petroleum. It is used as a source of energy as well as an industrial raw material Class 10th Geography Chapter 5 Ncert Solutions China Class 10th Geography Chapter 5 Ncert Solutions China in the petrochemical industry. Natural gas is considered an environment friendly fuel because of low carbon dioxide emissions and is, therefore, the fuel for the present century.
The km long Hazira-Vijaipur- Jagdishpur cross country gas pipeline Class 10th Geography Chapter 5 Ncert Solutions China links Mumbai High and Bassien with the fertilizer, power and industrial complexes in western and northern India. The power and fertilizer industries are the key users of natural gas. Electricity is generated mainly in two ways: by Class 10th Geography Chapter 5 Ncert Solutions China running water which drives hydro turbines to generate hydroelectricity; and by burning other fuels such as coal, petroleum and natural gas to drive turbines to produce thermal power.
Once generated the electricity is exactly the same. The growing consumption of energy has resulted in the country becoming increasingly dependent on fossil fuels such as Class 10th Geography Chapter 5 Ncert Solutions China coal, oil and gas. Rising prices of oil and gas and their potential shortages have raised uncertainties about the security of energy supply in future, which in turn has serious repercussions on the growth of the national economy.
Moreover, increasing use of fossil fuels also causes serious environmental problems. Hence, there is a pressing need Class 10th Geography Chapter 5 Ncert Solutions China to use renewable energy sources like solar energy, wind, tide, biomass and energy from waste material.
These are called non- conventional energy sources. Thermal electricity is generated by using coal, petroleum and natural gas. The thermal power stations use non-renewable fossil fuels for generating electricity. Hydro electricity is generated by fast flowing water, which is a renewable resource.
It is obtained by altering the structure of atoms. When such an alteration is made, much energy is released in the form of heat and this is used to generate electric power. Uranium and Thorium, which are available in Jharkhand and the Aravalli ranges of Rajasthan are used for generating atomic or nuclear power.
The Monazite sands of Kerala is also rich in Thorium. India is a tropical country. It Class 10th Geography Chapter 5 Ncert Solutions China has enormous possibilities of tapping solar energy. Photovoltaic technology converts sunlight directly into electricity. Solar energy is fast becoming popular in rural and remote areas. Some big solar power plants are being established in different parts Class 10th Geography Chapter 5 Ncert Solutions China of India which will minimize the dependence of rural households on firewood and dung cakes, which in turn will contribute to environmental conservation and adequate supply of manure in agriculture.
India has great potential of wind power.
