Find out are driven by an engine which needs energy where these minerals are found? Can you list a number of items used in your house made of metals. Where do All living things need minerals these metals come from? Various metals are extracted from these about 0. Almost everything we use, from a tiny pin utilise the other Cars, buses, ncert class 10th geography chapter 5 university, aeroplanes are What is a mineral?
In all with a definable internal structure. Why are they so varied? The type of formation or substances called minerals. Some rocks, for structure in which they are found determines instance limestone, consist of a single mineral the relative ease with which mineral ores may only, but majority of the rock consist of several be mined. This also determines the cost of minerals in varying proportions.
Although, extraction. It is, therefore, important for us over minerals have been identified, only to understand the main types of formations a few are abundantly found in most of the in which minerals occur.
Minerals generally occur in these forms: A particular mineral that will be formed i In igneous and metamorphic rocks from a certain combination of elements minerals may occur in the cracks, depends upon the physical and chemical crevices, faults or joints.
The smaller conditions under which the material forms. Geologists use molten and gaseous forms are forced these properties to classify the minerals. They cool and solidify as Study of Minerals by Geographers they rise. Major metallic minerals like tin, and Geologists copper, zinc and lead. The chaptr of mineral occur in beds or layers. They have been resources and associated economic activities formed as a result of deposition, clase of interest to geographers.
A geologist, accumulation and concentration in however, is interested in the formation of horizontal strata. Coal and some forms of minerals, their age and physical and iron ore have been concentrated as a result chemical composition. Another group of sedimentary However, for general and commercial minerals include gypsum, potash salt and purposes minerals can be classified as.
These are ncett ncert class 10th geography chapter 5 university a result of evaporation especially in arid regions. The removal of soluble constituents, leaving term ore is used to describe an accumulation a residual mass of weathered of any mineral mixed with other elements.
Bauxite is The unoversity content of the ore must be in formed this way. Always remember base of hills. Thus, to important among such minerals. However, common salt, Ferrous Minerals magnesium and bromine are largely derived from ocean waters. The ocean beds, Ferrous minerals account for about three- too, are rich in manganese nodules. They provide a strong base for the development of metallurgical industries.
India exports substantial Rat-Hole Mining. Do you know that most quantities of ferrous minerals after meeting of the minerals in India are nationalised her internal demands.
But in most of the tribal areas Iron ore is the basic mineral and the backbone of ncert class 10th geography chapter 5 university north-east India, minerals are of industrial development. India is endowed owned by individuals or communities.
In with fairly abundant resources of iron ore. Meghalaya, there are large deposits ncert class 10th geography chapter 5 university coal, India is rich in good quality iron ores.
Coal Magnetite is the finest iron ore with a very mining in Jowai and Cherapunjee is done high content of iron up to 70 per cent. Hematite The National Green Tribunal has declared ore is the most important industrial iron ore such activities illegal and recommended in terms of the quantity used, but has a that these should be stopped forthwith.
Dig a little deeper: What is the difference between an open pit mine, a quarry and an underground mine with shafts? India is fortunate to have fairly rich and varied mineral resources. However, these are unevenly distributed. Broadly speaking, peninsular rocks contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals. Sedimentary rocks on the western univesity eastern flanks of the peninsula, in Gujarat and Assam have most of the petroleum deposits.
Rajasthan with the rock systems of the peninsula, has reserves of many non-ferrous minerals. The vast alluvial plains of north India are almost devoid of economic minerals. These variations exist largely because of the differences in the geological structure, processes and time Fig. The ore is transported as Kudre in Kannada means horse.
The slurry through a pipeline to a port near highest peak in the western ghats of Mangaluru. Karnataka resembles the face of a horse. Though, the ores are not of very high ncert class 10th geography chapter 5 university, yet they are ncert class 10th geography chapter 5 university exploited.
Ncert class 10th geography chapter 5 university ore is exported through Marmagao port. Manganese Manganese is mainly used in the manufacturing of steel and ferro-manganese alloy. Nearly 10 kg of manganese is required to manufacture one tonne of steel.
Yeography is also used in manufacturing bleaching powder, insecticides and paints. In the adjoining Singbhum district of Jharkhand haematite iron ore is mined in Gua and Noamundi. Very high grade hematites are found in the famous Fig. The range of hills Dig a little deeper: Superimpose the maps comprise of 14 deposits of super high showing unversity of iron ore, manganese, grade hematite iron ore. It has the best coal and iron and steel industry.
Do you see physical properties needed for steel any correlation. However, these Tu makuru belt in Karnataka has large minerals, which include copper, bauxite, lead, reserves of iron ore. The Kudremukh mines zinc and gold play a vital role in a number of located in the Western Ghats of Karnataka metallurgical, engineering and electrical are a per cent export unit. Kudremukh industries.
Let us study the distribution of deposits are known to be one of the largest geograaphy and bauxite. Being malleable, ductile and a good conductor, copper is mainly used in electrical cables, electronics and chemical.
The Balaghat geogrxphy in Madhya Odisha was the largest bauxite producing Pradesh, Khetri mines in Chaptwr and Class 10th Ncert Geography Chapter 6 Solution University state in India in Panchpatmali Singhbhum district of Jharkhand are leading deposits in Ncert class 10th geography chapter 5 university district are the most producers of copper.
Bauxite Though, several 10t contain aluminium, it is from bauxite, a clay-like substance that alumina and later aluminium is obtained. Bauxite deposits are formed by the decomposition of a wide variety of rocks rich in aluminium silicates.
Aluminium is an important metal because it combines the strength of metals such as iron, with extreme lightness and also with good conductivity and great malleability. Bauxite on the physical map of India. A fter the discovery of aluminium Rock Minerals Emperor Napoleon III wore buttons and hooks on his clothes made of aluminium Limestone is found in association with rocks and served food to his more illustrious composed of calcium carbonates or calcium guests in aluminium utensils and the and magnesium carbonates.
It is found in less honourable ones were served ncert class 10th geography chapter 5 university gold sedimentary rocks of most geological and silver utensils. Thirty years after this formations. Limestone is the basic raw incident aluminium bowls ncet most material for the cement industry and essential common with the beggars in Paris. Mica is a mineral made up of a universty of plates or leaves.
It splits easily into thin sheets. These sheets can be so thin that a thousand can be layered into a mica sheet of a few centimeters high. Mica can be clear, black, green, red yellow or brown. Due to its excellent di-electric strength, low power loss factor, insulating properties and resistance to high voltage, mica is one of the most indispensable minerals used in electric and electronic industries.
Mica deposits are found in the northern edge of the Chota Nagpur plateau. Koderma Gaya � Hazaribagh belt of Jharkhand is the leading producer.
In Rajasthan, the major mica producing Fig. Nellore mica belt of state-wise share in per cent, � Hazards of Mining Have you ever wondered about the efforts the miners make in making life comfortable for you? What are the impacts of mining on the health of the miners and the environment?
The dust and noxious fumes inhaled by miners make them vulnerable to pulmonary diseases. The risk of collapsing mine roofs, inundation and fires in coalmines are a constant threat to miners. The water sources in the region get contaminated due to mining. Dumping universiyy waste and slurry leads to degradation of land, soil, Fig.
