minerals are non renewable resources. they will get over at a particular period. if we dont conserve it we will be facing many problems. continued extraction of minerals leads to imcreasing cost as minerals cimes from greater depth of the earth along with decreased quality.

Minerals are naturally occurring substances that have a definite chemical composition. Minerals are formed in different types of geological environments, under varying conditions. Minerals can be identified on the basis of their physical properties such as colour, density, hardness and chemical property such as solubility. Minerals are distributed in rocks and sea bed also. Tropical regions are very rich in terms of mineral resources. Types of Minerals: On the basis of composition, minerals are classified into metallic and non-metallic types. Metallic, minerals contain metals in raw form. Metals are hard substances that conduct heat and electricity and have lustre or shine. For example, iron ore and bauxite. Metallic minerals are of two types: (a) Ferrous and (b) Non-ferrous. Ferrous minerals contain iron ore, manganese and chromites. Most of the Iron and steel industries and heavy industries depends on this mineral. Non-ferrous minerals do not contain iron but may contain some other metals like gold, silver, copper or lead. Non-metallic minerals do not contain metals. For example, limestone, mica, gypsum, coal and petroleum. Mining, drilling and quarrying are the three extraction methods of minerals. Mining is the process of taking out minerals from rocks buried under the earth’s surface. The process of mining includes two methods: (a) Open cast mining, (b) Shaft mining Deep wells are bored to take minerals out and this process is called drilling. In the process of quarrying, minerals that lie near the surface are simply dug out. Mineral based industries are the backbone of industrial development of a naion. Mining needs cheep labour and resources to extract it off. Distribution of Minerals: Minerals are found in igneous rock, metamorphic rocks and sedimentary rocks. Iron ore, nickel, copper minerals are found in igneous and metamorphic rocks. Limestone is found in sedimentary rocks. Plateau region of India such as Daccan and chota nagpur plateau provides the rich level of mineral distribution. Uses of Minerals: Some minerals which are usually hard are used as gems for making jewellery. Copper is used in almost everything from coins to pipes. Silicon is used in almost everything from coins to pipes. Silicon is used in the computer industry which is obtained from quartz. Aluminium is used in automobile, airplanes, bottling industry, building and in kitchen cookware. Mica is used to make electrical appliances and glass making industries. Iron and steel is used in every indurstry. Distribution of Minerals in India: Iron: Jharkhand, Odisha and Chattisgarh Bauxite: Jharkhand, Odisha and Chattisgarh Mica: India is the leading producer of mica in the world. Jharkhand, Bihar, Andhra Pradesh are major producing states. Gold: Kolar in Karnataka Conservation of Minerals: Minerals are the non-renewable resources. It is necessary to reduce wastage in process of mining. Recycling of metals is the way to conserve mineral resources. over exploitation is harmful for environment as well. · Power Resources: Power resources are of two types: (a) Conventional Resources, (b) Non-conventional Resources We need power resources for industry,domastic use, agriculture, transport, communication and defence. Conventional Sources of Minerals: The energy resources which have been in common use for a long time are known as conventional sources. Firewood and fossil fuels are two main conventional energy sources. Fossil fuels comprises of Coal( known as burried sunshine), Patroleum (known as black gold), Natural Gas and Hydroelectricity. Non-Conventional Sources of Minerals: Non-conventional sources of energy are renewable in nature. Solar energy, wind energy, tidal energy, etc. are the examples of non-conventional sources of energy. They are more expensive as it needs technological upgradation. India has a great potential for Solar energy.

The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore. The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals.

The primary methods used to extract minerals from the ground are:

Underground mining
Surface (open pit) mining
Placer mining

The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Higher-grade metallic ores found in veins deep under the Earth’s surface can be profitably mined using underground methods, which tend to be more expensive. Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods. Many industrial minerals are also mined this way, as these ores are usually low in value and were deposited at or near the Earth’s surface. In a surface mine, hard rock must be drilled and blasted, although some minerals are soft enough to mine without blasting.

Mineral as a “homogenous, naturally occurring substance with a definable internal structure. These are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Minerals are usually found in 'ores'.

Mineral is defined as a “homogenous, naturally occurring substance with a definable internal structure.” Minerals are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Rocks are combinations of homogeneous substances called minerals.

Mode of Occurrence of Minerals

Minerals are usually found in “ores”. The term ore is used to describe an accumulation of any mineral mixed with other elements. Minerals generally occur in the following forms:

In igneous and metamorphic rocks, minerals may occur in the cracks, crevices, faults or joints.
In sedimentary rocks, a number of minerals occur in beds or layers.
The decomposition of surface rocks and the removal of soluble constituents also forms the minerals.
Minerals also occur as alluvial deposits in sands of valley floors and the base of hills.
The ocean waters contain vast quantities of minerals.

Rani Lakshmibai of Jhansi demanded the company to recognize her adopted son as the heir of the kingdom after the death of her husband. But the British refused to accept her adopted son as the ruler of Jhansi. By ‘Doctrine of Lapse’ introduced by Lord Dalhousie, if an Indian ruler died without a male heir his kingdom would ‘lapse’ and such kingdom would be annexed by the British Empire. However, the Company, confident of its superiority and military powers, turned down her pleas.

Yogita Ingle 5 years, 3 months ago

State and religion are two different entities. If state incorporates a particular religion, it becomes a theocratic state. In a theocratic state, the right of minority religions are absorbed and fringed by the larger/popular religion often causing violence and discrimination.

The practice of separating religion from state is called secularism. It advocates freedom to practice any religion individually. The state would not endorse or enforce any religion and it would not participate in any religious matters.

How does constitution determine the authority and legitimacy of law

Posted by Badal Rani Jamatia 5 years, 3 months ago

CBSE > Class 08 > Social Science

1 answers

Yogita Ingle 5 years, 3 months ago

FIRST things first. Law has to be understood in context of usage. So if it were a democracy with a socialist manifestation of laws, like India: Law has a social purpose. If it were authoritarian regimes, law is a command of sovereign.
Determination of legitimacy or the power of sanction against contravention of laws is the domain of sovereign power. In International Law, every State is sovereign. But within that State, sovereignty to make, execute or enforce laws may lie in the hands of: Executive, Legislature or Judiciary. In UK, Legislature, the Parliament is sovereign (Parliament of UK can do everything except turning a man into woman and woman into man). Indian Constitution is sovereign. Legislature, Executive and Judiciary derive their powers, duties from this written document. Thus although traditionally Legislature makes laws, it may be held illegitimate or ultra vires the Constitution by Judicial Interpretation of the Constitution.
