• A naturally occurring substance that has a definite chemical composition and physical properties is called a mineral.
• Minerals are not evenly distributed over Earth's surface. They are concentrated in particular areas or crock formations and are formed in different types of geological environments, under varying conditions.

Introduction

•  The Earth is composed of various kinds of elements. These elements are in solid form in the outer layer of the Earth.
• About 98% of the total crust of the Earth is composed of eight elements namely oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium.
• The rest is composed of titanium, hydrogen, phosphorus, manganese, sulphur, carbon, nickel and other elements.

Minerals

• Mineral is a naturally occurring organic and inorganic substance, having an orderly atomic structure and a definite chemical composition and physical properties.
• Magma is the primary source of minerals. Magma reaches the Earth's surface through volcanic eruptions. As it reaches the surface, it crystallizes to form minerals.
• Minerals such as coal, petroleum and natural gas are organic substances found in solid, liquid and gaseous forms.
• The International Mineralogical Association (IMA) recognised around 5,413 official minerals in November, 2018

Physical Features of Minerals:

1. External Crystal Form: Determined by the internal arrangement of molecules, such as cubes, octahedrons, hexagonal prisms, etc.
2. Cleavage: Tendency to break in specific directions, producing relatively plane surfaces.
   • Result of the internal arrangement of molecules.
   • May cleave in one or more directions and at various angles to each other.
3. Fracture: Crystal breaks in an irregular manner, not along planes of cleavage.
   • Breaks along random directions.
4. Lustre: Describes how light is reflected on the mineral's surface.
   • Each mineral has a distinctive lustre, such as metallic, silky, glossy, etc.
5. Colour: Some minerals have characteristic colours determined by their molecular structure.
   • Impurities may also contribute to the colour of certain minerals.
6. Streak: Colour of the ground powder of any mineral.
   • May be the same or differ from the mineral's colour.
7. Transparency: Physical property of light passing through the material.
   • Can be categorized as transparent, translucent, or opaque.
8. Specific Gravity: Ratio of the weight of a substance's volume to the weight of an equal volume of the reference substance.
   • No unit for specific gravity since it is a ratio comparison.
9. Structure: Particular arrangement of individual crystals, categorized as fine, medium, coarse-grained, fibrous (separable, divergent, radiating).
10. Hardness: - Measured on a scale from 1 to 10 using ten minerals, including talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, and diamond.

• The rate of formation is much smaller than the rate at which 
• Economic development has brought with it increasing consumption of all types of minerals leading to increase in prices
• It is necessary to reduce wastage in the process ofmining
• Recycling of metals is another way in which the mineral resources can be conserved.

Uses of Minerals

Energy Resources

• Energy is an important factor in an economy. The demand for energy has increased with socio-economic development in the world. Some of the energy resources are exhaustible Somen-renewable, eg, coal and mineral oil out many are renewable, e.g. water and solar energy
• Potential of water energy is more in those regions Phere water discharge of the rivers is high, rainfall is heavy and running water is available throughout the year.
• Solar energy is more dependable and univers applicable.
• The increasing demand of the energy and the energy crisis of 1973, in the world have given impetus to research and development of non-conventional sources of energy.

Classification of Energy Resource

• Energy plays a vital role in our lives. We need energy for industry, agriculture, transport, communication and defense.
• It may be broadly categorized as conventional non-conventional sources

Conventional Sources

• Conventional sources of energy are those, which have been in common use for a long time.Firewood and fossil fuels are the two main conventional energy sources. Firewood and cattle dung cake are most common in rural India.

Firewood

• More than 70% of the energy needs in rural households are fulfilled by firewood and coal, as estimated. Firewood, widely utilized for cooking and heating, contributes to over 50% of the energy consumed by villagers in our country.
• Fossil fuels like coal, petroleum, and natural gas serve as the primary sources of conventional energy, originating from the remains of plants and animals buried for millions of years. However, the reserves of these minerals are limited, and their consumption rate by the growing global population surpasses their formation rate, leading to potential exhaustion.

Coal

• Coal, the most abundant fossil fuel, plays a crucial role as a domestic fuel, in industrial processes like iron and steel production, steam engines, and electricity generation. Despite being fundamental to the industrial revolution, its significance has diminished with the advent of mineral oil and natural gas.
• Found in sedimentary rock seams, coal's key attributes include combustibility and volatility. The majority of coal formed during the carboniferous period, known as Buried Sunshine due to the submergence of natural vegetation.
• According to the International Energy Agency (IEA) estimates for 2022, the top five coal producers were China, India, Indonesia, Australia, and the USA. In India, coal-producing regions include Raniganj, Jharia, Dhanbad, and Bokaro in Jharkhand.

Bituminous:

• Description: Black and shiny coal.
• Carbon Content: Ranges from 70 to 90%.
• Characteristics: Generates a smoky flame and leaves behind a significant amount of ash. 
• Named bituminous due to the production of tar (bitumen) when heated. Found in larger quantities, especially in coal obtained from Gondwana formation.

Lignite:

• Description: Also known as brown coal.
• Carbon Content: Ranges from 45 to 70%.
• Characteristics: Burns with high smoky flames. Originates more recently than anthracite and bituminous coals, containing a higher proportion of vegetal matter.

• US oil consumption was high in the early 1970s, while US oil production declined. In 1973, 36% of energy consumption was foreign oil, up from 22% in 1970.
•  Arab-Israeli conflicts had escalated, causing tension between the US and Arab nations. In 1973, an international oil embargo ensued.
• Middle Eastern countries, engaged in religious and political conflicts, halted petroleum exports to Western nations, including the United States and the Netherlands, in protest over their involvement in Arab-Israeli conflicts. The Organization of the Petroleum Exporting Countries (OPEC) cartel contributed to rising gas prices in the early 1970s.
•  OPEC, formed in 1960, aimed to establish a common policy, set trade rules, and determine prices for its vast fuel supplies. Its member nations produce over half of the world's oil and supply approximately 80% of oil imported by non-member nations.
• OPEC, comprising Algeria, Ecuador, Gabon, Indonesia, Iran, Iraq, Saudi Arabia, the United Arab Emirates (UAE), and Venezuela, has become a highly influential group in world politics due to its significant oil supply. More than half of its members are Middle Eastern countries.
