Minerals and energy resources Rating:
Minerals and energy resources are essential for the functioning of modern societies. They are used in a wide range of applications, from the production of electricity and transportation fuels to the manufacturing of consumer goods and construction materials. These resources are non-renewable, meaning that they cannot be replaced once they have been used up. As a result, it is important to use them efficiently and to find sustainable alternatives to ensure that future generations have access to the resources they need.
There are two main types of minerals: metallic and non-metallic. Metallic minerals, such as copper, iron, and gold, are used in the production of a variety of products, including electronics, automobiles, and construction materials. Non-metallic minerals, such as limestone and clay, are used in the production of glass, ceramics, and cement.
Energy resources can be divided into two main categories: fossil fuels and renewable energy sources. Fossil fuels, such as coal, oil, and natural gas, are formed over millions of years from the remains of plants and animals. They are non-renewable and their extraction and use contribute to climate change through the release of greenhouse gases into the atmosphere. Renewable energy sources, such as solar, wind, and hydropower, are replenished naturally and do not contribute to climate change.
Minerals and energy resources are often found in countries that have a high demand for them. This can lead to conflict over access to these resources, as well as environmental and social issues related to their extraction and use. For example, the extraction of fossil fuels can lead to air and water pollution, as well as habitat destruction. Renewable energy sources, on the other hand, have fewer negative impacts on the environment and can help to reduce reliance on fossil fuels.
As the world's population continues to grow and demand for resources increases, it is important to find ways to use minerals and energy resources more efficiently and to transition to renewable energy sources. This can involve investing in energy-efficient technologies, such as LED light bulbs and electric vehicles, as well as supporting the development of renewable energy sources, such as solar and wind power. By making these changes, we can ensure that we have access to the resources we need while also protecting the environment for future generations.

Describe the distribution of coal in India. It is the second highest energy source after refining into various products like furnace oil, diesel, petrol, kerosene, etc used in India after coal. Write a note on the conservation of energy resources. Resources may be classified in many ways. As we know coal is a non- renewable source of energy that has been in use for a long long time and with time its stores are depleting.

Example - Iron ore is used in the manufacturing of steel, bauxite is the ore of aluminium, etc. Hazards of Mining:- Why does the mining industry is called a killer industry? Use of Compressed Natural Gas CNG for vehicles to replace liquid fuel is also increasing. Lignite is poor-quality coal with high moisture content. Mumbai High is the major producer in India. Earth's crust is made up of minerals.
It is found in greater depths. Ans: As Rajasthan, Gujarat, and Maharashtra are located in India's tropical, temperate Zone, it receives adequate solar radiation, which is the most favorable consideration for solar energy generation. It is an important mineral due to its excellent electrical conductivity. What are the differences between conventional and non-conventional energy? Distribution of Different Types of Minerals in India India is one of the richest countries in terms of mineral resources. One should note that a major portion of the world's energy supply comes from non-renewable resources such as coal, oil etc. The major categories of minerals are ferrous and non-ferrous minerals.
Class 10 Geography Chapter 5 Minerals and Energy Resources Notes
India has abundant resources of good quality iron ore. Large reserves of natural gas have been discovered in the: a Ganga — Godavari Basin b Ganga — Yamuna Basi c Ganga — Brahmaputra Basin d Krishna — Godavari Basin Answer Answer: d Krishna — Godavari Basin Large reserves of Natural gas have been discovered in the Krishna-Godavari Basin. Classification of Minerals:- Minerals are mainly classified as metallic, non-metallic, and energy minerals. Metallic Minerals:- Minerals containing metals are called metallic minerals, like gold, silver, tungsten, etc. The smaller occurrences are called veins and the larger are called lodes. It has a low carbon content and low heating capacity and high moisture content. The per capita consumption of electricity in a place is considered as an index of development.
It can be clear, black, green, red, yellow or brown. There are several different types of minerals that have accumulated over time forming layers one after another and created the core crust of the Earth. These resources are used to generate electricity and power various machines. India has a deficiency of this mineral. Coal is always considered to be an important energy resource because of the benefits it has got to offer to mankind. Further it tells us how these minerals are actually made up of metals which can be extracted through various processes of refinement and purification.

Solar Energy India is a tropical country. Thus, petroleum refineries provide raw materials to the industries above, thereby acting as a 'nodal industry. It is a conventional form of energy resource that has been responsible for generating power, heat and steam and also acts as a domestic fuel mainly in India. Our mineral intake represents only about …………………… percent of our total intake of nutrients. The largest wind form cluster is located in Tamil Nadu from Nagar coil to Madurai. Alluvial deposits or Placer deposits :- Some minerals are found in the sands of valley floors and at the base of hills.
