NCERT Solutions for Class 10 Social Science Geography Chapter 5 - Minerals and Energy Resources

This chapter discusses the different minerals that can be found and their primary sources. A mineral can be outlined as a present substance with determinable chemical composition and internal structure. They are present in nature in numerous forms starting from the toughest diamond to the softest talc. Rocks are a combination of homogenized substances referred to as minerals. Minerals are typically found in "ores".

The term ore is employed to explain the associated accumulation of any mineral mixed with alternative parts. They are generally classified as Metallic & Non-metallic minerals. Metallic minerals are classified as Ferrous minerals, which account for concerning three- fourths of the full price of the assembly of metallic minerals: for example - ore, Manganese. And Non-ferrous minerals that include copper, bauxite, lead, metal, and gold. These minerals play an important role in a variety of metallurgic, engineering, and electrical industries. For example, Limestone is found in rocks composed of calcium carbonates and magnesium carbonates. It is the essential material for the cement trade and essential for smelting ore within the furnace. Minerals area unit a non-renewable resource. Continued extraction of ores ends up in the depletion of minerals. So, it's vital to require the necessary steps so that natural resources will be employed in a planned and property manner.

The chapter also discusses the different energy resources that can be used. Energy resources can be classified as Conventional and Non-Conventional sources. Conventional sources are non-renewable sources of energy that have been used for a long time. It includes fuel, bovine dung cake, coal, petroleum, gas and electricity. Whereas, Non-Conventional sources are renewable energy sources that are continuously replenished by natural processes. It includes wind, tidal, geothermal, biogas and solar energy. Every sector of the financial system, including agriculture, industry, transport, business and domestic, requires inputs of energy for operation. There's an associate imperative to develop a proper path for energy development.

There are several different ways in which people can contribute to saving lots of energy resources, such as using public transport systems rather than individual vehicles, switching off electricity when not in use and using power-saving devices and using non-conventional sources of energy.
