Answers for Worksheet

1. Minerals are substances that are formed naturally in nature. Any naturally occurring substance that has a chemical composition in it is called Minerals.

2. Minerals are generally formed in different types of geological environments and in different conditions. The formation of minerals is a natural process without any human interference. Now, minerals in nature can be identified on the basis of their colour, properties, characteristics, hardness, density, and smell in some cases. 

3. Minerals can be extracted from the Earth’s surface by mining, drilling, and quarrying. These extracting processes are mostly used for extracting metallic minerals from nature. 

4. Mining is nothing but the process of taking out minerals from the Earth is called as mining. On the other hand, open-cast mining is also known as open-pit mining and is the activity of taking minerals such as coal from the surface of the ground. 

5. Quarrying is the process of digging into the ground for minerals. It is a technique that includes drilling and blasting of rocks. Some products that are extracted using this process are marble, granite, limestone, sandstone, and many more. 

6. Some of the places around the world where iron ore, nickel, and copper are found are Europe, Canadian Shield Region, and Australia respectively. 

7. Two countries that are rich in natural gas resources are Russia and the United Kingdom. 

8. Minerals are very important in today’s world they are used by almost every industry possible. Now, some of the industries where minerals are used are the airline industry, bottling industry, building industry, and many more. 

9. Minerals are non-renewable resources i.e., they cannot be made in a very short span. It takes thousands of years for the formation of natural minerals and their concentration of them. The formation rate of such minerals is becoming smaller day by day and the consumption is increasing. Minerals must be recycled in every way possible to conserve them. 

10. Power resources are the resources that will never go dry. These resources have been very commonly used for a very long time. Power resources can be categorized into two categories and they are conventional and non-conventional resources. 

11. Conventional resources are those resources that are non-renewable in nature. These resources have been in use for a very long time in human history. Some conventional resources are firewood and fossil fuel. 

12. Fossil fuel is a natural conventional resource. Fossil fuels are filled with hydrocarbons and they are formed naturally. Such fuels are supplied in about 80 percent of the world for energy. They provide electricity, heat, petroleum, and many more. 

13. Petroleum is what keeps our car running and it is found between the layers of rocks and is drilled from oil fields that are mostly located off-shore and in coastal areas. It is drilled from the shores and then they are sent to refineries which are further turned into crude oil and varieties of products are made such as kerosene, petrol, wax, plastics, and many more. 

14. Natural gas is a naturally formed gas that contains methane and other alkane gases. It is one of the most important clean energy sources in nature. Such gases are used as fuel in many power sectors to generate electricity. 

15. Hydel power is also known as hydroelectricity. To produce hydel power rainwater or river water is stored in dams so they fall from heights. The falling water in such areas falls through pipes that have turbine blades placed at the bottom. Now, the blades turn the generator and produce electricity. 

16. Non-conventional sources are non-renewable in nature and will exhaust one day in the future. Moreover, the use of non-conventional energy causes a lot of environmental pollution. Therefore, the need of using conventional sources is highly needed. 


  1. True

  2. True

  3. False

  4. True

18. The advantages and disadvantages of hydel power are given in the table below:



Electricity can be produced at a constant rate and is renewable

The maintenance cost of hydel power dams are high

The gates used to produce electricity can be shut down if electricity is not needed

People in that part of the region are forcibly removed

They can last longer 

If flooding happens then the failure of dams increases

The water can again be used for irrigation purposes

A serious geological damage can happen while constructing the dam


  1. Solar Energy: Solar energy is the heat or light from the sun. Now, this light is collected using a range of technologies such as solar panel and are further used for daily purposes. 

  2. Wind Energy: It is an inexhaustible energy found in nature. Windmills are used to generate wind energy. Windmills are located in coastal regions and in mountain passes. 

  3. Geothermal Energy: Geothermal energy is also known as thermal energy. It is the heat that is produced deep in the Earth’s core. 

  4. Tidal Energy: Tidal energy is nothing but the energy that is generated from tides is known as tidal energy. Tidal energy can be harnessed by building dams at the narrow openings of the sea. 

20. Biogas is formed naturally; it is the organic waste such as dead plants and animals. In fact, animal dung and kitchen waste can also be converted to biogas. All of these organic wastes are decomposed by bacteria and as a result, it becomes a mixture of methane and carbon dioxide.
