FAQs on Management of Coal and Petrol Video Lecture - Class 8

1. What is coal management?
Ans. Coal management refers to the process of organizing and controlling the extraction, production, transportation, and utilization of coal resources. It involves planning and implementing strategies to ensure efficient and sustainable use of coal while minimizing environmental impacts.
2. How is coal mined and extracted?
Ans. Coal is typically mined through two methods: surface mining and underground mining. Surface mining involves removing the topsoil and rock layers to expose the coal seams. Underground mining, on the other hand, involves tunneling into the earth to access the coal. Once the coal is reached, it is extracted using various techniques, such as continuous miners or longwall mining.
3. What are the advantages of using coal as an energy source?
Ans. Coal has several advantages as an energy source. Firstly, it is abundant and widely available, making it a reliable source of energy. Secondly, it is relatively inexpensive compared to other fossil fuels. Additionally, coal-fired power plants can be built in various sizes, allowing for flexibility in meeting different energy demands. However, it is important to note that coal combustion releases greenhouse gases and pollutants, contributing to air pollution and climate change.
4. How is petrol managed and distributed?
Ans. Petrol, also known as gasoline, is managed and distributed through a complex supply chain. It starts with the extraction of crude oil from the ground, which is then transported to refineries. At the refineries, the crude oil is processed and converted into petrol and other petroleum products. The petrol is then distributed to various fuel stations through a network of pipelines, tankers, and storage facilities.
5. What are the environmental impacts of using petrol as a fuel?
Ans. The use of petrol as a fuel has significant environmental impacts. The combustion of petrol in vehicles releases carbon dioxide (CO2), a greenhouse gas that contributes to climate change. Petrol combustion also emits nitrogen oxides (NOx) and volatile organic compounds (VOCs), which contribute to air pollution and the formation of smog. Additionally, the extraction and refining of crude oil for petrol production can lead to habitat destruction, oil spills, and water pollution.
