FAQs on What are Fossil Fuels? Video Lecture - Science Class 8

1. What are fossil fuels?
Ans. Fossil fuels are natural resources that are formed from the remains of plants and animals that lived millions of years ago. They include coal, oil, and natural gas, and are used as a source of energy.
2. How are fossil fuels formed?
Ans. Fossil fuels are formed over millions of years through the process of decay and compression of organic matter. The remains of plants and animals are buried under layers of sediment, which undergo heat and pressure, transforming them into fossil fuels.
3. What are the advantages of using fossil fuels?
Ans. Fossil fuels provide a reliable and abundant source of energy. They are easy to extract and transport, and can be used in various applications such as electricity generation, transportation, and heating. They have played a crucial role in powering industrialization and economic growth.
4. What are the environmental impacts of using fossil fuels?
Ans. The use of fossil fuels is associated with several negative environmental impacts. Burning fossil fuels releases greenhouse gases, such as carbon dioxide, which contribute to climate change. They also release pollutants that can harm air quality and human health. Additionally, the extraction of fossil fuels can cause habitat destruction and pollution of water sources.
5. Are there any alternatives to fossil fuels?
Ans. Yes, there are several alternative sources of energy that can replace fossil fuels. These include renewable energy sources such as solar power, wind power, hydropower, and geothermal energy. These alternatives are considered more sustainable and have lower environmental impacts compared to fossil fuels. However, their widespread adoption and integration into existing energy systems require further technological advancements and investments.
