Coal and petroleum are two important natural resources that we use every day. These are called “fossil fuels” because they are made from the remains of plants and animals that lived millions of years ago.
Coal is a black or brown rock that is burned to produce energy. It is used to generate electricity and power many industries. Petroleum, also known as “oil,” is a thick, sticky liquid that is extracted from the ground. It is used to make fuels like gasoline and diesel, as well as many other products.
In this chapter, we will learn more about the formation, uses, and impact of coal and petroleum through a series of multiple-choice questions (MCQs). These MCQs will help you understand the key concepts related to coal and petroleum, which are part of the Class 8 Science syllabus.
NCERT Solutions for Class 8 Science provide detailed explanations for these MCQs, ensuring that you have a strong understanding of the topic.
