Case Study Questions
I. Petrol and diesel are the two most widely used fuels for vehicles. Petrol, diesel, and kerosene are obtained from petroleum. Petroleum, along with natural gas and coal are commonly called a fossil fuel. They are formed essentially from the remains of micro¬organisms and plants that got buried deep inside the earth, and were converted to petroleum, natural gas, and coal. It takes millions of years for these fuels to form. Natural gas is used for cooking and generating electricity. Nowadays, it is also used in the form of Compressed Natural Gas (CNG) as a fuel for vehicles. It is a cleaner fuel than petrol or diesel. Coal is mainly used for the production of electricity. It is found in several parts of India.

II. Resources which get renewed, replenished, or restored within a reasonable period of time are called renewable resources. Air, water, and forests are some of the examples of renewable natural resources. Nature renews them. We should use our natural resources judiciously. On the other hand, fossil fuels take millions of years to form. They are found in limited quantities, and once used, they get exhausted. They are not produced or replenished within a reasonable period of time. These resources are called non-renewable resources. Examples of non-renewable natural resources are minerals, soil, rocks, coal, petroleum, and natural gas.
