The document discusses natural resources like coal and petroleum. It defines fossil fuels and asks questions about carbonisation, resources used to obtain petrol and diesel, gases used in fertilizer production, resources to obtain naphthalene balls, and refining. Further questions cover the formation of coal and petroleum, constituents of petroleum and their uses, CNG as a fuel, advantages and disadvantages of petroleum, and risks of using oil. It also asks about comparisons of coke and coal as fuels and definitions of coke, coal tar, petrochemicals, and destructive distillation of coal.
