ThinkRankCoal and Petroleum
Coal and petroleum formed over millions of years from buried organisms and are therefore exhaustible fossil fuels. Their products power transport, industry, and homes, but extraction and burning cause pollution and greenhouse-gas emissions. Conservation and cleaner alternatives are necessary for energy security and environmental protection.
Learning Objectives
- •Explain fossil fuel formation
- •Explain refining creates products
- •Explain energy has consequences
Key Concepts
Fossil fuel formation
Heat, pressure, time, and burial transformed ancient organic matter into coal, petroleum, and natural gas.
Refining creates products
Petroleum is separated into useful fractions such as petrol, diesel, kerosene, lubricants, and bitumen.
Energy has consequences
Fossil fuels are energy-dense but finite; mining, drilling, transport, and combustion create ecological and health costs.
Terminology
Historical Insight
Petrochemicals
Plastics, detergents, synthetic fibres, and paints may use petroleum products, showing why energy resources also enter material supply chains.
Fuel conservation
Public transport, efficient appliances, and renewable electricity can reduce fossil-fuel demand.
Quick Check
Why are coal and petroleum called exhaustible?
What happens in a refinery?
Why should fossil fuels be conserved?
