Study Notes
Formation of Coal and Petroleum
- Both coal and petroleum are formed from the remains of ancient plants and animals.
- The process of formation takes millions of years, involving high pressure and temperature.
- The remains are buried deep in the earth's crust, where they undergo transformation into fossil fuels.
Coal
- Coal is a solid fossil fuel.
- Formed from the remains of plants, such as ferns and swamps, that lived in the carboniferous period (300 million years ago).
- Different types of coal:
- Peat: soft, brown, and high in moisture content.
- Lignite: brown, soft, and high in moisture content.
- Bituminous: black, hard, and low in moisture content.
- Anthracite: black, hard, and low in moisture content.
Petroleum
- Petroleum is a liquid fossil fuel.
- Formed from the remains of marine organisms, such as plankton and algae, that lived in the ocean.
- Can be found in sedimentary rocks, often in combination with natural gas.
- Refined into various products, including:
- Gasoline
- Diesel fuel
- Jet fuel
- Lubricants
- Petrochemicals
Uses of Coal and Petroleum
- Coal:
- Electricity generation
- Industrial processes (e.g. steel production)
- Domestic heating
- Petroleum:
- Transportation (e.g. cars, trucks, airplanes)
- Industrial processes (e.g. manufacturing, construction)
- Electricity generation
- Domestic heating
Environmental Impacts
- Burning coal and petroleum releases greenhouse gases, contributing to climate change.
- Air pollution from combustion can cause respiratory problems and other health issues.
- Mining and drilling for these resources can lead to environmental degradation and habitat destruction.
