    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.

    Formation of Fossil Fuels

    • Formation of coal and petroleum takes millions of years, involving high pressure and temperature.
    • Remains of ancient plants and animals buried deep in the earth's crust undergo transformation into fossil fuels.

    Coal

    • Solid fossil fuel formed from remains of plants, such as ferns and swamps, in the carboniferous period (300 million years ago).
    • Classification of coal based on moisture content and hardness:
      • Peat: soft, brown, high in moisture content
      • Lignite: brown, soft, high in moisture content
      • Bituminous: black, hard, low in moisture content
      • Anthracite: black, hard, low in moisture content

    Petroleum

    • Liquid fossil fuel formed from remains of marine organisms, such as plankton and algae, in the ocean.
    • Found in sedimentary rocks, often with natural gas.
    • Refined into various products, including:
      • Gasoline
      • Diesel fuel
      • Jet fuel
      • Lubricants
      • Petrochemicals

    Uses of Coal and Petroleum

    • Coal used for:
      • Electricity generation
      • Industrial processes (e.g. steel production)
      • Domestic heating
    • Petroleum used for:
      • 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 causes respiratory problems and other health issues.
    • Mining and drilling for these resources lead to environmental degradation and habitat destruction.
