Fossil Fuels

• What are the three types of fossil fuels mentioned?

  Coal, oil, and gas
• How are fossil fuels formed?

  Over millions of years from organic remains
• What is the early atmosphere primarily composed of?

  Carbon dioxide
• What process takes in carbon dioxide and produces oxygen?

  Photosynthesis
• What prevents the decomposition of plant remains in marshy wetlands?

  Lack of oxygen or acidic conditions
• What is the role of sediment in the formation of coal?

  It covers and compresses plant remains
• What creates coal from plant remains?

  High temperature and pressure
• What is crude oil formed from?

  Plankton
• Where do plankton settle to form crude oil?

  In mud on the seabed
• What conditions prevent plankton from decomposing?

  Absence of oxygen
• How is natural gas primarily formed?

  From plankton, similar to oil
• What is the main component of natural gas?

  Methane
• Why do we often find natural gas near oil deposits?

  They are formed in similar ways
• What do old fossil fuels contain that is significant?

  Trapped carbon
• Where did the carbon in fossil fuels originally come from?

  Carbon dioxide taken in by photosynthesis
• What will be discussed in a later video?

  The effects of burning fossil fuels
• Where can students find questions on fossil fuels?

  In the ization workbook
• What is the non-renewable nature of fossil fuels?

  They will run out if used continuously
• How do fossil fuels relate to atmospheric gases?

  They contain carbon from carbon dioxide
• What geological processes transform organic matter into fossil fuels?

  Compression and heat over time
