fossil fuels

• What are the three types of fossil fuels mentioned in the video?

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

  Fossil fuels are formed over millions of years from the remains of ancient organisms.
• Why are fossil fuels considered non-renewable?

  Because they will run out if we keep using them.
• What is the process of coal formation?

  • Formed from remains of ferns and trees
  • Occurs in marshy wetlands
  • Lack of oxygen or acidic conditions prevents decomposition
  • Covered with sediment and compressed
  • High temperature and pressure create coal
• How is crude oil formed?

  • Formed from plankton (tiny sea plants and animals)
  • Plankton settle in mud on the seabed after dying
  • Lack of oxygen prevents decomposition
  • Compressed by sediment and converted by heat and pressure
• What is the formation process of natural gas?

  • Mainly consists of methane
  • Formed from plankton in a similar way to oil
  • Often found near oil deposits
• What key fact is mentioned about old fossil fuels?

  They contain trapped carbon that was part of carbon dioxide taken in by photosynthesis.
• Where can students find questions on fossil fuels?

  In the provided ization workbook.
• What will be discussed in a later video regarding fossil fuels?

  The effects that burning fossil fuels is having on the planet.
