Erdkunde

• What is the term used to describe a group of fuels formed from ancient plants and organisms?

  Fossil Fuels
• What does the term "Fossil Fuels" refer to?

  It refers to fuels formed from ancient plants and organisms.
• During which geological period were fossil fuels formed?

  Carboniferous period
• Why are fossil fuels sought after as energy sources?

  Because they have a high energy density, providing a lot of energy from a small amount of fuel.
• What are some applications of fossil fuels?

  They are used for electricity production and transport fuels.
• What causes geopolitical issues related to fossil fuels?

  Scarcity caused by the natural geographic allocation of these resources.
• Why are fossil fuels considered non-renewable resources?

  Because they take millions of years to form and cannot be replenished in a lifetime.
• What is one major problem associated with fossil fuels?

  They cause climate change by releasing CO₂ and other gases.
• What are the key advantages and disadvantages of geothermal energy?

  Advantages (+):

  • Environmentally friendly
  • Great for heating & cooling
  • Reliable and renewable

  
  

  Disadvantages (-):

  • Dirty water
  • Can cause earthquakes
  • High initial costs
  • Location-specific
• Why is geothermal energy considered an energy source for the future?

  Because it is environmentally friendly and a reliable renewable source for heating and cooling.
• What is one question related to solar power mentioned in the material?

  What country uses solar power?
• What are three major countries involved in geothermal development?

  Philippines, Indonesia, and USA

  • Potential for land subsidence
• What are some components involved in geothermal power generation?

  Reservoir, magma, electric mains, turbine, steam, hot water, injection well, cooling tower
• What is the first step in the geothermal energy process?

  To access/to drill
• What is the role of the generator in the geothermal energy process?

  It converts the steam into electricity
• What is the final step in the geothermal energy process?

  To rise
• What is geothermal energy?

  Geothermal energy is the heat from the Earth's interior.
• How is geothermal energy observed in nature?

  It can be observed through erupting volcanoes and geysers.
• What is located deep below the Earth's crust?

  A layer of hot molten rock called magma is located deep below the Earth's crust.
• How does the heat below the Earth's surface compare to oil and natural gas resources?

  The heat just over six miles below the surface contains 50,000 times more energy than all the oil and natural gas resources in the world.
• What can be created by releasing a small amount of heat from below the Earth's surface?

  Electricity can be created by releasing a small amount of heat in the right way.
• How does geothermal energy generate electricity?

  A well drilled a couple of miles deep captures rising hot water and steam, which spins a turbine to produce electricity.
• What is the status of geothermal energy as a renewable source in the US?

  Geothermal is one of the least explored sources of renewable energy in the US.
• Why might people not think much about geothermal energy?

  Most people probably don't spend much time thinking about it.
• What are the environmental benefits of geothermal energy?

  It is a pollution-free renewable source of energy.
• How long has geothermal energy been a reliable source of energy?

  Geothermal energy has been reliable for at least 4.5 billion years.
