• What is a natural hazard?

• Why is a volcanic eruption that does not affect people considered a natural phenomenon rather than a natural hazard?

  Because it does not pose a risk to people or property.
• What does the term "hazard" imply in the context of natural hazards?

  The term "hazard" implies risk.
• What is the definition of a natural disaster?

  A natural disaster is a natural hazard that results in a high death toll and significant damage to buildings and infrastructure.
• How are natural hazards classified?

  They are classified by the processes that cause the hazard to occur.
• What are the different types of natural hazards?

  • Tectonic hazards (e.g., earthquakes, volcanic eruptions, tsunamis)
  • Atmospheric hazards (e.g., hurricanes, droughts)
  • Geomorphological hazards (e.g., flooding)
  • Biological hazards (e.g., forest fires, disease pandemics)
• What causes tectonic hazards?

  Tectonic hazards are caused by the movement of tectonic plates.
• Where do tectonic hazards usually occur?

  They usually occur where two tectonic plates meet.
• What are atmospheric hazards caused by?

  Atmospheric hazards are caused by high and low pressure weather systems.
• How do geomorphological hazards differ from atmospheric hazards?

  Geomorphological hazards happen on the Earth's surface, while atmospheric hazards are related to weather systems.
• What factors affect geomorphological hazards like flooding?

  Factors such as rock type and relief of the land affect geomorphological hazards.
• What are biological hazards?

  Biological hazards involve living organisms, such as forest fires and disease pandemics.
• How is flooding classified in relation to natural hazards?

  Flooding is classified as a geomorphological hazard.
• What is a connection between geomorphological hazards and atmospheric hazards using flooding as an example?

  Flooding is a geomorphological hazard caused by factors like rock type and relief, but it can also be caused by excessive rainfall, which is an atmospheric hazard.
• How can some natural hazards be caused by human activities?

  Some natural hazards, like forest fires, can be caused by arson or carelessness with campfires or barbecues.
• What are examples of human-caused natural hazards?

  • Forest fires caused by arson
  • Campfires or barbecues left unattended
