• What is 'hazard risk'?

  It is the chance of being affected by a hazard.
• How does the amount of flooding relate to tropical storms?

  Tropical storms can cause significant flooding events.
• What are the three main groups of natural hazards?

  They include meteorological, geological, and hydrological hazards.
• Why do some natural hazards become disasters?

• How can hazard management help with flooding?

  It can reduce the impact of flooding events.
• What should be done to manage flood hazards effectively?

  Implementing early warning systems and infrastructure improvements.
• What are the main types of natural hazards and their characteristics?

  • Blizzards: Frequent and damaging, affecting property.
  • Tropical storms: Common and potentially dangerous.
  • Earthquakes: Sudden and can cause significant destruction.
  • Droughts: Gradual and can lead to water shortages.
• What factors affect hazard risk and management?

  • Population density: Higher density increases risk.
  • Preparedness: Better preparedness reduces impact.
  • Environmental conditions: Certain areas are more vulnerable.
  • Economic resources: Wealthier areas can manage hazards better.
• What are the consequences of natural hazards becoming disasters?

  • Loss of life and injuries
  • Economic losses and property damage
  • Displacement of communities
  • Long-term environmental impacts
• What is the main reason why natural hazards are easy to assess?

  They assess risks after weighing advantages and disadvantages
• What knowledge is important for assessing natural hazards?

  A good knowledge of the hazard
• What is the chance of living in a hazardous area?

  Little chance of where to live
• Are all hazards considered disasters?

  No, not all hazards are disasters
• What factors affect risk?

  Population growth increases exposure to hazards
• What are the four factors that increase risk from natural hazards?

  • Urbanization: densely populated urban areas concentrate risk
  • Poverty: housing shortages lead to risky ground building
  • Farming: attraction of fertile soil puts people at risk
  • Climate change: global warming raises sea levels and generates extreme weather
• How does urbanization affect risk from natural hazards?

  Densely populated areas concentrate those at risk
• How does poverty contribute to risk from natural hazards?

  Housing shortages lead to building on risky ground
• How does farming increase risk from natural hazards?

  Attraction of fertile soil puts people at risk
• What impact does climate change have on natural hazards?

  It raises sea levels and generates extreme weather
• What are the most deadly natural hazards?

  • Floods
  • Storms
  • Earthquakes
  • Droughts
• What happens as populations grow in relation to hazard risk?

  More people are exposed to hazard risks
• Why is the number of earthquakes or volcanic eruptions not changing?

  Natural hazards remain constant despite population growth
• Why are more people at risk from natural hazards despite unchanged numbers of earthquakes or eruptions?

  Population growth increases exposure to hazards
