hazards

• What is hazard risk?

  The probability of a natural hazard occurring
• What defines a natural hazard?

  A natural event threatening people and property
• What is a conservative plate margin?

  Where two tectonic plates slide past each other
• What occurs at a constructive plate margin?

  Magma adds new material to diverging plates
• What happens at a destructive plate margin?

  Two plates converge, causing subduction
• What is an earthquake?

  A sudden movement within the Earth's crust
• What are immediate responses to a disaster?

  Reactions during and right after the disaster
• What are long-term responses to a disaster?

  Reactions occurring weeks or months later
• What is monitoring in the context of natural hazards?

  Recording physical changes to forecast hazards
• What is a plate margin?

  The boundary between two tectonic plates
• What does planning involve for natural disasters?

  Actions to help communities respond and recover
• What is prediction in the context of natural hazards?

  Forecasting when and where hazards will strike
• What are primary effects of a natural event?

  The initial impact caused directly by the event
• What is protection in relation to natural hazards?

  Actions taken to reduce impact before hazards
• What are secondary effects of a natural event?

  After-effects that occur as indirect impacts
• What is a tectonic hazard?

  A natural hazard caused by tectonic plate movement
• What is a tectonic plate?

  A rigid segment of the Earth's crust
• What is a volcano?

  An opening in the Earth's crust for eruptions
• What is extreme weather?

  Weather significantly different from usual patterns
• What is global atmospheric circulation?

  The worldwide system of winds transporting heat
• What is a tropical storm?

  An area of low pressure with spiral winds
• What is mitigation in relation to natural hazards?

  Actions to reduce long-term risk from hazards
• What is the Quaternary period?

  The geological period from 2.6 million years ago
• What does adaptation mean in the context of natural events?

  Actions taken to adjust to natural events
• What are the types of plate margins?

  • Conservative plate margin
  • Constructive plate margin
  • Destructive plate margin
• What are the responses to natural hazards?

  • Immediate responses: reactions during and after the disaster
  • Long-term responses: reactions weeks or months later
• What are the effects of natural events?

  • Primary effects: initial impacts directly caused
  • Secondary effects: indirect impacts occurring later
• What are the actions taken regarding natural hazards?

  • Monitoring: recording changes to forecast hazards
  • Planning: enabling community responses and recovery
  • Prediction: forecasting when and where hazards will strike
  • Protection: reducing impact before hazards occur
  • Mitigation: reducing long-term risks from hazards
  • Adaptation: adjusting to natural events
