Section A

• What are the 3 types of Natural Hazards?

  Flooding, Geological and Atmospheric
• Give 3 examples of a Geological Hazard?

  Earthquakes, Volcanic eruptions and Landslides
• Give 3 examples of Flooding hazards?

  Tsunamis, Storm surges and Avalanches
• Give 3 examples of Atmospheric Hazards?


  Droughts, Heatwaves and Wildfires
• What is 'Hazard risk'? And give example


  Means the chance of being affected by a natural hazard.
• What is a Hazard risk?


  Means the chance of being affected by a natural hazard. For example where you live.
• As population grows..


  more people are exposed to natural hazards
• What are the four factors which increase the risk?

  Urbanisation, Poverty, Farming and Climate change
• What is an earthquake?

  A sudden shaking or trembling of the ground caused by the movement of tectonic plates.
• Where do earthquakes occur?

  Margins of slowly moving tectonic plates
• What are the layers of our Earth?

  Inner core, Outer core, Mantle and Crust
• What are the 2 types of crust?

  Oceanic and Continental
• How do plates move?

  Driven by the convection currents within the mantle and under gravity
• Where do plates separate?

  Constructive margins
• Where do plates collide?

  Deconstructive plates
• Where do plates slide by each other?

  Conservation margins
• What are some examples of primary effects of an Earthquake?

  Destroyed buildings and injuries
• What are some secondary effects of an earthquake?

  Fires and landslides
• What are the 2 earthquakes to compare?

  Nepal and Chille
• What are some reasons people live at risk from tectonic hazards?

  Too poor, effective monitoring, they are rare, no knowledge of risks
• What are the four main management strategies?

  Monitoring, Prediction, Protection and Planning
• What is Global atmospheric circulation?

  The large-scale movement of air around the Earth, driven by temperature differences and the rotation of the Earth.
• Global atmospheric circulation drives the worlds weather
• What is a tropical storm?

  A tropical storm is a low-pressure system that forms over warm ocean waters and is characterized by strong winds and heavy rainfall.
• What are 3 examples of tropical storms?

  Hurricanes, Cyclones and typhoons.
• How do tropical storms form?

  1. Rising air draws evaporated water vapour from ocean which then condenses in clouds
  2. Condensing releases heat which powers storm and draws more water vapour
  3. Multiple thunderstorms join to make one big storm
• What are some features of a tropical storm?

  Strong winds, heavy rainfall, thunderstorms, and low pressure.
• What are the most destructive storms on earth?

  Tropical Storms
• What was Typhoon Haiyan?

  One of the strongest Category 5 storms ever and included alot of destruction of many things
• Explain some Primary effects from Typhoon Haiyan?

  6300 killed, 40000 homes destroyed, wind damage
• Explain some Secondary effects of Typhoon Haiyan?

  shortages of power, 6m jobs lost, flooding causing landslides
• What were the immediate and long term responses for Typhoon Haiyan?

  I - evacuation centres set up, overseas aid and field hospitals
• What is weather?

  Describes the day to day conditions of the atmosphere
• What are the 5 weather hazards?

  1. Hurricanes 2. Tornadoes 3. Floods 4. Droughts 5. Blizzards
• The Uk has experienced an increase in the number of extreme weather events in recent years.
• Rising sea levels mean that storm surges can cause greater coastal erosion and flooding
• Climate change means there will be more intense precipitation leading to floods
• Increased temperatures lead to more evaporation which leads to increased rainfall
• Increased temperatures lead to more evaporation which increases rainfall intensity
• What is some evidence for climate change?

  Increased global temperatures, rising sea levels and shrinking ice caps
