Natural hazards risk factors a card sort

Transcription

1 Student tasks 1. Cut up the cards below. 2. Read all of the risk factors and explanations carefully. Match each risk factor to its correct explanation. 3. Identify and explain which risk factor you feel is the most important. 4. Identify and explain which risk factor you feel is the least important. 5. Write a sentence for each pair of risk factors and explanations and provide a case study example and/or expansion. Natural factors This will not prevent a natural hazard occurring but it may reduce the impacts and allow more people to survive. This is how often a hazard occurs. This is the position of a country or region in the world. This allows richer countries (MEDCs) to respond quickly and effectively to natural hazards than poorer countries (LEDCs). This is the size of the event. These elements such as geology, topography and relief can all affect both the risk and the severity of natural hazards. This is the number of people living in a place and the spread of people in an area or country. This can influence the risk from natural hazards in many ways, e.g. whether the hazard occurs during the day or night Page 1 of 5

2 Student tasks 1. Cut up the cards below. 2. Read all of the risk factors and explanations carefully. Match each risk factor to its correct explanation. 3. Identify and explain which risk factor you feel is the most important. 4. Identify and explain which risk factor you feel is the least important. 5. Provide a case study / example and further expansion for each pair of risk factors and explanations. Even in poorer countries (LEDCs), people are usually well aware of natural hazards. The level of education will not prevent a natural hazard occurring but it may reduce the impacts and allow more people to survive. This is how often a hazard occurs. If a particular hazard occurs many times, then people may become more used to it. They will be able to prepare for the natural hazard and cope more effectively after it has occurred. Larger and less frequent hazards, such as large magnitude earthquakes, will take people by surprise. The position of some countries means they are more likely to be at a greater risk from natural hazards. The Philippines for example, is prone to earthquakes, tsunamis, volcanic eruptions, flooding and typhoons because of its global position Page 2 of 5

3 Natural Factors Richer countries (MEDCs) are usually more economically developed and have greater available to be able predict, prepare and respond to natural hazards than poorer countries (LEDCs). Richer countries, for example, can build stronger earthquake proof buildings and use satellite technology to track hurricanes. The size and scale of the hazard event is linked closely to the risk it poses to people and the environment. Typically, larger or stronger events pose more risk to people and property than smaller events and cause more damage and a higher number of injuries and deaths. Factors like geology, topography and relief can all affect both the risk from natural hazards and the severity of their impact. For example, low-lying flat areas are more likely to be flooded when a tsunami occurs. The number of people living in a place and how they are spread across the area can greatly affect the severity of a natural hazard. Generally, the fewer people living in an area, e.g. in the countryside, the lower the number of injuries and deaths will occur. This can influence the effects of a natural hazard in several ways, e.g. if a hazard occurs when people are asleep they will receive no warning causing a higher number of injuries and deaths Page 3 of 5
