a. Physical hazards of tropical cyclones (high winds, intense rainfall, storm surges, coastal flooding, landslides) and their impact on people and environments.
This statement asks you to identify the physical hazards of tropical cyclones and explain their impact on people and environments. High winds, including sustained speeds of 119 km/h or more in hurricanes and typhoons, damage buildings, power lines and crops. Intense rainfall causes flooding and landslides, particularly on saturated slopes. Storm surges are abnormal rises in sea level driven by low pressure and onshore winds, and they cause coastal flooding in low-lying areas. Impacts on people include deaths, injuries, displacement and loss of livelihoods. Impacts on environments include erosion, saltwater contamination of soils and freshwater, and damage to coastal ecosystems such as mangroves. Strong answers link each hazard to a specific consequence rather than listing hazards alone.
b. Why some countries are more vulnerable (physically, socially and economically) than others to the impacts of tropical cyclones.
Explain why some countries suffer greater harm from the impacts of tropical cyclones than others. Physical factors include low-lying coasts, weak building standards and the loss of coastal mangroves. Social factors include high population density, poverty, limited education and difficulty reaching shelters. Economic factors include limited insurance, reliance on farming or tourism and little money for rebuilding. Use a named country as a case study and show how these factors combine. A densely populated delta with poor housing may suffer far more than a wealthier coast facing a similar storm. Link each factor to a specific impact, such as flooding or long-term economic disruption.
Your focus
- Identify five physical hazards associated with tropical cyclones.
- Explain how storm surge and intense rainfall lead to flooding and landslides.
- Describe at least two impacts of tropical cyclones on people and two on environments.
Show all 6 objectives
- Identify physical, social and economic factors that increase vulnerability to tropical cyclones.
- Explain how a named factor increases the impact of a cyclone on a specific country.
- Explain how two or more factors combine to make one country more vulnerable than another.
Topic 1: 1.5 Tropical cyclones present major natural hazards to people and places exam tips
Marking Points
- Identifies high winds as a hazard and describes damage to buildings, power supply and crops.
- Explains that intense rainfall causes flooding and landslides, especially on saturated slopes.
- Explains that storm surges are abnormal sea-level rises driven by low pressure and onshore winds, causing coastal flooding.
- Describes impacts on people, including deaths, injuries, displacement and loss of livelihoods.
- Describes impacts on environments, such as erosion, saltwater contamination of soils and freshwater, and damage to mangroves and other coastal ecosystems.
- Explains a physical factor, such as low-lying coastal land that floods more deeply, and how it increases vulnerability.
- Links a social factor, such as high population density or limited education, to a specific impact like delayed evacuation.
- Explains an economic factor, such as limited insurance, and how it slows recovery after a storm.
- Uses a named country as a case study to support the explanation with accurate, specific detail.
- Shows how physical, social and economic factors interact rather than listing them as separate points.
Examiner Tips
- 💡Organise your answer by hazard, then give at least one impact on people and one impact on the environment for each.
- 💡Use the terms storm surge and coastal flooding precisely, because they describe different stages of the same event.
- 💡Check that each impact is linked to a hazard using a connective such as because, leading to or as a result.
- 💡Plan three strands (physical, social and economic) before writing, and check that each one is developed rather than mentioned.
- 💡Select one named country and use its specific features rather than generic examples.
- 💡End each paragraph by linking the factor to a clear consequence, such as loss of life or long-term economic disruption.
Common Mistakes
- Lists hazards without stating a consequence; corrects this by linking each hazard to a named impact on people or environments.
- Attributes all deaths to wind damage; corrects this by including flooding, landslides and storm surge as causes of loss of life.
- Treats storm surge and coastal flooding as the same process; corrects this by explaining that the storm surge is the cause and coastal flooding is one outcome.
- Describes wind speed and damage without explaining why a particular country is more vulnerable; add the human or infrastructure cause.
- Treats wealth as the only cause of vulnerability; include physical and social factors as well.
- Assumes all low-income countries suffer identical losses; explain the specific local conditions of a named place instead of generalising.
