Here are potential responses to the natural hazards practice questions: 1. Earthquakes and volcanic eruptions are caused by movement and activity within the earth's plates. At plate boundaries, plates collide, slide past each other or move apart. The friction between plates builds up stress over time and is suddenly released in earthquakes or volcanic eruptions. [3 marks] 2. A divergent plate boundary is where tectonic plates are moving away from each other. [1 mark] 3. Tropical storms form over warm tropical oceans where sea surface temperatures are above 27°C. Convection currents carry warm, moist air upwards which condenses to form thunderstorms. Coriolis force causes the winds to

11. • 29th August 2005
• USA (formed as Category 5 in Bahamas first, made landfall
in USA as Category 3 hurricane)
• Worst affected = Florida, Louisiana (especially New Orleans
which is 2-3metres below sea level naturally)
• 155mph winds
• 80% of New Orleans city evacuated
• Breached levees (flood defences) with a 10m+ storm surge
• 1200 drowned. 600 died from disease such as cholera
(unusual for MEDC). Total deaths at least 1833.
• 1million homeless (800’000 for over a year in temporary
housing). Residents evacuated to superdome.
• Criticised for poor government response (e.g. George Bush
slow to declare emergency or launch FEMA rescue)
• $90.9billion damages (costliest disaster in US history).

– Human responses to the storm
– Mapping and prediction of the storm
– Preparation for the storm (evaluate this)
You will be chosen at random to present

21. Why do people live in areas at
risk of tropical storms?
1. Find a map that shows the distribution of
tropical storms
2. Describe the location / pattern of the
worst affected areas. Choose specific
countries.
3. Suggest reasons (based on research)
why people choose to live in risk areas
(social, economic, environmental
reasons). What benefits?

22. How to prepare for a tropical
storm
• Create a guide aimed at Louisiana residents.
• The aim is to advise local residents how they should
prepare for a hurricane
• Must also be understood by non-English speakers
(Louisiana has a high Hispanic population). So think
about images & translations.
• Include:
– Possible effects of hurricanes:
• Storm surge
• Wind speed
– Evacuation plans – what to pack, where to go
– Emergency supplies at home
– Protecting homes and businesses from damage
– Protecting against looting

25. SOLO Hexagons
1. Mindmap all you can remember about the
tropical storms including the case studies
2. Write each point out onto a hexagon
3. Now try to match these hexagons up to
other hexagons to MAKE LINKS
4. CHALLENGE: how many connections
can you make? Try for at least 3 sides of
the hexagons to connect.
5. Use the pattern to structure your

27. Cyclone Nargis
• Worst natural disaster in Burma / Myanmar
• Began as an intense tropical depression on April 27th 2008 in the Bay
of Bengal. Made landfall over Irrawaddy delta in Burma on May 2nd.
• Meteorologists initially thought storm would track over Bangladesh
• However, the storm changed direction and headed towards Burma:
this was not realised immediately due to a lack of prediction and
monitoring equipment in the region
• Category 4 storm on the Simpson–Saffir scale
• 130-145mph winds. 600mm of rain fell.
• 138’000 people were killed
• $10 billion damage occurred
• 75% of hospitals and clinics were badly destroyed or damaged
• Diarrhoea, dysentery & skin infections afflicted the survivors who were
crammed into monasteries, schools and public buildings for safety
• Burma’s military government was resistant to foreign aid. UK donated
£17million but much was lost on black market & looting.
