Understanding why natural hazards occur can help countries to manage or prevent their consequences. Case studies illustrate the impact of natural hazards in the short and long term.
What conditions lead to the formation of a tropical storm?
Low air pressure, temperatures under 27ºC and air spiralling downwards
Low air pressure, temperatures above 27ºC and air spiralling downwards
High air pressure, temperatures above 27ºC and air spiralling upwards
How can tropical storms be predicted?
Where do most major earthquakes occur?
Mainly along the boundaries of tectonic plates
Mainly in the centre of tectonic plates
Everywhere - there is no pattern
What causes an earthquake?
Plates move together, stick and jerk free
Plates move apart and the crust shakes
Plates move side by side, stick and suddenly jerk free
What causes a tsunami?
An underwater earthquake
An earthquake underground
Low air pressure
What equipment is used to help predict earthquakes?
Where do most explosive volcanic eruptions happen?
At constructive plate boundaries
At destructive plate boundaries
At conservative plate boundaries
Which method is used to predict a volcanic eruption?
Change in air pressure
Increase in seismic activity
