Outline one reason why the largest earthquakes do not always cause the most deaths?
Population density may be low so few people are present in the danger area, earthquakes can happen out at sea
1 of 10
Describe how the three P's (Predict, protect and prepare) can help to reduce the effects of an earthquake?
Knowing what to do (dropping on the ground, seeking cover), building structures being well built for them not to collapse, Temporary banks = so life can continue after the disaster
2 of 10
What are fold mountains?
Large ranges of mountains, different rock layers have crumpled, layers consist of anticlines and synclines as they have been pushed together

6 of 10
Outline the characteristics of a shield volcano?
Flat/rounded top, broad base, gentle sliding slopes and runny fast lava
7 of 10
Describe the likely global consequences of a super volcano eruption?
Impact from ash, ash would block out sunlight, temperatures could fall, difficult to grow food - crops, starvation would break out causing deaths
8 of 10
Explain the formation of a composite volcano?
Occur at destructive plate margins, Process causes a build up of pressure which causes and explosive eruption, slow flowing lava
9 of 10
Use a case study to describe the effects on a tsunami?
Japan: ruined cars, homes and boats, shifted the harbour wall, people were stranded, no electricity, no mains water supply
