1. What is the best description of a dormant volcano?

• A volcano that has never erupted
• A volcano that has erupted recently and is likely to erupt again
• A volcano that has not erupted for a long time
• A volcano that is unlikely to erupt again

2. Why does basic lava form shield volcanoes that are wide and flat?

• Because it is runny
• Because it is runny and cools slowly
• Because it is thick
• Because it is thick and cools quickly

3. What is the centre of an earthquake called?

• The focus
• The epicentre
• The subduction zone
• The plate boundary

4. Which one of the following is a scale on which earthquakes are measured?

• Beaufort
• Centigrade
• Meter
• Richter

5. Which statement is NOT true?

• The epicentre is the point directly above the focus on the earth's surface
• The further away from the epicentre, the weaker the shock waves
• Earthquakes are caused when two plates move together
• Earthquakes usually occur along constructive plate boundaries

6. How do the plates move?

• By a build up of pressure under the earth's surface
• By convection currents in the mantle
• Due to magnetic fields in the earth's atmosphere
• Due to friction between plates

7. Which statement describes best where most volcanoes and earthquakes are found?

• They are evenly distributed across the world
• They are all found in Asia and the Middle East
• They are found in the middle of plates
• They are found in long narrow belts near plate boundaries

8. What feature is found at the boundary of two oceanic plates?

• A mid oceanic ridge
• An escarpment
• Fold mountains
• A cuesta

9. What happens to rocks in the subduction zone?

• They explode
• They melt
• They contract
• They form crystals

10. Fold mountains occur most commonly along which type of plate margin?

• Collision
• Destructive
• Constructive
• Conservative

11. Which of these statements is not a reason for living in an area of tectonic activity?

• Lava and ash create fertile soils so farming is good
• Volcanic islands are useful stopping off places for long sea or air journeys
• Useful rocks and minerals are found in volcanic areas
• People only die in areas of tectonic activity if they are not educated

12. Which of these statements is true?

• Earthquakes are usually worse in LEDC's
• Earthquakes are usually worse in MEDC's
• Earthquakes are usually worse in rural areas
• Earthquakes are usually worse if they occur at night

13. Which of these will not help reduce the effects of a hazard?

• Monitoring
• Good building and road design
• Increasing the population
• Good emergency services

14. What is a seismometer?

• A measurement of how strong an earthquake is
• An instrument for measuring earthquakes
• A logarithmic scale
• A person who measures earthquakes

15. If an earthquake occurs out at sea what can be caused?

• A storm
• A tsunami
• A volcano
• A flash flood
