1 Slide 1

2 Slide 2 Preparation before starting this Revision unit you need to have:- Sorted you theory notes and produced a contents page Have your case studies completed Introduction This unit is to give you 30 minutes of Geography Revision on the Volcanoes and Earthquakes topic. Work through the tasks and stick to the timings. You could work through this unit more than once

3 Slide 3 You may begin….. Record down your start time

4 Slide FeatureVolcanoEarthquake Distribution Where Distribution When A: What is the global distribution of different types of natural hazard? 1.Complete this table 2.Compare and Contrast the global distribution of Volcanoes and Earthquakes

5 Slide What natural processes cause different types of natural hazards? 3 What is (i) An Earthquake (ii) A Fault (iii) The Focus (iv) The Epicentre (v) The Richter Scale

6 Slide What is (i) A volcano (ii) The vent (iii) A pyroclastic flow (iv)Magma (v) Lahar

7 Slide How the movement of tectonic plates cause earthquakes and volcanoes 5 Complete the table Type of plate boundary Description of changesEarthquake/ volcanic activity Constructive Destructive Conservative

8 Slide Look at the map of tectonic plates. Give an example of (i) Plates moving away from each other (ii) Plates moving towards each other (iii) Plates moving past each other

9 Slide How do natural hazards affect people and places in parts of the world with different levels of development? VolcanoEarthquake PRIMARY-effects SECONDARY - effects 9 Complete the table to show the Primary and secondary effects for these hazards

10 Slide Look at the data 10. How does level of economic development influence the severity of the impact? MEDCLEDC Laquila ItalySichuan China Nos of deaths Nos of injured Nos displaced Nos homeless ,000,000+ Nos buildings destroyed 10,00015,000,000 Cost £ $ 16 billion $20 billion $

11 Slide You must learn a case study of i) one tectonic event in an LEDC, 11. Complete this table LocationTime and Date StrengthExtent What happened Effects on people Primary Secondary Effects on buildings Primary Secondary Effects on Economy Primary Secondary Response Short term How was the event predicted

12 Slide You must learn a case study of i) one tectonic event in an MEDC, 12. Complete this table LocationTime and Date StrengthExtent What happened Effects on people Primary Secondary Effects on buildings Primary Secondary Effects on Economy Primary Secondary Response Short term How was the event predicted

13 Slide How can people and places be protected from the impact of natural hazards? 19. Complete the table BuildingPlanningEducation Earthquake Volcano

14 Slide A range of methods are used to attempt to reduce the impact of natural hazards 20 Complete the table with examples from your case studies Hazard Management Modify the eventModify Human VulnerabilityModify the Loss Environmental ControlPrediction and warningAid Hazard resistant designCommunity PreparednessInsurance

15 Slide How do each of these factors affect response? Response Frequency Type Areal reliability Speed of onset Magnitude Location Technology available Level of Education Level of Development (MEDC or LEDC) Rural or Urban
