GLOBAL HAZARD revision sheet 2 – how PLATE TECTONICS shape our world Theory Layers of the earth describe: Case Studies Diagram identify the layers Haiti quake 12/01/2010 Accurately LOCATE Haiti Port au Prince The Gonave platelet The Caribbean plate The Enriquillo- Garden fault Cuba Florida Inner core Outer core Mantle Crust(lithosphere) Challenge: What is the ASTHENOSPHER? Draw a labelled diagram to show the features of these margins: Constructive What type of plate margin was it? Consequences of the quake (primary/secondary) Destructive Response to the quake ( include details of what it is like today) Conservative Collision Why has it been so difficult to rebuild Haiti after the quake? Draw a diagram to show how hotspots are formed What are the key differences between deep and shallow focus earthquakes? Earthquake mitigation Why are earthquakes hard to predict? How do these technologies work: Interferograms Shield volcanoes Strainmeters laser beams Foreshock monitoring composite volcanoes Building earthquake resistant buildings: How do THESE ideas work ( with diagrams) Base isolation X and K bracing Weight dampners Early Warning Systems – How does the shake alert system work?
