Tectonics

Global distribution of plates
 * Plates and plate movement**


 * Plate margins**

Tensional plate margins (constructive / diverging margins) [|more info (diagram)] Compressional plate margins (destructive converging margin) [|more info (diagram)]

Fold mountains [|more info (great animation and info)] Earthquakes: focus and epicentre [|more info (animation)] Volcanoes; composite and shield [|more info (good animation)]
 * Characteristic features and formation of:**

Occurrence and measurement of earthquakes

Human activity in fold mountains [|more info]

[|Mt St Helens] (BBC article and video) [|Mt St Helens case study] (excellent detailed study thanks to Rob Chambers) Primary and secondary effects LEDC MEDC [|Montserrat case study] (simple) Short, medium and long term responses [|Montserrat]  (more detail, really easy to follow)
 * Case study of a volcanic eruption**

Primary and secondary effects LEDC MEDC I would [|revise the Bam earthquake] as the LEDC example Short, medium and long term responses [|Comparing two earthquakes] (from Geography in the News)
 * A case study of an earthquake**

Advantages Why would people live around such a dangerous mountain as Vesuvius? Think about tourism, farming, minerals, power Disadvantages [|Vesuvius]  is a great case study Different values and attitudes to the hazard of tectonic activity
 * Settlement in areas of tectonic activity**
