    Lesson01 tectonic boundaries Lesson01 tectonic boundaries Presentation Transcript

    • Layers of the Earth song
    • Unit 3 Natural Hazards3.1 OverviewBy the end of this unit I will: This bit will be covered•Be able to define a natural hazard as we learn•Know that different types of natural about each of thehazard have specific global distributions specific•Know that the movement of tectonic types ofplates cause earthquakes and hazard.volcanoes•Know that climatic conditions lead totropical storms and severe drought Today
    • Copy this diagram into your books, with the labels. Structure of the EarthWatch the video and add as many labels as you can to your picture – NOTE – the videoshows the mantle as two separate layers.
    • The surface of the earth is broken up into tectonicplates that move, causing earthquakes, volcanoes andbuilding mountains. What drives tectonic movement?
    • Put the boundaries onto your maps
    • Movie (Tectonics – Ring of Fire)
    • There are three types of plate boundaries. A boundary iswhere two plates meet.As I show you the following clips, I would like you to work out which natural hazard eachtype of plate movement can cause. Write a table in your book like below Type of plate boundary Type of hazard caused DESTRUCTIVE CONSTRUCTIVE CONSERVATIVE
    • TASKCut out and sort the cards into groups that belong together. As plates slide alongside each other they Constructive occasionally stick and pressure builds up until there is an earthquake. As plates move towards each other one slides Destructive under the other causing volcanoes. Plates move away from Conservative each other and new crust is formed.You have until the timer finishes to get all of the cards cut out and sorted!

    • WHAT HAPPENED HERE?Decide if the devastation has been Acaused by a volcano or anearthquake, and which type of plateboundary might be responsible. B C
    • Tell me two facts you have learnt from the lesson
