Main	1.   TDIT 2.   Students use diagram below to mark 12 volcanoes (see list below) on world map and label if they are on destructive or constructive plate margins – then say if shield or composite. 3.   Students draw and label NT p13 C&D and add 2 examples of each, country and plate margin. 4.   Volcano photo quiz
Plenary	a.   What are shield volcanoes and what type of plate margin would you find them on? b.   What are composite volcanoes? Plate margin type? c.   Name 2 shield and 2 composite volcanoes. Describe their location.
