Mechanisms of plate movement…

Syllabus Point: To know the Mechanisms of plate movement including internal heating, convection currents, plumes, subduction and rifting at plate margins

Starter: Task 1: Recap – draw four quick sketches of the types of plate boundary movement that you learnt for IGCSE…add some labels too to support your sketches…

Main Development:

Pgs. 164-165 will help you as will the youtube link below…
