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…
You are to work independently on creating a profile for each of the key mechanisms of plate movement…
Internal heating…
- Define the mechanism
- Draw a labelled diagram of its process
- Provide an example in the world
Convection Currents…
- Define the mechanism
- Draw a labelled diagram of its process
- Provide an example in the world
Plumes…
- Define the mechanism
- Draw a labelled diagram of its process
- Provide an example in the world
Subduction…
- Define the mechanism
- Draw a labelled diagram of its process
- Provide an example in the world
Rifting at Plate Margins…
