HKDSE Geography/M1/Plate Boundaries

The narrow zone between two adjacent plates is called a plate boundary. Three Types of Plate Boundaries Let's review the three types: Constructive/divergent plate boundaries Destructive/convergent plate boundaries Conservative plate boundaries Convection currents which are Rising/Diverging Sinking/Converging / cause plates to Diverge from each other Converge/collide into each other Slide past each other and create Tensional force Compressional force Shear/lateral force This diagram shows the three types of boundaries (transform plate boundaries = conservative plate boundaries, but that term is not accepted in Hong Kong): 600px The World's Plate Boundaries This diagram shows all of the earth's plate boundaries: 600px You should be able to identify the boundary types by looking at the directions of the arrows, which indicate compression, tension or lateral force.
