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/convergent plate boundaries||Destructive/divergent 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):
The World's Plate Boundaries
This diagram shows all of the earth's plate boundaries:
You should be able to identify the boundary types by looking at the directions of the arrows, which indicate compression, tension or lateral force.
