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.
