Relate plate motion to boundary processes
The idea
Divergent boundaries separate plates; convergent boundaries bring them together.
Step by step
- Divergent boundaries separate plates; convergent boundaries bring them together.
- At transform boundaries, plates move sideways past each other.
- Specific landforms depend on the plate materials and setting as well as motion.
Example
Two plates move away from each other at a mid-ocean ridge. Which boundary type fits?
Answer
divergent boundary
The plates diverge, allowing new crust to form between them.
