There are three main types of plate movement:
1.
Divergent:
2 plates spreading apart
2.
Convergent:
2 plates coming together (subduction or collision)
3.
Transform:
2 plates sliding past each other
Click on the
? and fill in the blanks below.
1. What forms at divergent boundaries?
2. Sea floor spreading is an example of what type of boundary?
3. In a convergent boundary, what plate gets subducted?
4. What can result as a process of oceanic crust colliding with continental crust?
5. Which fault is the most well known transform boundary?
6. What can result as two plates transform past one another?
