2. Types of Boundaries – Convergent
Plates come together
Denser oceanic crust, is subducted under the lighter continental crust.
Island Arc
Volcanic mnt. Range
Folded mnt. range
Trench
Subduction Zone

3. Folded Mnt. Range
Island Arch/ Volcano mnt. Range
The Aleutian Islands

4. Types of Boundaries – Divergent
Plates pull apart to allow new crust to emerge
continental crust pulls apart = forms a rift valley
oceanic crust pulls apart = forms a ocean ridge
Atlantic Ocean grows about 2-3 cm/y

5. Rift Valley
Ocean Ridge

6. Types of Boundaries – Transform
Plates move horizontally past each other, causing crust to deform or fracture
Characterized by faults

7. There are two type of Faults:
1. Strike Slip: two pieces of land move horizontally

8. There are two type of Faults:
2. Reverse: two pieces of land move vertically

9. San Andres Fault
