1. Plate Interactions How do tectonic plates interact with one another?
What are the different types of plate boundaries?
Where are real world examples of each type?
What features are associated with each type?

2. Convergent Boundaries
Oceanic - Continental
Oceanic crust is more dense than continental crust
Subduction Zones
Dense oceanic crust is forced down into the mantle under the continental crust.
Features
Volcanic mountain chains
Oceanic trenches

3. Convergent Boundaries

4. Convergent Boundaries
Oceanic – Oceanic
Oceanic crust subducts under oceanic crust
Features
Volcanic island arcs
Oceanic trenches
Examples
The Aleutian Islands, Japan, the Philippines

6. Convergent Boundaries

7. Convergent Boundaries

8. Convergent Boundaries
Continental– Continental
Continental crust is too buoyant to subduct.
Tectonic Uplift- Crust is forced upward
Features
High plateaus and mountain ranges
Examples
Himalayan Mountains
Tibetan Plateau

Ex: Mid-Atlantic Ridge
Continental Rift Zones
Ex: East African Rift Valley

17. Transform Boundaries Plates slide past one another Example
No Subduction
Example
San Andreas Fault
Pacific Plate is sliding NW relative to the N. American Plate
