1. Plates make up the crust of the Earth
Can you see any similarities between the plate boundaries shown here and
The ones you found with your earthquake and volcano data?

2. Tectonic Plates Come In Two Flavors
Oceanic Plates are thinner and denser
They are represented by your fruit roll up pieces
Continental plates are thicker and less dense
They are represented by your graham crackers
Tectonic Plates Can Interact in Three Basic Ways
Convergent Boundaries converge or come together
Divergent Boundaries diverge or move apart
Transform Boundaries slide past each other
We will model these interactions with our food

3. Divergent Boundaries
The Mid Atlantic Ridge

4. Oceanic Convergent Boundaries
The Marianas Trench

5. Ocean To Continental Convergent Boundary – Subduction Zone
Mt. Spurr
Alaska
The Pacific Ring of Fire

6. Continental Convergent Boundary
Himalaya Mountains

7. Transform Boundary
San Andreas Fault
