Divergent Boundary

1. Divergent Boundary A plate boundary where the plates pull away from each other As the plates pull away, magma rises to fill the gap. The molten material cools and forms a type of mountain called a mid-ocean ridge. Example: Mid-Atlantic Ridge

2. Mid-Atlantic Ridge – world’s longest mountain chain When the sea floor gets larger, this is Called sea-floor spreading

3. Transform Boundary This boundary is where two plates slide past each other. The two plates grinding past each other, creating seismic waves, resulting in earthquakes! Example: San Andreas Faultline

4. San Andreas Fault

5. Convergent Boundaries This boundary occurs when two plates push against one another. What forms depends on the type of crust.

6. Continental/Continental Collision When two pieces of continental Crust collide, this causes the rock layers to buckle upward, creating FOLDED MOUNTAINS. Example: Himalayan Mountains

7. Continental/Oceanic Collision - Subduction Zones If a piece of continental crust collides with a piece of oceanic crust, the denser oceanic crust subducts or dives under the continental crust. The oceanic plate melts and creates a volcano! Subduction Zone Animation
