Transform Boundary
1. Transform Boundary: plates scrape across each other in opposite directions
•Typical geologic activity = earthquake•Example: San Andreas Fault in California
Divergent Boundary• Divergent Boundary: plates move apart
•Typical geologic activity = rift valleys, mid-ocean ridges, and volcanoes•Examples: Mid-Atlantic Ridge, Great Rift Valley
Convergent Boundary: Subduction• Convergent Boundary (subduction): Plates push together and
one goes underneath the other
•Typical geologic activity = trenches, earthquakes, and volcanoes•Example: Marianas Trench
Mariana Trench
Convergent Boundary: Buckling
• Convergent Boundary (buckling): plates push together and both plates push up
•Type of geologic activity: mountains•Example: the Himalayas
