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
