Plate Boundaries | 3 Types: Divergent, Convergent, and Transform |
Divergent Boundary | Pulling apart. Example: Iceland |
Convergent Boundary | Going together. Example: Himalayas |
Transform Boundary | Sliding past each other. Example: San Andreas Fault Line |
Subduction | Continent - Oceanic crust collision; Most volcanoes are created from this; Happens at Convergent Boundaries |
Ring of Fire | 80% of volcanoes are in this. Circles one large plate |
Hot Spots | A breach in tectonic plates |
Athenosphere | Below the Lithosphere |
Weathering | The breaking down of rocks through rain or wind |
