1 Plate tectonics lab

2 1 Convergent Boundaries Oceanic to Continental boundary impact - The oceanic plate ALWAYS subducts (goes under) Called Subduction: Oceanic crust pushed down to mantle, where it is melted and rises. See picture  Forms: trenches

3 2 Convergent Boundaries Continental to Continental boundary impact Mountain formation Causes: Uplift(mountain building) Rocky Mountains

4 3 Divergent Boundaries Two Oceanic plates-Forms Mid ocean-rifts Called: sea floor spreading: makes new crust Mid-Atlantic Rift

5 4 Divergent Boundaries Two continental plates- Form rift valleys Called Subsidence which forms valleys Great rift Valley formed by divergent plates

6 5 Transform Boundaries Transform plates create earthquakes! Oceanic or Continental plates rubbing San Andreas fault: California
