Plate Boundaries

The gradual movement of the continents across the earth. In 1912, Alfred Wegener introduced this theory but he did not fully understand what caused the plates to move.

• sea floor spreading

• Continental Drift Theory

• Uplift

• Divergent boundaries

Where two plates are sliding horizontally past one another. No destruction or construction - Crust is deformed or fractured (earthquakes). Example - San Andreas fault
