<strong>Alfred Wegener</strong>- The creater of the theory of plate tectonics

<strong>Theory of plate tectonics</strong>-that large plates bearing continents and oceans move about on the planet because of earthquakes, mountain building, and valcanoes

<strong>Divergent Boundaries-Plates pull away from each other</strong>

<strong>Convergent Boundaries- Plates move toward each other</strong>

<strong>subduction- creates volcanoes (two plates move in together and one melts underneath the other)</strong>

<strong>tranformation- two plates rub against eath horizontally causing earthquakes</strong>

<strong>plate collisions- two plates hit into each other and move upward. This forms mountains</strong>
