 * __Dynamic earth__**

Ocean- Continent **Continent- Continent**
 * Divergent Boundaries**
 * Magma rises and pushes plates apart
 * Causes mountains and volcanoes to form
 * Make the oceans bigger
 * Plates are in Lithosphere
 * Magma squirts out in-between plates
 * The great river valley was formed from Divergent boundaries
 * Mid Atlantic Ridge was formed from Divergent boundaries
 * Mid Atlantic Ridge was certitude when the North American and African plate pulled apart
 * Made of crust
 * Transform Boundaries**
 * Two plates grind against each other and slide by San Andreas Fault[[image:sanandreasfault1.jpg width="186" height="282" align="right" caption="San Andreas Fault"]]
 * most collisions are in water
 * Trigger earthquakes
 * Don't create spectacular features such as mountain or valleys
 * Found in lithosphere
 * Made of crust
 * San Andreas Fault is an example of a transform boundary
 * San Andreas Fault was created when the Juan de Fuca Plate and the Cocos collided
 * Convergent boundaries**[[image:Convergentplateboundary1.jpg width="262" height="205" align="right"]]
 * When plates collide and one dives under the other.
 * Forms trenches
 * Himalayas were formed when the Indian plate hit the Eurasian plate
 * Himalayas are an example because one plate went under the other creating mountains.
 * Made of crust
 * There is three subgroups
 * Ocean- Ocean**
 * Characteristic include deep sea trenches, island acres and earthquakes.
 * Characteristics include deep sea trenches bordering continent, volcanoes on coast and earthquakes.
 * Characteristics include high continental mountain chains and earthquakes.
