__Divergent-__ Magma rises and pushes plates apart __Convergent -__ A plate collides with or dives under another __Transform__ - Two plates grind against each other

__Convergent Boundaries__
 * occur where a plate or ocean dives,subducton
 * plate melts and often spewed out in volcanic eruptions or ashes.
 * form deep trenches
 * cause collisions
 * two board classifications are subduction and collision boundaries

__Divergent Boundaries__
 * In oceans, magma form deep in the Earth's mantle, it rises toward the surface and pushes apart the plates.
 * Mountains and volcanoes rise aling the seam.
 * A mid-ocean ridge would then mark the boundary between the plates
 * have rift valleys
 * the process is called sea-floor
 * movements along fracture zones are along earthquakes

__Transform Boundaries__
 * Where two plates grind past each other along what are called strike-flip faluts.
 * Boundaries don't produce spectacular features like mountains or oceans.
 * Motion triggers large earthquakes
 * fracture zones are segments of mid-ocean ridges
 * occurs in the state California

__Facts__
 * Six major plates are named as continents
 * Plate tectonics describes the intricate design of a complex, living in a state of dynamic flux.
 * Plate tectonics is formed by earthquakes and volcanoes
 * Melting and the plate go together with weather/erison
 * 14 countries have plate tectonics
 * 80 percent of earthquakes occur along the rim of the Pacific Ocean.
 * One is in pennsylvania
 * Weathering is mechanical

 * __Eurasian Plate__
 * __Phillppine Plate__
 * __Australian Plate__
 * __North American Plate__
 * __Caribbean Plate__
 * __Cocos Plate__
 * __Nazca Plate__
 * __South American Plate__
