**Vocabulary**
slow motion, driven by convection currents in the mantle//
 * Plates-t**he lithosphere broken into separate sections
 * Scienctific theory//-//** //a well tested concept that explains a wide range of observations//
 * Plate tectonics//-//** //a geological theory that states that pieces of Earth's lithosphere are in constant,
 * Faults-** //breaks in the Earth's crust where rocks have slipped past each other//
 * Transform boundary-** a place where two plates slip past each other,moving in opposite directions
 * Divergent boundary-** //a place where two plates move apart//
 * Convergent boundary//-//** //a place where two plates come together//
 * Rift Valley-** //a deep valley that forms where two plates move apart//

**Outline**
= =

**Introduction**
= =
 * //1965 J. Tuzo Wilson//
 * //Wilson thought the lithosphere was broken into pieces//
 * //pieces called plates.//
 * //the plates fit closely together//

**Theory of Plate Motion**

 * //formation//
 * //movement//
 * //subduction//

**Plate Boundaries**

 * //Transform boundary//
 * //Divergent boundary//
 * //Convergent boundary//

**Transform Boundaries**

 * //Earthquakes occur frequently along these boundaries//

= =

**Divergent Boundaries**
= =
 * //Occur along the mid-ocean ridge//
 * //Also occur on land//
 * //Rift valleys occur near divergent boundaries//

= =

**Convergent Boundaries**
= =
 * //When 2 plates converge, they cause a collision//
 * //Oceanic crust and oceanic crust//
 * //Continental crust and oceanic crust//
 * //Continental crust and continental crust//
 * //Density desides which plate comes on top//
 * //Can create mountains//

**The Continent's Slow Dance**

 * //plates move at amazingly slow rates//
 * //1-10 centimeters per year!//
 * //that's how fast your fingernails grow!//
