 * transform boundary** - a place where two plates slip past each other moving in opposite directions.

 * rift valley** - a deep valley that forms along the divergent boundary.

Introduction

 * 1965 ; Wilson
 * Wilson thought the lithosphere was broken into pieces
 * pieces called plates.
 * the plates fit closely together.

Plate Motion

 * Transform boundary
 * Divergent boundary
 * Convergent boundary

The Continent's Slow Dance

 * plates move at amazingly slow rates.
