9. Four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other. Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear. http://pubs.usgs.gov/gip/dynamic/understanding.html

Map of East Africa showing some of the historically active volcanoes (red triangles) and the Afar Triangle (shaded, center) -- a so-called triple junction (or triple point), where three plates are pulling away from one another: the Arabian Plate, and the two parts of the African Plate (the Nubian and the Somalian) splitting along the East African Rift Zone. http://pubs.usgs.gov/gip/dynamic/East_Africa.html
