PLATE BOUNDARY INTERACTIONS separating coming together sliding past one another PLATE BOUNDARY INTERACTIONS

DIVERGENT BOUNDARIES Plates are pushed aside as magma rises to crust Creates ridges rift valley ridge ridge and rift valleys animation DIVERGENT BOUNDARIES

basalt magma & rocks Iceland Ethiopia East African rift valley volcanism at the rift Ethiopia East African rift valley

Plates slide past each other – side by side, or up and down Creates faults and earthquakes rift valley ridge ridge TRANSFORM BOUNDARIES

San Andreas - a strike-slip fault Animation index San Andreas - a strike-slip fault

Ex: Mid-Atlantic ridge transform and divergent boundaries

What boundaries are present? divergent transform divergent What boundaries are present?

What boundaries are present? subduction convergent divergent What boundaries are present?

What can you identify & explain?
