Plate Tectonics A scientific revolution unfolds III Three types of tectonic plate boundaries based on their relative motions 1  Transform plate boundaries Special locations in the tectonic plate mosaic Transform plate boundaries 2 The pacific plate consist of 3 long transform boundaries Queen Charlotte San Andreas Alpine fault 3 The pacific plate consist of 3 long transform boundaries San Andreas 4  Primary source of water for San Francisco located along the San Andreas Fault Crystal springs reservoir The pacific plate consist of 3 long transform boundaries Queen Charlotte San Andreas Alpine fault 5 Major ruptures along the Alpine Fault occurred between 100‐350 year intervals Last major earthquake in 1717 Spreading ridges are broken up by fracture zones Fracture zones 6  Earthquake activity at ridges indicate sliding movement Fracture zone 2 1 Transform faults only occur between axes of ridge segments Axes of Mid‐ocean ridge segments Fracture zones 7 Special locations in the plate mosaic Pacific plate 8 Intersection of 3 tectonic plates forms a triple junction Ridge‐ridge‐ridge triple junction Hotspot volcanoes are not plate boundary volcanoes 9 Volcanic ages of seamounts increase away from Hawaii 10 Abnormal upwelling of magma forms a hot spot Seamount A seamount chain is formed by a hot spot 11 Yellowstone 12  Yellowstone What would be the first sign of getting closer to the next super eruption? Yellowstone What feature of an eruption would disrupt humanity across the world? 13 Iceland 14 Iceland, one of the most active volcanic regions 15
