Plate Tectonics HW Packet
Word Bank Section One What are Plate Tectonics?: change crust upper shape surface mountains volcanoes tectonic jigsaw trenches constant valleys
Word Bank Section Two What is Plate Tectonics? why geology theory molten seafloor increase answers new created
Word Bank Section Three Why do the tectonic plates move? asthenosphere plastic shape breaking flows (used twice) carries circulation convection temperature differences heated cycle
rise cools
Word Bank Section Four What are plate boundaries? meet plate relative transform neither nor slide
friction earthquakes San Andreas Fault transform
Section Four p. 2: Divergent fills move gap away ocean seafloor spreading mid-ocean ridges
ridge valley rift Iceland Eurasian
towards convergent collide continental oceanic volcanoes trench older two Japan subducts
two slam equally Himalayas mountains taller
oceanic subduction (used twice) removal sinks
