Scores 19. $400 At midocean ridges, lava erupts from the __________ and runs the length of a ridge 21. $600 The age of the rocks on the ocean floor get progressively ____________ the further away from the mid-ocean ridge. 23. $800 The process of the oceanic plates moving away from the midocean ridges is known as this 25. $1000 Scientists are able to observe “stripes” in the ocean floor because these minerals freeze in different directions when the polarity of the planet changes. 31. $600 This is why oceanic crust is subducted under continental crust (also why older oceanic crust is subducted under newer crust) 33. $800 As crust is subducted, it melts into magma which may rise and eventually form these 42. $600 This method of heat transfer is the driving force behind the plate movement 48. $200 This is the type of boundary where midocean ridges form 50. $400 The type of boundary formed by a lateral fault (plates grinding past each other in a horizontal direction) 55. $800 What is the deeper hotter mantle material rises (less dense) and then cools, becomes denser, and sinks? This cycle repeats. Scores 59. $200 What is a collision of two continental plates Scores 60. $400 This is the only country that has a divergent boundary running down the middle 62. $600 This is why there is no subduction at continental-continental collisions 63. $600 What is both plates are of very similar density? Scores 64. $800 The name for the earthquake and volcano zone that encircles the Pacific Ocean 66. $1000 This mountain chain is believed to have been formed when the North American plate converged with another continental plate during the formation of Pangaea.
