Plate boundaries The best evidence that two land areas were once connected is the discovery that both land masses A. are in the same stage of succession. B. have similar types of rocks and fossils. C. have the same climate. D. exist along the same line of longitude. have similar types of rocks and fossils. Scientists claim that the continents of South America and Africa were once a single landmass. All of the following observations support this claim except A. B. C. D. the mountains on these continents have similar rocks of the same age. similar fish live in the ocean off the coasts of these continents. these continents appear to fit together like a puzzle the same kinds of fossils have been found on these continents. similar fish live in the ocean off the coasts of these continents. Sea floor magnetic stripes on the Pacific sea floor tend to be wider than equivalent-age magnetic stripes on the Atlantic sea floor. This suggests that: A. the Pacific Ocean is older than the Atlantic Ocean. B. the Pacific Ocean is younger than the Atlantic Ocean C. spreading rates in the Atlantic Ocean are slower than in the Pacific Ocean. D. Spreading rates in the Pacific Ocean are slower than in the Atlantic Ocean. spreading rates in the Atlantic Ocean are slower than in the Pacific Ocean. All of the following help to drive plate tectonic movement except: A. convection in the Low Velocity Zone B. the weight of descending ocean plate in subduction zones C. mountain building at continent-continent collision zones D. cooling of new lithosphere along the slopes of sea floor ridges mountain building at continent-continent collision zones There are 12 major tectonic plates that make up the earth’s surface. There are 3 major types of plate boundaries, name 1. Convergent Divergent transform Compare the densities and thickness of oceanic and continental crust Oceanic – thinner, more dense Continental- thicker, less dense a). b). c). d). Which graph represents temperatures inside the earth? a). b). c). d). B – gets hotter as get closer to core Which is accurate based on surface features? 1- convection cells pulling ridge apart Which table best shows the relative densities of the crustal bedrock at locations A-D? 2! – B and C are oceanic crust (more dense), A and D or continental crust (less dense) The oldest rocks would have come from which sample site? 1 – farthest from ridge where originates What happens at convergent plate boundaries? Plates collide, come together Where would the hottest crustal temps be found? C! – where magma comes out! Which graph correctly shows relative age of bedrock? 4! – Shows B is older than C The probable source of the Earth's magnetic field is: A. plate motions B. sunspot activity C. convection in the outer core D. sea-floor magnetic reversals The probable source of the Earth's magnetic field is: A. plate motions B. sunspot activity C. convection in the outer core D. sea-floor magnetic reversals Make your wager 1. List three pieces of evidence of plate tectonics 2. List two surface features we see on Earth as a result Evidence • Paleomagnetism • Sea floor spreading • Fossil evidence • Continents fit like puzzle • climate Changes in earth’s features • Volcanoes • Mountains • Earthquakes • Tsunamis • Trenches
