Drift Sea-Floor Spreading 100 100 100 100 200 200 200 200 300 300 300 300 400 400 400 400 500 500 500 500 Crust, core, mantle Name the layers of the Earth in order from thinnest to thickest Row 1, Col 1 Conduction, convection, radiation Name the 3 types of heat transfer 1,2 Granitic What type of rock make up the majority of continental crust? Which type of crust, oceanic or continental, is generally older? 1,3 Harry Hess, sonar What scientist helped to discover the process of sea-floor spreading? What type of technology was available to him that helped him prove his theory? DD 1,4 Basalt What is the main type of rock in oceanic crust? 2,1 molcules in the substance move apart and make it less dense How does the density of most Liquids and/or gases substances change when heated? Why? 2,2 More oceanic crust is subducting than is beingcreated at mid-ocean ridges The Pacific ocean is shrinking! Explain how this could be happening 2,3 OldesJuan de Fuca, Pacific, Eurasian, Afican Name 3 plates that interact with the North American plate 2,4 Very uppermost part of the mantle and crust What layer(s) of the Earth make up the lithosphere? Explain 3,1 Heat=less dense=rises=cools=increase density=cycle Describe how convection currents form in a lava lamp? 3,2 Matching coastlines, fossils/climate, land feature Name and explain 3 pieces of evidence that supported Wegener’s hypothesis 3,3 Divergent (C-C) What type of boundary formed Iceland? Name the 2 plates 3,4 Name 3 island arcs formed by the Ring of Fire 4,1 Heat from stove, heat from fire Besides from the sun, name 2 other examples of radiation 4,2 S. America,Africa Name two continents that lie on the equator 4,3 San Andreas Fault(T) / Cascades (C) /Mid-Atlantic Ridge(D) Name one actual place here on the N. American plate, formed by each type of plate boundary DD 4,4 Seismic waves, age of rock on ocean floor How do we know what the interior of the Earth is like? 5,1 Conduction from body heat, heat is radiating from heater Name 2 ways heat transfer is happening to you right now. 5,2 Could not explain what force pushed and/or pulled the continents Why was Wegener’s hypothesis rejected? 5,3 Mountains, valleys, trenches, islands, volcanoes Name one feature that occurs at each of the 3 plate boundaries 5,4
