D 10.D 11.B 12.4 SOL REVIEW….PLATE TECTONICS Read each fact carefully and then be prepared to answer the questions that follow NO TALKING HIGHLIGHT WHAT YOU DO NOT KNOW HERE WE GO Oceanic Crust…thin, young & dense…sinks Plate Tectonics Continental Crust… thick, old & less dense…floats Volcano & Earthquake locations were used to establish plate boundaries 3 Types of Plate Movement or Boundaries: CONVERGENT DIVERGENT OLDEST Crust YOUNGEST Crust Sea Floor being destroyed here Sea Floor being created here TRANSFORM Ex. San Andreas Fault Key words for each plate boundary include: collision,→←, pulling apart,←→, sliding past each crashing, sea floor spreading other,↑↓, strikesubduction zone newest sea floor slip, earthquakes Features created at each boundary include: Mountains, Mid-ocean ridges, Hawaiian Islands were not Volcanoes, Trenches, Rift valleys & created by plate movement Pangaea…one landmass Volcanoes but by HOT SPOTS Plate Tectonics & Earthquakes 3 seismograph stations are Earthquakes occur when there is movement along a fault (crack) needed to find the epicenter Plate motion occurs as a result of convection in Earth’s mantle. Plate movement is driven by convection currents in the mantle. Hot rises, cold sinks Epicenter Earthquake & Volcanic activity is associated with all plate boundaries Earthquake Info: Ring of Fire: surrounds the P-Waves Arrive 1st & travel through solids and liquids Pacific Ocean Plate…high area of nd S-Waves arrive 2 & travel through earthquake/volcano activity solids only…inner core of Earth is solid Outer Core is Liquid Epicenter (911) happens on the surface of the earth Focus happens deep inside the earth… Can you answer the following questions? Which is the best evidence of crustal movement? Molten rock in the Earth’s outer core Titled rock layers Wheresedimentary are earthquakes most likely to take place? Marine fossils found below sea level Along the core-mantle Glacial striations found boundary on bedrock Which location is be closest to Where the composition of the Earth tends to uniform Near the Earth’s Equator the earthquake epicenter? Near a fault zone D A C B Where is the thickest part of the Earth’s crust? At the edge of continental shelves At mid-oceanic ridges The igneous material along mid-oceanic ridges is found continental ranges toUnder be younger than mountain the igneous material from the ridge. Under This factvolcanic supportsislands the theory of Superposition Continental Drift Seafloor spreading Cross cutting Can you answer the following questions? Which location best represents plate movement along a diverging boundary? A B C D Which diagram represents plate movement associated with transform faults such as those causing California earthquakes? AWhichB diagram C shows D a subduction zone? A B C represents D Which diagram 2 continental plates converging? A B C D Can you answer the following questions? Movement of the crustal plates shown in the diagram is most likely caused by The revolution of the Earth The erosion of the Earth’s crust The crust at the midShifting of the Earth’s ocean ridges is composed magnetic poles mainly of Convection currents in the shale Mid-ocean limestone ridges such as Earth’s mantle East Pacificbasalt Rise and the granite Oceanic Ridge are best Mountains containing folded described as sedimentary rocks Sections of the ocean Moutains containing fossils of floor that contain the present day marine life youngest oceanic crust Can you answer the following questions? Which seismogram was recorded at Tampa? A B C D How many seismograph stations are needed to find the epicenter of an earthquake? The 1 primary 2 3 cause 4 of convection currents in the Earth’s mantle is believed to be the Differences in densities of earth materials Rotation of the Earth Occurrence of earthquakes
