Plate Tectonics Test Review What is the name of the SUPERCONTINENT that was once one land mass? Pangaea Wegener proposed a THEORY about the continents. He said they have been moving around for millions of years. What did he call this THEORY? The theory of Continental Drift Untold tragedies of Continental Drift.. Name the 3 types of heat transfer. Here are some hints Types of Heat Transfer: Geologists learn about the interior of Earth by studying ___. A.Land formations B.Seismic waves C.Weather patterns Seismic Waves What causes the mantle rock to flow very slowly? Convection Currents What is the type of heat transfer where a metal spoon heats up if its left in a hot pot of soup? Conduction Multiple Choice: The ______ heats the mantle and makes the convection currents move. A. sun B. core C. geothermal activity B. core True or False? If convection currents stopped moving it would mean that the inner core is no longer heating the mantle. TRUE! The heat from the core heats the mantle. The movement in the mantle make the plates of the lithosphere move slowly. Which ocean would you cross if you left the eastern coast of North America and travelled to Europe? A. Atlantic B. Pacific C. Indian D. Southern A. Atlantic Which ocean is just north of Antarctica? A.Atlantic B. Pacific C. Arctic D. Southern Over which ocean would you travel if you left northern Canada and went towards the North Pole? A. Atlantic B. Indian C. Arctic D. Southern C. Arctic Why does mantle rock begin to sink back towards the lower mantle from the area closest to the crust? A.The mantle rock is floating. B.The mantle rock is cooled near the crust, becoming more dense. C. The mantle rock is warmed near the crust, becoming less dense. D. The mantle rock does not change near the crust. B. The mantle rock is cooled near the crust, becoming more dense. Wegener used evidence to explain plate movement. Which of the following was evidence used in his research? A. Land features B. Fossil evidence C. Climate evidence D. All of the above Heat transfers through space. An example of this type of heat transfer is feeling the warmth of the sun on your face when standing outside. Which type of heat transfer is this? A. Radiation B. Conduction C. Convection D. Compaction A. Radiation Heat transfers by movement of currents in liquids and gasses. This is caused by differences in temperature and density. An example of this type of heat transfer occurs when mantle rock moves from near the core, towards the crust, and back again. A. Radiation B. Conduction C. Convection D. Compaction C. Convection Harry Hess was an American geologist who found evidence to support Wegeners theory. His research showed that new rock formed on the ocean floor at the mid-ocean ridge while older rock was moved farther from this crack in the oceanic crust. What was this process called? A. Continental drift B. Sea-floor spreading C. Law of superposition D. Law of supervision B. Sea-floor spreading An area that surrounds the Pacific Ocean where many volcanoes are located is called the ___. A. Mid-ocean ridge B. Subduction zone C. Ring of Fire D. Hotspot C. Ring of Fire Fossils of a tropical fern found in Antarctica shows evidence that ___. A. Antarctica was once located in a warm area closer to the equator B. Ferns grow in cool climates C. Fossils cannot tell us anything about climate D. Sid the sloth picked the ferns for Granny and took them with him on his journey A. Antarctica was once located in a warm area closer to the equator Mountain ranges that match up on the continents of South America and Africa show which type of evidence used by Wegener? A. Land features B. Fossil evidence C. Climate evidence D. Not evidence used by Wegener A. Land features
