1 Name: Date: 1. Which human activity does NOT help control water runoff? A. contour plowing B. planting crops C. building flood control dams D. paving with asphalt 2. Which is NOT an effect of sewage put into the ocean? A. growth of bacteria B. growth of algae C. growth of coral D. death of marine life 3. Today, oceanographers map the ocean floor using sonar techniques. These techniques were adapted from the original sonar systems developed for A. divers. B. locating fish. C. submarine detection. D. communicating with dolphins. 4. When industrial waste enters rivers, it eventually reaches the ocean. This pollution can kill ocean life or make seafood unsafe for eating. Which is NOT true about this type of pollution? A. It is spread in the ocean by currents. B. It is sometimes radioactive. C. It is often concentrated in coastal areas. D. It is all being eliminated by modern technology. 5. When an area of Earth's surface suddenly moves, a seismograph draws wavy lines. Which of the following MOST LIKELY happened? A. a volcanic eruption B. a thunderstorm C. a nuclear explosion D. an earthquake 6. What instrument does a geologist use to record the motions produced by an earthquake? A. a seismograph B. an anemometer C. a spectrograph D. an optometer 7. Which solution helps to control floods? A. using contour plowing B. building bridges over rivers that flood C. building control dams and levees D. creating deltas at the end of rivers that flood 1

2 8. In many places, sand is being pumped from the sea floor onto the beaches. Why is there a need to put sand on beaches? A. The sand on the beaches wears out. B. Wave action causes erosion of the sand. C. Too much sand is piled into sand dunes. D. Old, dirty sand has to be replaced. 9. Which is a device that is used to gather information about formations on the ocean bottom? A. sonar B. radar C. MRI D. laser 10. Technology can help to control the natural force of A. volcanoes. B. water. C. earthquakes. D. plate tectonics. 11. A river flows past several small towns. It has been decided that a dam will be built on the river. How will the dam benefit the towns along the river? A. It will allow the towns to control flooding along the river. B. It will increase the fish population along the river. C. Water will be available for home heating. D. Water in the river will be much cleaner from the dam. 12. In many farm areas, slightly hilly farmland is plowed in curves rather than straight lines. This kind of plowing is called "contour plowing." Why is this type of plowing done? A. to prevent loss of topsoil B. to make crops more attractive C. to increase safety during harvest D. to reduce the number of insect pests in crops 13. Several dams were built across the Chattahoochee River. Which is one of the reasons they were built? A. to prevent runoff B. to prevent flooding downstream C. to increase the flow of water in the river D. to decrease the amount of water upstream 14. Which of these is a result of human intervention on destructive processes? A. the building of Hoover Dam B. initiation of satellite system relay C. the flooding of the Mississippi Delta D. construction of the Empire State building Earth Science S5E1c (EarthScienceS5E1c) 2

3 15. How could human interaction decrease the destructive force of hurricanes on coastal areas? A. create levees to control water flow B. research the impact of organisms in the Mississippi Delta region C. study storm drain management in the South American rain forests D. assess the effects of seismological activity on metropolitan areas 16. Which of these statements explains the use of technology to prevent earthquake damage? A. study the impact of organisms on fault lines B. to build dams and levees along floodplains C. reclaim coastal beaches in earthquake prone areas D. the invention of seismology tools to predict earthquakes 17. Which human intervention should be used in an area prone to flooding? A. digging wells to hold excess water B. building deltas to hold back flood waters C. storm drain management to redirect water D. studies to monitor the effects of volcanoes on flooding 18. Which is a way local residents can help preserve coastal islands? A. encourage large-scale building projects that occupy coastal beaches B. encourage building barriers to stabilize the coastal islands C. discourage repeated surveying of the barrier islands D. discourage new species of animals from settling on coastal islands 19. A conservation group wants to control some of the destructive processes created by erosion in a costal area. Which action should the group take? A. place a series of mesh panels perpendicular to the beach B. build underwater walls 100 miles from the shore line C. introduce non-native plants and animals to the area D. restore a lighthouse to warn ships of the rocky coast line 20. Which is an example of a seismological study? A. comparing the North Atlantic current to currents in the Pacific B. evaluation of sample images of the Northwestern Pacific mantle C. researching the geological history of Antarctic plant life D. examination of surface features in tornado alley 3
