While providing the sand necessary to physically protect the coastline from wave action, the constant movement of sand means that sandy beaches are not able to support much life. True False Headland erosion means that one would expect increased erosion in coves and bays. increased erosion on flat shaped coastlines. increased erosion on features protruding from the rest of the coastline. Which of the following would be considered a cyclical driver of sea-level change? Warming of the ocean basins. Melting of terrestrial glaciers. Tectonic changes, altering the relative position of coastal land areas. Astronomical tides. Only those hazards that threaten many people at the same time are considered serious coastal hazards. For this reason, rip current are dangerous but not a serious coastal hazard. True False Concerns for coastal erosion often results in coastal adjustments undertaken with a short-term focus on a limited area directly affected by the erosion process. True False As a wave approaches the coastline, it changes in what manner(s)? The approaching wave becomes more circular. The approaching wave becomes less steep. The approaching wave becomes steeper. The approaching wave's trough becomes deeper. The east coast of the U.S. is an example of a tectonically active coastline. True False The difference between an extratropical cyclone and a hurricane is just the latitude where the storm forms. True False A tropical cyclone requires warm water that is above 26 degrees C for its formation and development. True False A tropical storm might lose strength and disorganize as a result of traveling too far from warm tropical waters. traveling over a land areas. a reduction in the ability of the storm to vent heat upward with convection. All of the above With today's modern scientific instruments and monitoring satellites, it is no longer necessary to fly planes through tropical storms in order to gather data used to make forecasts. True False A tropical cyclone that forms in the Indian Ocean would be called a hurricane. typhoon. cyclone.
