Read the text and choose the best answer to each question below. Tsunamis, whose name derives from the Japanese expression for “high wave in a harbour”, are giant sea waves. These waves are quite different from storm surges (tăng). They are also referred to by the general public as tidal waves although they have nothing to do with tides.Scientists often refer to them as seismic (địachấn) sea waves, which is far more appropriate because they are often the result of undersea seismic activity. Tsunamis can be caused when the sea floor suddenly moves, during an underwater earthquake or volcano, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances, at speeds close to 700 kilometers per hour. In the open ocean, tsunami waves are not very high, often no more than one or two meters. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 meters. 16.

All of the following is true about tidal waves EXCEPT ........................... A. they are as another name for tsunamis. B. they are caused by sudden changes in high and low tides. C. this term is not used by the scientists. D. the name refer to the same phenomenon as seismic sea waves. 18. The word “them” in the passage refers to ........................................... A. tidal waves B. tsunamis C. storm surges D. sea waves 19. The word “shallow” in the passage mostly means .............................. A. not clear B. tidal C. coastal D. not deep 20.
