Dr. hakoda is studying tsunamis—large waves that can reach heights of 1,700 feet. tsunamis are often caused when large chunks of ocean floor displace vast amounts of water deep in the ocean during an earthquake. the energy of this motion travels through the water as a wave, gaining height as it approaches land. when tsunamis occur, they often cause severe property damage, flooding, and death. what is the least destructive and most cost-efficient way for dr. hakoda to study tsunamis? a. perform controlled experiments in wave pools b. wait for tsunamis to occur and examine video footage c. create life-sized tsunamis in remote locations d. model tsunamis with computer simulations

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
