When the crest of a wave meets the trough of another wave, the amplitude of the overlapping waves is smaller than either of the two original waves. How do you think this affects the amount of energy traveling through each wave? Explain your reasoning. (Hint: Consider what happens to each wave after they meet and overlap.)

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is
