The answer is - wavelength.
As the wave approaches the shore and it reaches shallow waters it's characteristics start to change. When the wavelength is half of the water depth than the bottom of the wave starts to drag on the ocean floor. As it starts to do this the wave starts to slow down at it bottom as it approaches the beach but the upper part of the wave maintains its initial speed. Because of this the wave becomes longer. Once it reaches the shore it crashes on it and falls apart.
hello there
Andrea's point is probably the answer you're looking for, however, you should keep in mind that many (most?) environmental laws are driven more by politics than by the available data. Scientists do research on any number of topics (environmental or not) that have implications for our society. We (scientists) like to think that policy makers take our data and results into consideration when drafting legislation, but I would say that in my experience this rarely happens. For one, there have rarely been any federal legislators who understand science. Even the few physicians who've gone into politics seem largely to fail to understand very basic tenets of science, or at least they don't often demonstrate it with their political actions. Leaving environmental issues, for example, if politicians took science into account, there would be no discussion in any school district in the country about whether or not evolution should be taught in schools, as there are simply *NO* scientists who are qualified to have an opinion who would suggest it shouldn't. Environmental issues are not really any different.
hope that helped bye
The answer would be A. distribution of mineral deposits.
This is because the amount of minerals found in a particular region can affect the economy because of the possible exporting of that material.
