This statement is clear and easy to follow. The reader is provided with a basic knowledge of the tide's origin. This is crucial for Carson to explain further the outcome of these responses.
Next, Carson is successful in getting her point across through the use of examples. She does this to show the reader the effects of tides on real life experiences. Carson supports the following fact:the nature of the tides at any particular place is a local matter, with astonishing differences occurring within a very short geographic distance? (599). Carson supports this statement with a summer trip, involving boating and swimming in Nantucket Island and being inconvenienced slightly due to a range of about a foot or two between high and low water. Carson then gives an example of another vacation spot in the same body of water that maintains a rise and fall of forty to fifty feet. Carson chooses to introduce a summer trip as her example because it's something that the general audience will be able to relate to. This keeps the readers interested, and therefore they can fully understand the information. Carson also gives examples to open the reader's view of tidal effects. Carson states that sea creatures adapt to the tides, andthe breathing rhythm of certain marine animals is times to coincide with the passes of the phases of the moon and the stages of the tide? (602). An example to support this fact is the lifestyle of the Palolo worm. This worms breeding rhythm is in sync with the stages of the tides. Twice each year during the neap tides, the worm breaks its body in half and sends the reproductive half to the surface to liberate the cells. After two consecutive days the amount of eggs liberated is so high that they discolor the sea. This example gives the reader a clear relationship between the tides and the worm. It is easy to comprehend exactly what goes on during their interaction. At the end when Carson explains the amount of liberated eggs being so great they discolor the sea, the reader is left with a better understanding that something that small can have a noticeable effect on the human eye.
