Tides arc created mainly by the pull of the moon on the earth. The moon’s pull causes water in the oceans to be a little deeper at a point closest to the moon and also at a point farthest from the moon on the opposite side of the earth. These two tidal "waves" follow the apparent movement of the moon around the earth and strike nearly every coast line at interval of about twelve hours and twenty-five minutes. After reaching a high point, the water level goes down gradually for a little more than six hours and then to rise toward a new high point. Hence, most coast lines have two tides a day, and the tides occur fifty minutes late each day. Differences in the coast line and in channels in the ocean bottom may change the times that the tidal wave reaches different points along the stone coast line. The difference in water level between high and low tide varies from day to day according to the relative positions of the sun and the moon because the sun also exerts a pull on the earth, although it is only about half as strong as the pull of the moon. When the sun and the moon are pulling along the same line, the tides rise higher, and when they pull at right angles to one another, the tide is lower. The formation of the coast line and variations in the weather are additional factors which can affect the height of tides. Some sections of the coast are shaped in such a way as to cause much higher tides than are experienced in other areas. A strong wind blowing toward the shore may also cause tides to be higher. [br] What may be concluded from the information presented in the passage about time of tide along different coast lines?
选项
答案
Some coast lines do not have two tides each day./Not all coast lines have two tides each day
解析
该题问的是关于在不同的海岸线上,潮汐上涨的次数问题,在文章中间部分已提到了“Hence, most coast lines have two tides a day, and the tides occur fifty minutes...”意思是说“大部分海岸线上一天有两次涨潮,且每天延迟五十分钟”,从这一句话中我们不难推断出,有的海岸线每天没有两次潮汐
