Life near the shore everywhere is affected by the tides, which come and go twice each day in a cycle of about twelve-and-a-half hours—just different enough from the daily cycle of the sun so that there can be no regular relationship between the shore being alternately wet and dry and alternately light and dark. The extent of the tides varies greatly, from as little as one foot in inland seas like the Mediterranean, to fifty feet or so in the Bay of Fundy in Nova Scotia. In some parts of the world, one of the two daily tides rises higher and falls lower than the other; and tides at the time of new moon and full moon are generally greater than at other times. The extent of the intertidal zone thus varies from day to day as well as from place to place.
The kinds of organisms living in the region between the tidal limits depend very much on whether the shore is rocky, sandy, or muddy. Rocky shores have the most obviously rich faunas (某地区所有的动物),because of the firm anchorage for both animals and plants, and because of the small pools left by the retreating seas. Sandy shores, especially when exposed to surf (as they usually are), have the fewest kinds of animals.
The smallest tides occur in______.
选项
A、bays
B、open seas
C、inland seas
D、deeper seas
答案
C
解析
文中第一段第二句说:“潮水规模的变化很大,从内陆海,如地中海的一英尺高的最小潮汐到新斯科夏半岛内芬兰湾的50英尺左右高的最大潮汐。”显然,最大的潮汐在芬兰湾,而最小的潮汐就在内陆海。
