Tides are 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 intervals 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 begins to rise toward a new high point. Hence, most coast lines have two tides a day, and the tides occur fifty minutes later each day. Differences in the coast line and in channels in the ocean bottom may change the time that the tidal wave reaches different points along the same 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. The sun also exerts a pull on the earth, although it is only about haft as strong as the pull of the tides arise 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 the higher.
The time that high tide occurs at a particular place is affected by all of the following EXCEPT______.
选项
A、the direction of the wind
B、channels in the sea bottom
C、variations in the coast line
D、the position of the moon
答案
A
解析
见最后一句话:may also cause tides to the higher。
