住在海边的人，大概都欣赏过潮汐雄伟壮观的景象。但是，你知道潮汐是怎样形成的吗？
我们知道，月亮和地球相互吸引，月亮仿佛是个巨大的“吸铁石”吸引着地球上的海水，不停地把海水吸向月亮的方向。同时，由于地球的不断自转，海水又受到离心力的作用。对着月亮一边的海水，离月亮较近，受到的吸引力比离心力小，因此就鼓向月亮；背着月亮的海水，受到的吸引力比离心力小；中间部分便凹陷下去。这样，海面就形成了鸡蛋壳那样的椭圆形。随着地球的自转，海面各处的高不断改变，于是潮汐便形成了。
由于海底深浅不一，海岸又高低不平，这就使各地潮汐出现了差异。我国黄海、东海沿岸，一天涨落一次，称为全日潮。南海沿岸。多数地方有时涨落两次，也有时一天涨落一次，称为混合潮。又因为浅海和沿岸的潮水是从近的大洋里传过来的，所以在水浅、狭窄的海域潮汐幅度就比较大，例如渤海沿岸和黄海西岸一般有三四米左右，黄海东岸则高达八至十米。而且宽阔的海域，潮汐幅度就比较小。比如南海潮汐，多数在三米以下。
潮汐的`出现是有规律可循的。我国沿海人民，在长期的生活实践中，创造了一种计算半日潮出现时间的简便办法，并把它编成了顺口溜“阳历日期记在心，减一再乘五分；加上初一高潮时，潮汐涨落便分明。”比如，你观测到某地每逢初一半夜两点钟潮水涨得很高，如果你想知道初七的潮汐的时间，就用7减去1得6再把6乘以50分，得300，相当于5个小时，再加上初一高潮的两点钟，得到的是早上七点，这便是某地初七发生高潮的时间了。不过，利用这个方法就算下半月潮汐的时间，就要把减1改为减15了。
潮汐的涨落，蕴藏着巨大的能量，人们已经可以利用潮汐来推动电机，使它化为能量。据说，我国沿海的潮如果能被充分利用每年可以发电2750亿度。这是一笔多么大的资源啊。随着科学的日益发达，潮汐的涨落必将给人们带来更多的好处。
