Waves are beautiful to look at,but they can destroy (@@) ships at sea,as well as houses and
buildings near the shore.What causes waves?Most waves are caused by winds blowing over the surface of the water.The sun heats the earth,causing the air to rise and the winds to blow.The winds blow across the sea,pushing little waves into bigger and bigger ones.
The size of a wave depends on how strong the wind is,how long it blows,and how large the body ofwater is.In a small bay(海湾) big waves will never build up.But at sea the wind can build up giant,powerful waves.
A rule says that the height of a wave(in meters) will usually be no more than one-tenth of the wind'' sspeed(in kilometers).In other words,when the wind is blowing at 120 kilometers per hour,most waves will be about twelve meters.Of course,some waves may combine to form giant waves that are much higher.Li 1933 the United States Navy(海军) reported the largest measured wave in history.It rose in the Pacific Ocean to a height of thirty-four meters

海浪虽然看上去很美,但是它们同时也能摧毁海上的船只以及海边的房屋等建筑.到底是什么导致海浪的产生呢?大多数海浪都是由风波动海面造成的.阳光照射地球表面导致空气受热上升产生了风.风渐渐吹过海面,将每次产生的小小的波动越推越大.
海浪的大小取决于风力,风的时长和水面的大小.小海湾中永远不会产生大海浪.然而在海上,风却可以产生出巨大,有力的海浪.
有种说法就是海浪的高度(单位:米)通常将不会超过风速率的十分之一(单位:千米).换句话说,当风速达到120千米/小时,大多数海浪将在大约12米高.当然,有些海浪可以聚集起来产生更高更大的巨型海浪.1933年美国海军报道过历史上测量过最高的海浪.它在太平洋上升起了34米的海浪.
