结冰是指水在物体表面或气温较低的环境中凝结成冰。这个过程通常是由于水温降低到冰点（0°C）时发生的。当水冷却到冰点时，它会开始凝结成冰。随着水温的下降，冰的结构会变得更加坚固，最终形成一块固体。
下面是一些关于结冰的英文例句：
"The water in the birdbath had frozen overnight, forming a thick layer of ice on the surface." (鸟塘里的水在一夜之间结冰了，形成了一层厚厚的冰。)
"The temperature dropped below freezing, causing the pipes to ice up." (温度降到了冰点以下，导致管道结冰。)
"I had to scrape the ice off my car windshield before I could drive to work." (我必须把车挡风玻璃上的冰刮掉，才能开车去上班。)
"The ice rink was busy with people skating and playing hockey." (冰场上有很多人滑冰和打冰球。)
