or:Water in its solid state, produced by freezing. As the water in lakes and seas cools, it becomes heavier. The lighter, warmer water is displaced by the heavier water and rises to the top. But when the water as a whole reaches about 4\u00b0 C. (39\u00b0 F.), this process reverses. The water becomes lighter as it nears the freezing point and remains as a layer above the warmer water beneath. This upper layer then turns to ice, \u201cmakes itself compact.\u201d Being lighter than water, the ice keeps the waters beneath \u201chidden as by stone,\u201d protecting marine life. Were it not for this phenomenon, much of the water in the lakes and even the oceans would in time become solid ice, making the earth inhospitable to life.Jehovah God called Job\u2019s attention to the marvel of ice, the Almighty saying: \u201cOut of whose belly does the ice actually come forth\u00a0.\u00a0.\u00a0.\u00a0? The very waters keep themselves hidden as by stone, and the surface of the watery deep makes itself compact.\u201d (Job 36:1; 37:10; 38:1, 29,\u00a030) The formation of ice as here referred to is possible only because of a most unusual property of water. As mentioned above we can understand as the water in lakes and seas cools, it becomes heavier.For more information on this subject and others, please go to jw.org \"Online Library.\" Also for free downloads, publications or read online.
