Here is how Compton’s Encyclopedia describes what happens: “Water . . . evaporates from the surface of the oceans into the atmosphere . . . Steadily moving air currents in the earth’s atmosphere carry the moist air inland. When the air cools, the vapor condenses to form water droplets. These are seen most commonly as clouds. Often the droplets come together to form raindrops. If the atmosphere is cold enough, snowflakes form instead of raindrops. In either case, water that has traveled from an ocean hundreds or even thousands of miles away falls to the earth’s surface. There it gathers into streams or soaks into the ground and begins its journey back to the sea.”1
This remarkable process, which makes life on dry land possible, was well described about 3,000 years ago in simple, straightforward terms in the Bible: “All streams run into the sea, yet the sea never overflows; back to the place from which the streams ran they return to run again.”—Ecclesiastes 1:7
Jehovah tells Job to consider the clouds. (Job 38:34-38) Man cannot order a single cloud to appear and release its water. But how dependent humans are on the water cycle that the Creator has established!
What is the water cycle? One reference work states: “The water cycle consists of four distinct stages: storage, evaporation, precipitation, and runoff. Water may be stored temporarily in the ground; in oceans, lakes, and rivers; and in ice caps and glaciers. It evaporates from the earth’s surface, condenses in clouds, falls back to the earth as precipitation (rain or snow), and eventually either runs into the seas or reevaporates into the atmosphere. Almost all the water on the earth has passed through the water cycle countless times.”—Microsoft Encarta Reference Library 2005.
