The document summarizes the water cycle in 5 steps: 1) Water is evaporated from sources like oceans by the sun's heat and rises into the air as vapor. 2) In the cool atmosphere, the vapor condenses to form clouds. 3) The clouds become heavy and water falls back to earth as precipitation like rain or snow. 4) Precipitation seeps into the ground or flows over land into rivers and streams and eventually oceans, completing the cycle. 5) The sun then evaporates water from the oceans again to repeat the cycle, which has continued for over a million years and is essential for all life on earth.
