The phrase
"hydrologic cycle" refers to the continuous movement of water on Earth. It begins with water evaporating from bodies of water, such as lakes and oceans, and turning into vapor. The vapor then rises into the atmosphere, where it cools down and condenses into clouds. Eventually, the condensed water droplets become heavy and fall back to the ground as precipitation, like rain or snow. This water then flows into rivers, streams, and groundwater, which eventually makes its way back to lakes and oceans, starting the cycle again.
