there are many different routes that a molecule of water might take in the hydrologic cycle. Imagine one molecule's journey. It begins as a drop of warm ocean water that evaporates. Air currents transport the vapor into the atmosphere. As temperatures cool high above the earth, the H2O molecules condense and create clouds.
Finally,when the drops of water become weighty enough, they fall as precipitation,rain. If the rain contacts land, it might soak into the ground, it might be absorbed by thirsty grass and shrubs. if precipitation from clouds falls in extremely cold climates, H2o is likely to fall as beautiful snow
