46. Water is added to the earth's oceans by:
First the water goes through a never-ending cycle of evaporation, condensation, and precipitation. Energy from sunlight causes molecules to evaporate from the surface of a body of water. These molecules become part of the air in the form of water vapor. As air rises in the atmosphere, it cools. The loss of heat causes water vapor to condense into tiny water droplets or ice crystals, forming clouds. If the droplets or crystals grow and become heavy enough, they fall as precipitation that can come in the form of rain, snow, sleet, or hail. Precipitation falls on mountains, melts, and runs into lakes and rivers, which leads to the oceans.
Summarized Process:
1.Water evaporates from bodies of water
2.Water vapor condenses to form clouds
3.Water falls to earth's surface as precipitation
