    Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. Precipitation is the main way atmospheric water returns to the surface of the Earth. Most precipitation falls as rain.

    Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.

  4. Water cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. The total amount of water remains essentially constant.

  5. The Water Cycle | Precipitation Education

    gpm.nasa.gov/education/water-cycle

    The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.

  6. The water cycle is what moves Earth’s water around the planet to places where plants, animals and humans can use it. Precipitation is one of four main parts of the water cycle. Evaporation: Liquid turns to gas. Transpiration: Water from plants turns to gas.

    Precipitation results when tiny condensation particles, through collision and coalescence, grow too large for the rising air to support, and thus fall to the Earth. Precipitation can be in the form of rain, hail, snow, or sleet. Precipitation is the primary way we receive fresh water on Earth.

  8. Water cycle - National Oceanic and Atmospheric Administration

    www.noaa.gov/.../resource-collections/freshwater/water-cycle

    The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

  9. Water Goes Down. Water cycle steps on the Earth’s crust are highly dependent on the type of ecosystem. These steps are water condensation, precipitation, and deposition. Water does not fall to earth in the form of water vapor. As water vapor rises, it loses heat energy through continuous motion.

  10. Hydrology Education: The Water Cycle - National Weather Service

    www.weather.gov/lot/hydrology_education_watercycle

    Precipitation is water that falls from the atmosphere to the Earths surface. Infiltration is precipitation that soaks into the soil. Runoff is precipitation that does not soak into the soil but instead moves on the Earth’s surface toward streams.

    Precipitation is a major component of the planet’s water cycle, and is the source of most of its fresh water. It occurs when water vapor levels in the atmosphere reach saturation upon which water vapor condenses or deposits on small particles called condensation/ice nuclei to form clouds consisting of suspended liquid or ice particles or a ...
