The Water Cycle

Discover the amazing journey of water as it cycles through the atmosphere, ocean, and land, driven by energy from the sun. Explore the different processes involved, such as evaporation, condensation, precipitation, and more. Learn about the importance of water storage in ice, snow, groundwater, and oceans, as well as its role in sustaining life on our planet.

  1. The Water Cycle

  2. Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet.

  3. Water Storage in Ice & Snow • Includes ice caps, glaciers, and permanent snow

  4. B. Precipitation • Rain, snow, sleet, hail, etc. • Under correct temperature and atmospheric pressure, small water droplets in clouds become larger and precipitation

  5. C. Snowmelt runoff to streams

  6. D. Infiltration • Some precipitation soaks into ground. As it filters through soil and rock layers, it becomes cleaner (impurities are filtered out)

  7. E. Groundwater Discharge • Some ground water returns to the surface either through the roots of plants or wells dug by humans

  8. F. Ground Water Storage • Water stored underground

  9. G. Water Storage in Oceans • 97% of the water on earth is stored in oceans

  10. H. Evaporation • Liquid water turns into water vapor in the atmosphere • High temperature & low air pressure make this happen

  11. I. Condensation • Water turns from vapor to liquid (opposite of evaporation) • Lower temperatures favor condensation

  12. J. Water Storage • In the form of clouds and fog, water can be stored in the atmosphere

  13. K. Evapotranspiration • Plants absorb water from the soil, move it through their roots and stem to the leaves. • Water is released through the leaves into the atmosphere.

  14. L. Sublimation • Water turns directly from a solid to a gas (snow or ice to water vapor)

  15. M. Surface Runoff • Water normally flows downhill unless a force other than gravity is acting upon

  16. N. Streamflow • Streams and rivers flow downhill.

  17. O. Spring • Places where freshwater is released from underground.

  18. P. Freshwater Storage • Ponds, rivers, streams
