  1. 6th Grade Science Mrs. Bright (6-4.2) The Water (H2O) Cycle

  2. 6-4.2 & 6-4.5 • 6-4.2 Summarize the interrelationships among the dynamic processes of the water cycle (including precipitation, evaporation, transpiration, condensation, surface-water flow and groundwater flow). • 6-4.5 Use appropriate instruments and tools to collect weather data. (rain gauge)

  3. Water Cycle Animation • 1. Water is always moving between the troposphere and surface of Earth. • http://www.epa.gov/ogwdw/kids/flash/flash_watercycle.html

  5. Each component of the water cycle process has certain conditions under which each form of precipitation develops:

  6. The Sun 2.The sun’s energy is necessary to power the water cycle.

  7. The water cycle begins with WATER! 3. SOLID: ice, frost, hail, snow LIQUID: ocean, cloud, rivers, puddles, rain, dew GAS: water vapor

  8. 4. EVAPORATION ●The sun warms the water causing it to change fromwater (liquid) to water vapor (gas) by a process known as evaporation. ●Water that evaporates enters the Earth’s troposphere.

  9. 5. TRANSPIRATION • Plantsrelease water vapor into the air also. This process is called transpiration.

  10. Transpiration: when plants change water from a liquid to gas. Can a plant turn liquid water into water vapor? YES

  11. 6. CONDENSATION ● Condensation happens in the atmosphere as water vapor cools and changes to water droplets. ● Condensation forms clouds, dew, or frost.

  12. Condensation

  13. Condensation: When water turns from water vapor back into a liquid (clouds or dew) or sometimes a solid (frost).

  14. 7. DEW • Dew forms when the water vaporCONDENSES directly onto asurface.

  15. 8. FROST • Frost forms when water vapor CONDENSES from a gasdirectly toice crystals. • This happens when the temperature is at the freezingpoint or below.

  16. 9. PRECIPITATION ● After condensation occurs (forming clouds), water droplets fall in various forms of precipitation. ● Temperaturevariations within the clouds and /or within the region between the cloud and Earth allows for the different forms of precipitation.

  17. 10. Forms of Precipitation • RAIN: falls when air is warm (above freezing) • SNOW: falls when air is so cold that water vapor changes directly to a solid. • SLEET: when raindrops pass through a layer of freezing air near Earth’s surface, forming ice pellets. • HAIL: are pellets of ice that form inside a cloud when water freezes in layers around a small nucleus of ice.

  21. Precipitation collects in: • Rivers • Lakes • Oceans • Streams • Ponds • Puddles

  22. 11. How do we measure precipitation? • Precipitation is measured with a rain gauge in inches or centimeters.

  23. 12. Run-Off ● If precipitation falls on land surfaces, it always attempts to move back toward sea level as surface-water flow or groundwater flow.

  24. 13. Surface-water Flow • SURFACE WATER FLOW is the flowing of water over theland from higher to lower ground. • Water will remain on the surface when the surface is not porous or the precipitation is falling too fastfor the water to sink into the ground.

  25. 14. Ground Water flow • GROUND WATER FLOW is the flow of water underground. • Water will sink into the ground when the surface is porous and there is lots of space in the soil to hold the water.

  26. Groundwater flow (runoff): ________________________ the flow of water underground. Porous vs. Non-porous ground.

  28. Then what? Right! It starts all over again! That is why it is called a cycle.

  29. SUMMARY The sun warms ocean water causing it to EVAPORATE. Water vapor CONDENSES to form clouds. Clouds become very heavy before beginning to PRECIPITATE. Precipitation collects in rivers, lakes, and oceans. The sun warms ocean water…

  30. Evaporation, transpiration, condensation, precipitation.

  31. WATER CHANGES FORM • Evaporation: from a liquid to a gas • Condensation: from a gas to a liquid • Transpiration: plants change liquid to gas. • Precipitation: from a gas to a liquid or solid • Surface water flow (run off):the flowing of water over the land from higher to lower ground • Groundwater flow (run off) the flow of water underground.
