Transcript

  • 1. The Hydrologic Cycle – Grade 11
  • 2.  The water cycle, is the continuous movement of water on, above and below the surface of the Earth. Water can change states among liquid, vapor, and ice at various places in the water cycle.
  • 3.  The water moves from river to ocean, or from the ocean to the atmosphere, by the processes of evaporation, condensa tion, precipitation, inf iltration, runoff, and subsurface flow.
  • 4.  Precipitation occurs as rain, snow, hail, fog drip, graupel, and sleet. Infiltration is the flow of water from the ground surface into the ground. Once infiltrated, the water becomes soil moisture or groundwater.
  • 5. The variety of ways bywhich water moves acrossthe land, includes bothsurface runoff and channelrunoff. As it flows, thewater seep into the ground,evaporate into the air,become stored or beextracted for agricultural orother human uses.
  • 6.  Water turns from a liquid to a gas as the water moves through the air. The source of energy for evaporation is solar radiation. Evaporation is also transpiration from plants.
  • 7.  The change from solid water (snow or ice) to water vapor. Advection is the movement of water — in solid, liquid, or vapor states — through the atmosphere.
  • 8.  Water vapor turns to liquid water droplets in the air, creating clouds and fog. Transpiration is the release of water vapor from plants and soil into the air. Water vapor is a gas that cannot be seen.
