Water cycle

• Water and oxygen cycles are available for re-use over and over again
• Condensation


  The change of water from gaseous into liquid form
• Precipitation


  Water moves from the atmosphere to earth in the form of rain, mist, hail, dew, and snow
• Infiltration


  Water infiltrates deep into the soil and comes to rest on solid rock formation to create the water-table
• Evaporation


  The process of turning from liquid into vapor
• Transpiration


  Loss of water vapor through the stomata of the leaves
• Atmosphere


  The air surrounding the earth's surface
• Respiration


  The chemical process whereby energy-rich molecules, example, glucose, is chemically broken down to release energy
• Photosynthesis


  The process whereby plants absorb CO2 and in turn release O2 in the atmosphere as a by-product
• Combustion


  Reaction of a substance with oxygen as in burning
• Evaporation occurs when heat from the sun causes water to change into vapor (gas) and rise up into the air as water vapor or steam.
• Evaporation occurs when heat energy causes water molecules to break free from their bonds with other substances (such as soil) and rise into the air.
• Transpiration refers to the process by which plants release water through their leaves as part of photosynthesis.
• Condensation happens when water droplets form around tiny particles like dust and pollen in the sky.
• The water cycle is the continuous movement of water between the Earth's surface, atmosphere, and oceans.
