The hydrological cycle

• Evaporation


  The process where a liquid is changed into a gas
• Transpiration


  A biological process by whoch water is lost from a plant through the minute pores in the leaves
• Evapotranspiration


  The total amount of moisture removed by evaporation and transpiration from the land surface
• Condensation


  The change in the atmosphere when droplets of water vapour cool and change back into liquid water
• Precipitation


  Any form of natrually occuring moisture falling from the sky
• Overflow and run-off


  The total of all the water that flows over the surface of the river basin, mainly flowing away within rivers
• Infilltration and percolation


  As the water moves through and seeps down the soil it may continue to move deeper into the rocks and settle down the water table
• Throughflow and groundwater flow

  Water dripping off one leaf or plant to another then flowing slowly bellow the water table through permeable rock
