Hydrological Cycle

• Infiltration


  Process by which water enters the ground or soil.
• Precipitation


  Water falls from clouds towards the ground, as rain or snow, if the air is cold enough.
• Condensation


  Warm moist air cools as it rises, water vapour changes into water droplets. Small droplets may combine and gather to form larger droplets and clouds.
• Surface Runoff


  Water flows from highlands and over the ground surface into streams and rivers.
• Transpiration


  Process by which water is lost through the surface of a plant (via leaves.)
• Evaporation


  Sun's heat cause water to change into water vapour.
• Percolation


  Downward flow of water through soil, into the ground water due to gravity.
• Groundwater


  Water that collects below the surface of Earth.
