• Water Distribution

  Oceans cover over 71% of the earths surface. Oceans and Seas contain 97% of earths water, 3% of earths water is fresh and 65% of the 3% of fresh water is in ice sheets.
• Percipitation

  Moisture that reaches the earths surface as rain snow or hail
• Surface Run-off

  Percipitation that flows over the grounds surface eventually finding its way into rivers
• Interception

  Percipitation that does not reach the earths surface due to being obstructed by trees or plants
• Infiltration

  • Percipitation soaks through into sub surface soil levels and moves into rock cracks or pore spaces
• Through Flow

  The slow horizontal movement of water through the ground
• Evaporation

  Water from bodes of water is changed from water dropplets to water vapour
• Transpiration

  Evaportation of water from plant leaves
• Condencation

  Water Vapour converted back into liquid form due to a deacrease with temperature with height
