• evaporation 


  water is heated and turns into a gas called water vapour
• condensation

• precipitation

• interception


  when leaves and plants catch raindrops
• infiltration


  when water soaks into the soil
• groundwater 


  water that is stored underground within rocks
• transpiration 


  when trees and plants let water vapour back into the sky from their leaves
• permeable rock


  lets water through
• impermeable rock

• water cycle 


  the never ending movement of water from sea to sky to land and then back to the sea
• surface runoff


  when water hits the land and flows over the surface into a river
• abstraction

• water footprint
