The Global Water Cycle The energy of the sun constantly transforms the water from solid (ice) to liquid (water) to gaseous (vapour) Constant transformation puts the water into motion and hence activates the global water cycle Characteristics of the cycle:  Permanent circulation  Renewable resource Source: OWENS (2006)

(PIDWIRNY 2006) 2.5% is freshwater whereas a fifth is easily accessible for human use. (INFORESOURCES FOCUS 2006)  only 0.5% of global water resources are usable 7 3.
