1
Q
Mnemonic to remember processes driving change in water stores
A
PEC
Precipitation
Evaporation
Condensation
2
Q
Precipitation
A
Air reduced to dew point
Occurs when warm moist air passes an area of cold
3
Q
Evaporation
A
Solar radiation hits the surface of water
Causes water to change to gas
Rate of evaporation depends on: amount of solar energy availability of water air humidity air temp.
4
