Changing magnitude of stores of water Flashcards
Evaporation
Change from liquid water to gas (water vapour)
Evaporation occur?
Energy from solar radiation hits surface of water or land and causes the change in state
Condensation
Gas to liquid as a result of cooling
Causes of precipitation
Condensation is the direct cause of precipitation
Takes place when volume of air increases
Relief rainfall
Prevailing wind picks up moisture from sea
Moist air is forced to rise over mountain, cools and condenses forming clouds
Air drops increasing amount of water it can hold
Convectional rainfall
Surface of the earth is heated
The warm surface heats the air and this rises
Convection produces culuniombus clouds which create rain
Frontall rainfall
Warm and cool air are blown towards each other
Warmer air is forced to rise over denser cold air
Produces a variety of clouds
Cryospheric processes
Processes that affect the total mass of ice at any scale
Act when the temperature gets close to freezing point or below
Accumulation
Build up of ice mass, inputs exceed outputs
Ablation
Loss of ice mass
