Poulsen IB ESS Topic 4

the time taken for a water molecule to enter and leave part of the hydrological system

• advection

• evaporation

• hydrological cycle

• turnover time

horizontal movement of water in the atmosphere, in vapor, liquid or solid states in air masses -- that is, wind-blown movement

• advection

• turnover time

• evaporation

• hydrological cycle

the sum of evaporation, sublimation and transpiration from land and ocean surfaces to the atmosphere

• advection

• condensation

• precipitation

• evapotranspiration

the proportion of total precipitation absorbed by soil and plants, then released back into the air

• green water

• blue water

proportion of precipitation that collects in water courses (in river, lakes, wetlands and as groundwater) and is available for human consumption

• green water

• blue water

passage of water into the soil

• transpiration

• percolation

• infiltration

• precipitation

downward vertical movement of water within a soil or rock

• infiltration

• percolation

• transpiration

• sublimation

select the options below that deforested areas often experience

• increased surface runoff

• reduced infiltration

• decreased soil erosion

• lesser flood risk

a graph showing the rate of flow (discharge) over a certain period past a specific point in a river (cubic meters per second)

• climatograph

• hydrograph

• epigraph

• paragraph

a flood caused by heavy or excessive rainfall in a short period, generally less than 6 hours

• flash flood

• steep flood

• crash flood

• urbanization
