| Hint | Answer | % Correct |
|---|---|---|
| The conversion of water to vapour | Evaporation | 70%
|
| The combined effect of evaporation and transpiration | Evapotranspiration | 60%
|
| The only open system in the water cycle where local factors control the throughput of water through a local store. | Drainage Basin | 55%
|
| Water entering the top soil | Infiltration | 55%
|
| Water is taken up by plants and is formed onto the leaf surface | Transpiration | 55%
|
| When gaseous water transforms to liquid state | Condensation | 50%
|
| A situation where pressure systems and weather patterns reverse in the Southern hemisphere | El Nino | 50%
|
| Temporary storage as water is captured by plants, buildings and hard surfaces before reaching the soil | Interception | 50%
|
| The downward seepage of water through rock under gravity | Percolation | 50%
|
| Release of water in liquid state | Precipitation | 45%
|
| Flow of water over the surface when the ground is saturated, frozen or impermeable | Surface runoff | 45%
|
| Water availability falls below 1000m³ per person | Water Scarcity | 45%
|
| When cold air meets a weather front, warm air rises above cold air which then cools and condenses, falling as rain. (Rainfall) | Frontal | 40%
|
| Air is forced upwards due to the relief of an area. This air cools and condenses, falling as rain. (Rainfall) | Orographic | 35%
|
| The store of water in gas state (store) | Atmospheric | 30%
|
| Thermal energy from the sun causes air to rise into the atmosphere. This cools, condenses and falls as rain (Rainfall) | Convectional | 30%
|
| The store of water in solid state (store) | Cryospheric | 30%
|
| When 'normal' pressure systems and weather patterns intensify | La Nina | 30%
|
| The flow of hot and cold water around the oceans | Thermohaline Circulation | 30%
|
| The summation of all water in the seas and oceans (store) | Oceanic | 25%
|
| The amount of water that could be evaporated and/or transpired from an area if there was sufficient water available | Potential Evapotranspiration | 25%
|
| Precipitation (P) = Streamflow (Q) +Evapotranspiration (E) Changes in storage (S) | Water Balance | 25%
|
| Where larger rivers cross several different relief and climate zones (river regime) | Complex | 20%
|
| The amount of precipitation remaining after evapotranspiration | Effective Rainfall | 20%
|
| Where a river experiences a period of seasonally high discharge followed by low discharge (river regime) | Simple | 20%
|
| The hidden flow of water when food or other commodities are traded | Virtual Water | 20%
|
| The amount of water usually available within a particular region | Base flow | 15%
|
| The summation of all water on the land surface and in the subsurface (store) | Terrestrial | 15%
|
| Consumption exceeds 10% of its renewable freshwater supply | Water Stress | 15%
|
| Ways in which water accelerates under gravity | Gravitational Potential Energy | 10%
