Clues

  • Floodplains are valley floors that get covered in water when a river exceeds bankfull discharge. Marshes occur when the floodplain is saturated for a long time. (18)
  • Land that is overused or misused can become degraded, where the quality of land has been reduced and it is less productive. (4, 11)
  • Land that is suitable for farming. (12, 4)
  • The combined processes of evaporation and transpiration. In practice it is very difficult to calculate the two amounts separately, so they are often grouped together. (18)
  • The process of land turning into desert. This can happen because of natural factors like rising temperatures and drought, or human factors like overgrazing and deforestation. (15)
  • The upwards movement of water. (9, 6)
  • Water moving within rocks below the ground. (11, 4)
  • When evapotranspiration has exceeded precipitation for a long period. During these arid periods deep groundwater will have to be used or artificial stores e.g. reservoir. (11, 7)
  • When precipitation exceeds evaporation and groundwater is recharged. When there is excess water the ground will become saturated and the water table will move up. (11, 6)
  • When precipitation exceeds evapotranspiration and groundwater depleted in drier months can be refilled. (11, 8)
