SeasonalChanges&Vegetation

    Cards (6)

    • What varies with the seasons?

      the size of inputs, flows and stores in the water cycle
    • What happens to temperatures during WINTER?

      • May drop to below 0c
      • this causes water to freeze
      • This can reduce size of flows through drainage basins , while the store of frozen water grows
      • WHEN TEMPS INCREASE AGAIN flows through drainage basins can be much larger as the ice melts
    • what do most plants show?
      Seasonal variation
    • What does vegetation do?
      intercepts precipitation and slows its movement to the river channel
    • when is interception highest|?

      when there is lots of vegetation and deciduous trees have their leaves
    • the more vegetation there is in a drainage basin...?
      the more water is lost (through transpiration and evaporation directly from vegetation) before it reaches the river channel, reducing runoff and peak discharge
