Flashcards in Natural changes in water cycle over time Deck (42):
1

hurricanes

increased precipitation - localised flooding
increased erosion of river banks
due to precipitation there is more water
throughflow and groundwater flow will increase

2

high temperatures

more water vapour through increase evaporation
water vapour builds up causing big storms

3

vegetation

summer - grows rapidly increasing interception and transpiration
winter - vegetation dies back reducing interception and transpiration

4

evaporation

summer - higher temps encourage rapid evaporation
winder - lower temps reduce evaporation ( water stored as ice on land so cant evaporate)

5

drought

heat and dry air cause high rates of evapotranspiration. drought causes reduction in water stores in rivers and lakes

6

precipitation

summer - total rainfall less but storms more frequent
winter - greater quantities of rainfall with a chance of snow
