Natural changes in water cycle over time

Question 1

hurricanes

Answer 1

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

Question 2

high temperatures

Answer 2

more water vapour through increase evaporation

water vapour builds up causing big storms

Question 3

vegetation

Answer 3

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

Question 4

evaporation

Answer 4

summer - higher temps encourage rapid evaporation

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

Question 5

drought

Answer 5

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

Question 6

precipitation

Answer 6

summer - total rainfall less but storms more frequent

winter - greater quantities of rainfall with a chance of snow
