climate change

Question 1

impact on precipitation

Answer 1

• warmer atmosphere= greater water holding capacity = more evaporation
• increased precipitation in tropics
• decreased precipitation in sub tropics

Question 2

impact on surface run off and stream flow

Answer 2

more surface run off=flash flooding

BUT drought as less infiltration to groundwater

Question 3

impact on groundwater flow

Answer 3

decreased in areas of drought

Question 4

impact on reservoir, lake storage

Answer 4

storage descreases as evaporation increases

Question 5

impact on soil moisture

Answer 5

less as more evaporation but more rain in some areas so may not change

Question 6

impact on permafrost, snow, glacier ice

Answer 6

melting = increased discharge in rivers=burst banks=fluvial flooding
-permafrost melting releases methane
