2.7 - Climate Change Affecting Trends

Question 1

Precipitation Trends (Given CC)

Answer 1

Increases only seen in Sahel, Asia, Greenland & Antarctica

Question 2

Evaporation Trends (Given CC)

Answer 2

Increases meaning increased transpiration and less water reaches the soil

Question 3

Water Store Trends (Given CC)

Answer 3

Terrestrial water storage decreases as more water evaporates and is released into the atmosphere

Question 4

Effect On Water Flows (Given CC)

Answer 4

Extreme heat minimises rainfall and water flow, drying shallower areas and causing potential death/migration of organisms.

Question 5

Effect On Snow/Glacier Masses (Given CC)

Answer 5

Decreases, negatively effecting indigenous people as it creates food shortages.

Question 6

Effect On Lakes (Given CC)

Answer 6

More dependant on local characteristics

Question 7

Permafrost (Given CC)

Answer 7

Melting and thawing increases, affecting water quality, security and health.

Question 8

Precipitation (As CC Continues)

Answer 8

Rain will become more intense, the tropics will get hotter and see more rain whilst South Africa and Europe will get less.
However, Europe sees less water stored as snow and therefore will see more rain.

Question 9

Runoff (As CC Continues)

Answer 9

Temp increases run-off, due to more intense rainfalll and less infiltration.
More droughts in-between due to increased evapotranspiration

Question 10

Evaporation (As CC Continues)

Answer 10

More over oceans however more clouds so less sun intensity.
More transpiration from vegetation and less water in soil.

Question 11

Soil Moisture & GW (As CC Continues)

Answer 11

More dependant on human extraction

Question 12

Permafrost (As CC Continues)

Answer 12

Permafrost will degrade with higher temperatures
