Lesson 10 - Climate Change + Hydro Cycle Components

Question 1

Evaporation + Evapotranspiration

Question 2

Groundwater flow

Answer 2

No definitive link with climate change
Human abstraction has larger impact

Question 3

Ice

Answer 3

Temp increase + changing precipitation
Glacial retreat since Little Ice Age
Thinning due to melting ice since 70s

Question 4

Precipitation input

Answer 4

Increase in intense events
However, overall amounts remained steady/decreased
Rain most dominant form

Question 5

Runoff + Stream Flow

Answer 5

Climate extremes = Hydro extremes
Accelerated cycle will increase run-off + reduce infiltration

Question 6

Ocean

Answer 6

Ocean warming = Evap.
Limited evidence of more cyclones

Question 7

Reservoir/lake/wetland storage

Answer 7

Lakes + reservoirs - regional variations
Not enough wetland evidence tbh

Question 8

Permafrost

Answer 8

Rising air + ocean temps
High latitude permafrost degradation
Affects groundwater supplies

Question 9

Soil moisture

Answer 9

Increases with precipitation

Question 10

Snow

Answer 10

Length of snow cover season has fallen
Snowmelt earlier
