1.3 changes in the magnitude of the water cycle

  1. Using Fig 1 on P12 organise the list of water storage in order of duration  Card sort

  2. Soil, seasonal snow/rivers, glaciers, lakes, shallow groundwater, deep groundwater

  3. Can they be linked as flow diagrams?

  4. Glaciers/snow --> rivers --> lakes --> soil --> shallow groundwater --> deep groundwater

  5. What processes can change how or where water is stored?

  6. Evaporation, freezing, percolation

  7. Where do changes occur?

  8. In flows and transfers

Global Air Circulation

  1. Add diagram

  1. Describe the GAC

  2. Air circulates in alternating directions in the cells in the atmosphere and the air flows in alternating directions depending on the latitude, alternating low and high pressure through the rise and descent of the air, creating different ecosystems linked to the weather patterns. The different circulations are grouped into cells called the Hadley, Ferrel and polar cells. The Hadley cells create a low pressure giving warm and wet climates creating ecosystem's like rainforests, Ferrel cells create a low pressure making a temperate climate and there is high pressure at the poles and between the cells creating deserts with very little life

Cryosphere

  1. What is the equilibrium line

  2. The area between where snow and ice is accumulated, and the area where it is lost

  3. Can you identify 5 world cities affected if the sea level rises by 50metres?

  1. Jakarta, Bangkok, New York, Shanghai, Osaka

Local Scales – hillslope

  1. Find a similar image to Fig 4 on P14 and add to your notes

  1. Shortest store?

  2. Surface

  3. Longest Store?

  4. Groundwater

  5. Which part is?

  6. Most sensitive to Temperature

  7. Overland flow

  8. Most sensitive to a dam being built

  9. Stream flow

  10. Most sensitive to urbanisation

  11. Interception and evapotranspiration

  12. Most sensitive to deforestation

  1. Interception and evapotranspiration

  1. What is the effect of farming?

  2. Can cause deforestation which interrupts some processes

 

Soil Budget – Find similar graph to fig 5 P15

 

  1. Describe the pattern of the graph in relation to the water cycle eg

 

  1. Describe and think of reasons how would a desert be different to a rainforest

  2. Having more water in the soil that allows water to absorb into the soil and be held there as a store from the winter and spring months, where there will be a greater water budget, compared to summer where there is a lower water budget, rather than sand which doesn’t have as good an ability to hold water, as there is less rainfall in the desert where it is almost constantly raining in the rainforest

  3. See if you can find examples – share

  1. Amazon rainforest vs Sahara desert

  1. Can you think of a knock-on effect a dry winter might have on the summer phase

  2. There will be less water in the soil for the soil budget, which will decrease even more with the lack of rainfall and greater evapotranspiration throughout the summer months

  3. Or a wet summer with heavy rains

  4. There will be a water surplus in the soil which will lead to saturated soil and therefore flash flooding in the spring when the rainfall cannot be absorbed

Some good points

You need to add depth to you soil budget answers eg Q7/8 how does it affect the soil budget not just plants
