2.2/3 Water Cycle

Hydrosphere
1. All the water on earth
2. Atmospheric
  1. Can be found in all 3 forms (Solid/Liquid/Gas)
  2. Clouds
  3. Global warming
    1. Water Vapour is a greenhouse gas regulating temperatures
3. Cryospheric
  1. Solid forms of water (Ice)
  2. Ice Sheets
  3. Glaciers
  4. Ice Caps
  5. Permafrost
  6. Sea Ice
4. Oceanic
  1. Oceans cover 72% of earth's surface
  2. Oceans/Seas
  3. Largest store of water, holds 72% of all water on earth
  4. Falling pH (becoming more Acidic)
5. Terristrial
  1. Fresh
  2. Surface Water
    1. Lakes/RIvers
  3. Ground Water
  4. Soil Water
  5. Biological
    1. Biomass
      1. Plants/Animals
Factors Driving the Change in Magnitude of Water Stores
1. Evaporation
  1. Depends on...
    1. Availability of water
    2. Temperature
    3. Huminidity
    4. Solar radiation
  2. Liquid to Gas
2. Condensation
  1. Depend on...
    1. Air temperature reduces
    2. Volume of air increases
  2. Causes Precipitation
  3. Gas to Liquid
Drainage Basin
1. Open System
  1. Cascading System
2. Area of land drained by a river + its tributaries
3. Boarder
  1. Water shed
4. Inputs
  1. Precipitation
5. Stores
  1. Rivers
  2. Lakes
  3. Water table
  4. Soil
  5. Interception
    1. Vegetation collect and hold water (on leaves)
6. Processes
  1. Stem Flow
    1. Flow of water down plants/animals to the ground
  2. Infiltration
    1. Movement of water through the soil
  3. Through flow
    1. Very similar to infiltration but it is faster
  4. Percolation
    1. Movement of water through rocks to the water table
  5. Ground Water flow
    1. Movement of water through ground water storage (V slow)
  6. Channel flow
    1. Movement of water in a river
  7. Surface run-off
    1. Movement of water across the surface
7. Outputs
  1. Evaporation
  2. Transpiration
Recirculation of Water (Globally)
1. Ocean - Land- Ocean
  1. Atlantic - North America - Atlantic
  2. Evaporates from the ocean - precipitation to land - process takes it back to ocean
2. Ocean - Ocean
  1. Pacific - Pacific
  2. Water remains in the ocean
3. Land - Land
  1. Water doesn't enter the ocean
  2. precipitation onto land - transpiration into atmosphere
  3. Greater occurrence in tropical areas
    1. Equator
