2.2/3 Water Cycle
- Hydrosphere
- All the water on earth
- Atmospheric
- Can be found in all 3 forms (Solid/Liquid/Gas)
- Clouds
- Global warming
- Water Vapour is a greenhouse gas regulating temperatures
- Cryospheric
- Solid forms of water (Ice)
- Ice Sheets
- Glaciers
- Ice Caps
- Permafrost
- Sea Ice
- Oceanic
- Oceans cover 72% of earth's surface
- Oceans/Seas
- Largest store of water, holds 72% of all water on earth
- Falling pH
(becoming more
Acidic)
- Terristrial
- Fresh
- Surface Water
- Lakes/RIvers
- Ground Water
- Soil Water
- Biological
- Biomass
- Plants/Animals
- Factors Driving the Change in Magnitude of Water Stores
- Evaporation
- Depends on...
- Availability of water
- Temperature
- Huminidity
- Solar radiation
- Liquid to Gas
- Condensation
- Depend on...
- Air temperature reduces
- Volume of air increases
- Causes Precipitation
- Gas to Liquid
- Drainage Basin
- Open System
- Cascading System
- Area of land drained by a river + its
tributaries
- Boarder
- Water shed
- Inputs
- Precipitation
- Stores
- Rivers
- Lakes
- Water table
- Soil
- Interception
- Vegetation collect and hold water (on leaves)
- Processes
- Stem Flow
- Flow of water down plants/animals to the ground
- Infiltration
- Movement of water through the soil
- Through flow
- Very similar to infiltration but it is faster
- Percolation
- Movement of water through rocks to the water table
- Ground Water flow
- Movement of water through ground water storage (V slow)
- Channel flow
- Movement of water in a river
- Surface run-off
- Movement of water across the surface
- Outputs
- Evaporation
- Transpiration
- Recirculation of Water (Globally)
- Ocean - Land- Ocean
- Atlantic - North America - Atlantic
- Evaporates from the ocean - precipitation to land -
process takes it back to ocean
- Ocean - Ocean
- Pacific - Pacific
- Water remains in the ocean
- Land - Land
- Water doesn't enter the ocean
- precipitation onto land - transpiration into atmosphere
- Greater occurrence in tropical areas
- Equator
