cycle Flashcards
Transpiration
- Water drawn from the soil by plants
- Then evaporated into the atmosphere from leaves and stems
drainage basin
- an area of land drained by a river and its tributaries
- includes water found in the water table and surface run-off.
- There is an imaginary line separating drainage basins called a watershed.

Atmosphere
Hydrosphere - water source
Biosphere - soil store
Ground store - Aquifer
Evaporation
Liquid - gas
Evapotranspiration
Sum of evaporation from the land surface plus transpiration from plants
Sublimation
Conversion between solid and gas - No liquid stage
Precipitation
Input of water to drainage basin
rain, snow, hail, sleet
Throughfall
Precipitation penetrates through the canopy
Reaches soil surface by drip
Stemflow
Water running down a plant stem or tree trunks
infiltration
Water soaks or filters into the soil
Percolation
Gravity flow of water within the soil
Groundwater flow
It is governed by amount of water in system
Base flow
Water from the ground, flowing into channel over a long time with a certain delay
