What is infiltration
Movement of water vertically from the ground surface into the soil
What is percolation
Movement of water vertically from the soil into the bedrock
What is evaporation
When liquid water ris heated and becomes water vapour
What is condensation
When water vapour cools and forms liquid water
What is transpiration
When moisture is carried from a plants roots to its pores where it changes to vapour and is released
What is surface run-off / overland flow
Movement of water across the land surface either when the ground is saturated or when infiltration capacity is exceeded
What is ablation
The loss of ice and snow especially on a glacier through melting, evaporation and sublimation
What is precipitation
Moisture (rain,snow,hail etc) falling from the clouds towards the ground
What is sublimation
The phase change if water from ice to vapour
What is channel flow
The movement if water withing the river channel
What is through flow
Water flowing horizontally through the soil to stream and river channels
What is groundwater flow
The horizontal movement of water within aquifers or bedrock
What is leaf drip
Water falling to the ground from leaves of vegetation
What is stemflow
The flow of water along branches and stems of trees and other plants to the ground
What is interception
When rainwater is stored temporarily on leaves, stems and branches of vegetation
What is capillary action
The upward movement if water through channels in a substance
