Key Words Flashcards
Evapotranspiration
The combined moisture loss from evaporation and transpiration from an area
Evaporation
That phase change of water from liquid to gas
Groundwater flow
The vertical movement of groundwater through permeable rocks. It may eventually reach the surface to form springs or flow directly into streams, rivers and the ocean
Infiltration
The vertical movement of water under the pull of gravity from the ground surface into the soil
Interception
When vegetation stops water from reaching the ground
Overland flow
The movement of water across the ground as a thin film or sheet
Percolation
The vertical movement of water under the pull of gravity from soil into permeable rocks
Precipitation
Moisture in the form of rain, drizzle, sleet, snow, hail etc which falls from clouds
Runoff
The movement of water across the ground surface in gullies streams and rivers
Stemflow
Precipitation, initially intercepted by vegetation which runs to the ground along branches and stems
Throughfall
Precipitation initially intercepted by the leaves , stems, branches of vegetarians which drips to the ground
Throughflow
The lateral movement of water through the soil to streams and rivers
Transpiration
The evaporation of moisture produced by the pores of plants from vegetation surfaces
Water table
The upper surface of groundwater
