1.1 The Drainage Basin System Flashcards
(24 cards)
the cycle of water between the atmosphere, lithosphere and biosphere (around the planet) is known as…
the hydrological cycle
a drainage basin is an area that is …………………. by a river.
drained
Evaporation is an …. that is the process by which a liquid is changed into a …
output
gas
evaporation increases…and so losses are greater in…
under warm, dry conditions
arid and semi-arid climates
evaporation decreases…and so losses are lower in…
under cold, calm condistions
polar regions
factors affecting evaporation include…the most important factor is…but other factors include…
temperature, humidity and wind speed
temperature
water available, vegetation cover and albedo
transpiration
process where water vapour escapes from plants
evapotranspiration
the loss of water from a drainage basin into the atmosphere from the leaves of plants + loss from evaporation.
EVT
evapotranspiration
precipitation is an…of a drainage basin and is condensed moisture in the atmosphere in the form of rain, sleet, snow etc.
input
PPT
precipitation
interflow
water flowing downhill through permeable rock above the water table
throughflow
the movement of water downslope within the soil layer. Throughflow is fast through pipes
percolation
the gravity flow of water within the soil.
water vapour is when liquid is changed into…
a gas suspended in the atmosphere
confluence
where two rivers meet
hydrological cycle
the movement of water between the atmosphere, lithosphere and biosphere
infiltration
describes when precipitation enters the soil
stemflow
water running down a plant stem or tree trunk
overland flow
aka as surface runoff is when precipitation flows over the land
interception
when vegetation interrupts the flow of precipitation from the atmosphere to the ground
surface runoff/overland flow
the movement of water over the surface of the land, usually when the ground is saturated or frozen or when precipitation is too intense from infiltration to occur
potential evapotranspiration
