water transfer Flashcards
1
Q
what 4 factors effect
liquid –> gas
(evaporation)
A
- energy (solar radiation)
- availability of water
- humidity (saturated air = harder to evaporate)
- Temperature (hot = more evap)
2
Q
what is the main form of precipitation?
A
condensation
(gas –> liquid)
3
Q
what 2 factors cause condensation(precip)
A
- reduced air temp
- volume of air increases
4
Q
why does reduced air temperature cause condensation/precipitation
A
hot air holds more water vapour.
when cools, cannot hold as much
5
Q
what is a drainage basin
A
an area of land which is drained by a river and its tributaries
6
Q
what is the border/boundary around a drainage basin called
A
watershed
7
Q
is a drainage basin an open or closed system?
A
open
energy and matter can transfer in and out of the system
8
Q
what is a cascading system
A
the inputs and outputs of one open system (within the drainage basin system) flow into the input of another system.
