basin drainage system

Question 1

evaporation

Answer 1

the process in which liquid changes to water vapor from puddles/streams. evaporation rates increases in hot/dry/windy conditions and with larger soil surface area

Question 2

transpiration

Answer 2

when water is drawn from the soil into the plant and leaves the plant as water vapor through the stomata.

Question 3

evapotranspiration

Answer 3

processes where water moves from a land surface to the atmosphere via evaporation or transpiration

Question 4

stomata

Answer 4

small pores on the surface of leaves. regulates gas exchange

Question 5

potential evapotranspiration

Answer 5

the amount of evaporation that would occur if an unlimited water source were available.

Question 6

river discharge

Answer 6

volume of water that flows into the sea or that moves in channels {rivers/streams} water enters the channel as direct precipitation or other flows.

Question 7

direct channel precipitation

Answer 7

precipitation {snow/rain/sleet} that falls directly onto the surface of a river/stream channel.

Question 8

Q=AV
Q?
A?
V?

Answer 8

Q = Discharge,
A = Cross Sectional Area,
V= Velocity
Measured in m3/second – Cumecs.

m3/s = cubic meter per second
