Rainfall
Groundwater
Ocean water
Snowmelt
#2

What is the term for the process by which water vapor changes into liquid water?

Condensation
Evaporation
Transpiration
Precipitation
#3

What is the term for the volume of water flowing through a river or stream per unit time?

Discharge
Velocity
Capacity
Concentration
#4

What is the term for the process by which water is absorbed by soil and becomes groundwater?

Infiltration
Percolation
Capillary action
Exfiltration
#5

What is the main driver of the water cycle?

Wind
Heat from the sun
Ocean currents
Volcanic activity
#6

What is the term for the process by which water is stored in underground formations such as aquifers?

Groundwater recharge
Groundwater discharge
Groundwater flow
Groundwater storage
#7

What is the name for the movement of water through the ground?

Percolation
Infiltration
Seepage
Erosion
#8

What is the formula for calculating the hydraulic conductivity of a porous medium?

K = Q/A
K = (h2 - h1) / L
K = (Q/A) * (h2 - h1) / L
K = Q * L / (A * (h2 - h1))
#9

Runoff
Percolation
Sublimation
Transpiration
#13

What is the main factor influencing the rate of evaporation from a water surface?

Temperature
Humidity
Wind speed
Atmospheric pressure
#14

Which of the following is NOT a factor affecting the porosity of a rock or soil?

Grain size
Shape of grains
Depth of water table
Sorting of grains
#15

What is the name for the area of land that drains into a particular river or stream?

Watershed
Aquifer
Floodplain
Estuary
#16

What is the term for the phenomenon where water in the soil moves upward due to capillary action?

Density
All of the above
#18

What is the term for the boundary between the zone of aeration and the zone of saturation in an aquifer?

Water table
Piezometric surface
Hydrostatic gradient
Perched water table
