Driving force behind water cycle
solar radiation
interception
water is trapped by vegatation/structures etc
infiltration
water reaches soil
groundwater
water under clay/rock underground
runoff
urban areas with low inflitration
transpiration
evaporation of water from interior of plants eva
evapotranspiration

permanent feature. stratification
temperate zone thermocline
only in the summer
solution
liquid that is a mixture of 2+ things
solvent
dissolving agent
solute

aqueous solution

diffusion

equatorial upwelling
deep cold water replaces warmer surface waters
coastal upwelling
winds move surface water offshore and cold water replaces it
spring tides
when the sun and the moon are aligned and tides are largest
endorheic basins
