The physical cycle
Water falling from the sky as rain, snow, or sleet.
Precipitation
Liquid water turning into water vapor
Evaporation
The largest store of water on the planet.
Ocean
Runoff from farms that leads to algae blooms.
Eutrophication
On a diagram, what do arrows usually represent?
flows
Water soaking vertically into the soil
Infiltration
Water vapor cooling down to form clouds.
Condensation
An underground layer of rock that holds water.
Aquifer
Pollution from a single, identifiable source like a pipe.
Point source
Identify the process where water moves horizontally through soil.
Throughflow
Water flowing over the land surface into rivers
Surface runoff
The combined process of evaporation and plant "sweat."
Evapotranspiration
Water held in the ground below the water table.
Groundwater
A measure of how cloudy or murky water is.
Turbidity
In a water budget, what does 'P' stand for?
Precipitation
Water moving sideways through the soil.
Throughflow
When ice turns directly into water vapor without melting.
Sublimation
The average time a water molecule stays in a store.
Residence time
The type of "Shield" you'd use to keep hair dye from washing away.
Cold water
Identify the horizontal movement of water in the atmosphere
Advection
The process where water moves from the surface to deep rock
Percolation
Energy absorbed/released during a phase change.
Latent heat
When more water is taken out than put back into an aquifer.
Over-abstraction
Toxic substances like lead or mercury in the cycle.
Heavy metals
Calculate the water budget if P=100, E=60, and R=30
