- Relative humidity
- amount of water vapor as a percentage of what the air can hold at a particular
- Infiltration
- when precipitation is soaked into groundwater
- Global Convection currents
- sun heats earth over equator- air rises
- Capillary water
- held in soil- returns via evaporation or transpiration
- Runoff
- when flows into streams and rivers
- Humidity
- amount of water vapor in the air
- Precipitation pattern
- depends on rising or falling air currents
- Nonrenewable groundwater
- when recharge rate is centuries or more
- Condensation
- When water molecules become liquid again
- Surface runoff loop
- water becomes part of surface water system
- Green water
- watervapor
- Rain Shadow
- Moisture filled air meets mountains
- Land subsidence
- water filled spaces in ground lose their water
- Sinkholes
- underground cavern
- Developing
- water is untreated to downstream people are left with contaminated water
- renewable groundwater
- replenished by percolation of precipitation water
- Purification
- as percolates, removes bacteria and debris, may dissolve and leach minerals
- Evapotranspiration loop
- water evaporates and returns by precipitation
- Aquifer exploitation
- ground water use exceeds aquifer
- Surface waters
- all ponds, lakes, streams, rivers on earth
- Nonconsumptive
- water remains available to humans for other users
- Consumptive
- water does not return to other water resource
- Recharge
- area where water enters an aquifer
- Blue water
- liquid water
- groundwater loop
- water perlocates and moves through
- Watershed
- all land area that contributes to a particular stream or water
