Water sources and Water use
This agricultural practice accounts for 40% of human water consumption.
Irrigation
The two processes moving water between oceans and land
Evaporation and precipitation
What percentage of Earth's water is freshwater?
3%
Leaking underground storage tanks threaten this water source
Groundwater
This material should fill protective casing around water mains
Cement grout
Two-thirds of Earth's freshwater is locked here
glaciers/ice caps?
Plant water release through leaves, a critical component of the water cycle.
Transpiration
What percentage of Earth's freshwater is accessible for human use?
1%
Wastewater containing human/animal pathogens is called this
Black water
A continuously flowing natural water source.
Perennial stream
This includes bodies of water on the land's surface
(give 3 examples)
Surface Water- rivers, lakes, oceans, ponds, Reservoirs
Fog represents this phase of the water cycle near Earth's surface.
Condensation
This type of water source holds around 30% of Earth's freshwater and exists below ground.
Groundwater
This 1972 law protects U.S. waters from industrial pollution
Clean Water Act
how do tanks contribute to water distribution
Water tanks store water and help keep steady pressure so water can flow smoothly to homes and businesses. They also provide extra water during busy times or emergencies.
A continuously flowing water source that flows all year long.
perennial stream
The energy source driving all water cycle processes.
The Sun
Glaciers and ice caps hold this percentage of Earth's freshwater.
68%
(more that 50%/ the majority)
Oil spills affect water quality through this chemical process.
Contamination
The required sample size for lead/copper water testing.
1 liter
Groundwater can take this long to travel one mile
What is a human lifetime?
This sphere contains frozen water interacting with the hydrosphere.
Cryosphere
The process by which water moves into soil layers, replenishing groundwater
Infiltration
The chemical formula for chlorine gas used in water treatment
Clâ‚‚
Groundwater movement speed through impermeable layers
Extremely slow to the point it can take a entire human life span
