Term
When is water most dense?
Definition
4 degrees C!

Humidity
Definition
amount of water vapor in the air

Saturation Point
Definition
When a certain volume of air is saturated. Depends on Temperature.
Term

Any unwanted or discarded material we produce that is not a liquid of a gas.
Term
Municipal vs Industrial Solid Waste
Definition
Produced by homes vs produced by industries.
Term
Hazardous (toxic) waste
Definition
threatens human health or the environment because it is toxic, chemically active, corrosive or flammable.
Term
What should be the 3 top priorities for solid and hazardous wastes?
Definition
1st: Primary pollution and waste prevention. 2nd: Secondary pollution and waste prevention. 3rd: waste management.
Unfortunately we often rely heavily on the 3rd method only. Look up more about all 3 in the textbook!
Term
Name the 5 Rs
Definition
Refuse, Reduce, reuse, re-purpose and recycle
Term
refuse
Definition
don't buy something unless you need it!
Term
Close loop vs secondary recycling
Definition
Used again for the same purpose vs used for something new!
Term
What is the average residency time for water in the ocean?
Definition
3000 years!
Term
What are the largest reserves of freshwater?
Definition
Ice and then ground water and then land water?
Term
Water table is
Definition
the top of the zone of saturation
Term
Lake and Pond definition
Definition
Lake- inland depression that has FW year around. Pond- shallow and small enough for rooted plants to for no most of it's bottom.
Term
Atmosphere
Definition
Is the smallest FW reserve and has the fastest turnover!
Term
How much water from rivers and streams can we store?
Definition
1/3. The rest is in floods that are too violent for us!
Term
Every continent has a drought cycle, how long is ours?
Definition
30 years
Term
Withdrawal
Definition
Total amount of water taken from a source
Term
Consumption
Definition
fraction of withdrawed water that is the made unavaliable for other purposes.
Term
How much water does the average US citizen use a day?
Definition
1400 gallons!
Term
degradation of water
Definition
change in water quality due to contamination making it unsuitable for a desired purpose!
Term
What 2 tests are commonly done for groundwater?
Definition
E-coli and nitrates!
Term
Ground water is the source of nearly what percent of FW in the US?
Definition
40%
Term
Ogallala Aquifer
Definition
critically important for US food production. Has no discharge because it's fossil water. 2/5ths is gone and it has fallen over 100 ft since 1940!
Term
Ways to increase water supplies?
Definition
Cloud seeding (steels from others), iceberg towing, and desalination.
Term
Monolake
Definition
700,000 years old. use ot be 60 times larger. 1/3 has been diverted for human use. No outlet makes it naturally salty and alkaline. Finally protected in 1994.
Term
