1. QQ:
What things affect the amount of ground water present in an area?
How has the amount of water present on Earth today changes from the days of dinosaurs?
List a five of ways
the humans affect
the water cycle.
What is the largest
greenhouse gas?

2. What things affect the amount of ground water present in an area?
Amount of water used
Changes in weather and climate
Type of soil & rock
Ground cover (grass vs asphalt)
Slope of ground
Air temperature
Land use
Surface runoff

3. The amount of water is the same although its distribution changes
2. How has the amount of water present on Earth today changes from the days of dinosaurs?
The amount of water is the same although its distribution changes

4. Recharing the aquifer (pits & injection)
3. List a five of ways humans affect the water cycle.
Recharing the aquifer (pits & injection)
Storing water reduces runoff (sea level drops)
Great withdrawls for irrigation, industry, and human use
Add substances
to the water
(intentional &
unintentional)
Deforestation

5. What is the largest greenhouse gas?

6. Fresh water: naturally occurring water having low concentration of salt & other solids
Includes ice sheets, ice caps, glaciers, icebergs, surface H2O, & groundwater
Excludes seawater & brackish H2O 

7. The measure of all salts dissolved in H2O
Salinity
The measure of all salts dissolved in H2O

8. Seawater: water from sea or ocean.
Average salinity is about 3.5% or 35 parts per thousand. This means that for every 1 liter of seawater there are 35 grams of salts dissolved in it. 

9. Brackish water:
* more salinity than freshwater but not as much as seawater
* result from mixing of seawater with fresh water, as in estuaries brackish fossil aquifers.
