    • 1.  97%- Salt Water  3%- Fresh Water  79%- Ice Water  20%- Ground Water  1%- Surface Water
    • 2.  Water Quality- Measure of the amount of substances besides water in a water sample; description of how pure water is.  Potable Water- Water that is safe for humans to drink.
    • 3.  The most common substance other than water found in a water sample is salt. Over 97% of water on earth is salt water
    • 4.  We Test For  Taste and Odor  Turbidity  Toxic Substances  PH  Dissolved Oxygen  Solids  Dissolved Solids
    • 5.  Water moves in waves caused by wind. Waves form from convection currents in the water.
    • 6.  The Gravitational pull of the moon.  Also the gravity of the sun and rotation of the earth.
    • 7.  Waves erode the shore by dropping off and taking sediment to and from the shore.
    • 8.  What the river is like in terms of Length, width, speed, depth etc.
    • 9.  Ocean Basins- saucer like impressions under the ocean formed form plate tectonics  Continental Drainage- where all the water on the east or west side of the divide flows into.
    • 10.  Drumlin, Kettle Lake, Erratic, Moraine and eskers
    • 11.  Water hold heat longer so cities near large bodies of water have warmer climates  Water reduces the amount of extreme high and low temperatures
    • 12.  A Chinook is caused when winds from the Pacific go over the rocky mountains and warm then blow down onto the prairies of Alberta.
    • 13.  Humans effect water quality negatively by pollution and positively by filtering the water.
    • 14.  Scientists monitor water continuously so they can identify a change in quality before it becomes to serious.
    • 15.  Precipitation,Evaporation,Condensation
    • 16.  http://www.allaboutwater.org/tap-water.htm  http://www.50plus.com/Health/BrowseAllArti  http://news.nationalgeographic.com/news/
    • 17.  Never put water down the storm drain  Make sure places like toilets have no leaks  Take shorter showers
    • 18.  If water quality is good, living things keep living.  If water quality is bad, living things die off.
    • 19.  Glaciers and icecaps have shaped mountains, lakes, hills and oceans and also left rocks behind like erratic and other debris( moraines ).
