| Question | Answer |
|---|---|
| what type of water has the greatest abundance? | oceans |
| do lakes, rivers, streams contain more or less water than groundwater? | less |
| what type of water would be easiest to access for drinking? why? | surface fresh water is the easiest unless you have the technology to drill a well |
| what volume measurement unit was used to label water classification types of earth? | mL and cubic miles |
| in the loop lake activity, what was the area that was connected by "z's" called? | watershed |
| would the increasing or decreasing of nutrients be harmful in the loop lake activity? | increasing |
| would the increasing or decreasing of turbidity in the loop lake activity be harmful? | increasing is harmful |
| would the increasing or decreasing of dissolved oxygen be in the loop lake activity be harmful? | decreasing is harmful |
| in the watershed activity what are the three types of land that are beneficial to the watershed? why? | forests, wetlands, and grasslands. they store a lot of water |
| why are street and residential areas bad for the watershed? | they don't store water causing runoff |
| why is conserving water important? | (your own reason) |
| what are three ways to conserve water? | stopping leakage, using gray water, don't leave water running |
| how can you improve the health of a watershed in a construction site? | build a fence around a house to catch sliding soil etc. if the house is on a hill |
| how can a homeowner improve the health of a watershed? | cleaning up their messes so that they don't seep into the soil and ruin the water underneath |
| how can farmers improve the health of a watershed? | by not using too much fertilizers |
| pollution plume | An area of a stream or aquifer containing degraded water resulting from migration of a pollutant. |
| infiltration | the process by which water penetrates into soil from the ground surface, or the penetration of water from the soil into a sewer system |
| runoff | the water from rain, snowmelt or irrigation that flows over the land surface and is not absorbed into the ground, instead flowing into streams or other surface waters or land depressions |
| transpiration | evaporation from vegetation and the soil |
| precipitation | water falling to earth |
| unconfined aquifer | An aquifer in which there are no confining beds between the capillary fringe and land surface |
| dissolved oxygen | measure of the amount of oxygen that is dissolved or carried |
| turbidity | muddiness created by stirring up sediment |
| nutrients/fertilizers | chemical that an organism needs to live and grow or a substance |
| confined aquifer | underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well |
| wetlands | an area of land whose soil is saturated with moisture either permanently or seasonally |
| contour lines | a line drawn on a map connecting points of equal height |
| glacier | a slowly moving mass of ice |
| state standard | The stable and pure form of a substance at standard pressure and a specified temperature |
