Question

The benefits of dams include all of the following "except" 28 generating electricity (pollution free) a b providing flood control for areas downstream of the damm providing potential recreational benefits for people increasing the quality the habitat for native fish, etc, upstream and downstream of the dam c d e providing a more stable, year round source of water in some area 29 a. removal/pumping of too much fresh water from an aquifer near a coastal region Many fresh water wells in coastal areas now yield salty water. The main cause of this problem is acid rain dissolving minerals and salts on the surface which eventually go to the water table. c. sewage, loaded with salty foods, improperly treated, and discharged (pumped) back into aquifers d. rising sea level causes excess salt water to e. too much leaching from garbage from the landfills above contaminate many surface water supplies 30 Underground limest cause ? a an definite increase in the hydrostatic pressure of the remaining water below ground b the hydrostatic pressure of the remaining water would remain the same c salt water intrusion d sink holes e non point source problems tone cavems, once filed with groundwater but now depleted of water would likely Which one below does "not belong in the Long Island aquifer system ? a 31 Lloyd b.

In class we stated that Nassau County was refused permission to put a bunch of high pumping wells near the a. a point source pollution b. a sink hole c. a confined aquifer d. a cone of depression e. an aquitard Suffolk border because it causes 34. The best ways to conserve the amount of water used by agriculture is the process of drip irrigation a. b. c. center-pivot sprinkle irrigation half pivot irrigation method d. reverse osmosis irrigation e use the flooding of the field method 35. Porosity means a. how fast water can pour over a dam b. a term used to describe how fast rainwater is falling from a storm c the rate at which an open body of water (eg pond) will fil d. is a measure of the ease with which a fluid (water in this case) can move through substances. e. the percentage of open space between soil particles which could fill with water
