| Which of the following describes a pH of 12? | High Alkalinity |
| A turbidity meter measures? | The amount of particles in the water. |
| Which of the following describes LandSat? | Technology that takes digital photographs that allows scientists to monitor changes within continents as well as coastal areas. |
| Which of the following describes a watershed? | An area of land with water systems draining into ocean. |
| Which of the following describes the availability of most of Earth's fresh water? | Can not be used because it is mostly found in polar ice caps. |
| Which describes the distrubution of water vs. land on Earth? | There is more water than land. |
| Which describes fresh water vs. salt water distrubution on Earth? | Earth is primarily abundant with ocean waters. |
| How are tributaries related to river discharge? | The increase of tributaries can increase the discharge of a river. |
| What are some nick names for watershed systems? | River Basin or Drainage Basin |
| How does rain effect the water table? | When rain is abundant, the water table will increase. |
| How can overusage of wells create damage to the water table? | The water supply from the water table can deplete and no longer be available. |
| How can water be both a renewable and nonrenewable resource? | The water cycle will always replenish Earth's water, but humans can overuse and pollute water that is presently available. |
| One way farmers can prevent water pollution is by ? | Refraining from the use of pesticides and fertilizers on crops. |
| How is eutrophication a source of water pollution? | Nitrates and phosphates serve as extra nutrients for the algae in the water, thus creating algae blooms. |
| Fresh water should be conserved because? | Less than one percent of freshwater is available for our use. |
| Using low flow toilets and low shower heads are examples of ? | How we can conserve water. |
| An example of a bio-indicator would include? | Dead fish floating on the top of a lake. |
| Excessively high temperatures can be a problem to a body of water because? | It can lead to a decrease of dissolved oxygen. |
| Why is a D.O. level below 4.0 mg/L considered unhealthy? | It can cause stress or even death in aquatic organisms. |
| When water from a river or stream slows down and drops or lays down sediments, this is called? | deposition |
| These are two different methods of disinfecting the remaining water from a water treatment plant. | UV light or chlorination |
| A reservoir is ? | A local body of water (such as a lake) used as a source of water. |
| Bacteria is used in the water treatment process to? | Remove unwanted bacteria. |
| This is generally the main type of nonpoint source pollution. | Run-off |
| These are general examples of point source pollutions. | Factories and industries |
| An aquifer is where which of the following is located? | Groundwater |
| Erosion is different from weathering because? | Erosion moves sediments from one location to another. |
