Irrigation systems are designed to supplement the lack of rainfall
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Irrigation systems are designed to supplement the lack of rainfall.

After a rain event, where does water flow?
- A.
Downward into the water table
- B.
A wastewater treatment facility
- C.
A water treatment facility
- D.
Into a nearby river or stream
Correct Answer
D. Into a nearby river or streamExplanation
After a rain event, water flows into a nearby river or stream. This is because rainwater accumulates on the ground and follows the natural slope, eventually finding its way into the nearest body of water. This process is known as surface runoff, where the water moves over the land surface and into channels, eventually reaching rivers or streams. The water then continues its journey downstream, eventually making its way to larger bodies of water such as lakes or oceans.Rate this question:

C. City of Public WorksExplanation
If you see a neighbor or business facility violating water conservation regulations, you would call the City of Public Works. They are responsible for managing and maintaining public infrastructure, including water systems. They have the authority to enforce water conservation regulations and take appropriate action against violators. The local water district office may also be involved in water management, but the City of Public Works is the most appropriate contact for reporting violations. 911 is an emergency hotline and should only be used for immediate threats to life or property. Ghostbusters is a fictional entity and not a real contact for reporting violations.Rate this question:

A. An area of land that catches rain and snow draining or seeping into a body of waterExplanation
A watershed is an area of land that collects rain and snowfall, which then drains or seeps into a body of water such as a river, lake, or ocean. It acts as a natural boundary for the flow of water, determining where it will ultimately end up. Watersheds are important because they play a crucial role in supplying water to ecosystems, as well as providing a source of drinking water for human populations. They also help to regulate the water cycle and filter pollutants before they reach the water bodies.Rate this question:

Which of the following uses less water?
- A.
Washing dishes under a running tap
- B.
Washing dishes in a fully loaded automatic dishwater without pre-rinsing
Correct Answer
B. Washing dishes in a fully loaded automatic dishwater without pre-rinsingExplanation
Washing dishes in a fully loaded automatic dishwasher without pre-rinsing uses less water because the dishwasher is designed to use water efficiently. The dishwasher sprays water in a controlled manner and recirculates it, minimizing water waste. Additionally, a full load ensures that the dishwasher is being used to its maximum capacity, reducing the need for multiple cycles and conserving water further. Pre-rinsing dishes under a running tap, on the other hand, can lead to excessive water usage as the tap continuously runs while the dishes are being cleaned.Rate this question:

- A.
Infiltration
- B.
Hydrazation
- C.
Soaking-up
- D.
Speculation
Correct Answer
A. InfiltrationExplanation
Infiltration is the correct answer because it refers to the process of water entering the soil from the ground surface. This occurs when water seeps into the soil through the tiny spaces between soil particles. Infiltration is an important process in the water cycle as it helps to recharge groundwater and replenish soil moisture.Rate this question:

How much water used for irrigating lawns and gardens, on average, is wasted due to runoff and evaporation?
- A.
10%
- B.
25%
- C.
15%
- D.
50%
Correct Answer
D. 50%Explanation
On average, 50% of water used for irrigating lawns and gardens is wasted due to runoff and evaporation. This means that half of the water applied to lawns and gardens does not effectively reach the plants and instead is lost through runoff or evaporates before it can be absorbed. This high percentage of water wastage highlights the importance of using efficient irrigation methods and techniques to minimize water loss and conserve this valuable resource.Rate this question:

_______ of water are needed to make 1 pair of jeans.
- A.
15 gallons
- B.
150 gallons
- C.
1500 gallons
- D.
1000 gallons
Correct Answer
C. 1500 gallonsExplanation
To make 1 pair of jeans, a large amount of water is required. The given answer of 1500 gallons seems to be the most reasonable choice. This is because the production of jeans involves various processes such as growing cotton, dyeing the fabric, and washing the finished product. Each of these stages requires water, and considering the scale of the textile industry, 1500 gallons is a plausible estimate for the amount of water needed to produce a single pair of jeans.Rate this question:

Most fresh water is used for ________.
- A.
Generating electricity and irrigation
- B.
Gas/oil drilling and fire fighting
- C.
Manufacturing
- D.

A. Generating electricity and irrigationExplanation
Fresh water is primarily used for generating electricity and irrigation. Generating electricity often requires large amounts of water for cooling purposes in power plants, while irrigation involves the use of water to supply crops with the necessary moisture for growth. These two activities are major consumers of fresh water resources. While manufacturing and aquariums may also require water, they do not account for the majority of fresh water usage compared to electricity generation and irrigation.Rate this question:
