Questions and Answers

1.

How much water must a dairy cow drink to produce one gallon of milk?
- A.
  
  4 gallons
- B.
  
  1 gallon
- C.
  
  1/2 gallon
- D.
  
  25 gallons
Correct Answer
A. 4 gallons

Explanation
A dairy cow must drink approximately 4 gallons of water in order to produce one gallon of milk. This is because cows require a significant amount of water to maintain their overall health and milk production. Water is essential for digestion, nutrient absorption, and milk synthesis in cows. Therefore, a cow needs to consume a large amount of water to produce a relatively smaller amount of milk.

How much of the earth's surface is water?
- A.
  
  50%
- B.
  
  20%
- C.
  
  80%
- D.
  
  100%
Correct Answer
C. 80%

Explanation
Approximately 80% of the Earth's surface is covered in water. This includes oceans, seas, lakes, rivers, and other bodies of water. The remaining 20% is made up of land, including continents and islands. The large amount of water on Earth is essential for supporting life and regulating the planet's climate.

How much water does a dripping faucet waste per year?
- A.
  
  2,000 gallons
- B.
  
  100 gallons
- C.
  
  500 gallons
- D.
  
  25 gallons
Correct Answer
A. 2,000 gallons

Explanation
A dripping faucet wastes a significant amount of water over time. If we assume that the faucet drips at a rate of one drop per second, it would waste approximately 5 gallons of water per day, which adds up to 1,825 gallons per year. However, if the dripping rate is higher or the faucet is left unattended for longer periods, the amount of wasted water could be even higher. Therefore, the correct answer of 2,000 gallons accounts for these variables and represents a reasonable estimate of the water wasted by a dripping faucet in a year.

How long can a person live without water?
- A.
  
  1 month
- B.
  
  1 week
- C.
  
  1 year
- D.
  
  1 day
Correct Answer
B. 1 week

Explanation
A person can live without water for approximately 1 week. Water is essential for the body's normal functioning and dehydration can lead to severe health complications. The human body can only survive for a limited time without water as it is needed for various bodily functions such as digestion, circulation, and temperature regulation. Without an adequate water supply, the body becomes dehydrated, which can result in organ failure and ultimately death. Therefore, it is crucial to consume enough water to maintain proper hydration and ensure the body's survival.

How much water does one person use each day on average?
- A.
  
  25 gallons
- B.
  
  5 gallons
- C.
  
  Over 100 gallons
- D.
  
  2.5 gallons
Correct Answer
C. Over 100 gallons

Explanation
The average person uses over 100 gallons of water each day. This includes water used for drinking, cooking, bathing, flushing toilets, washing clothes, and other household activities. Additionally, water is also used indirectly in the production of food, goods, and services that we consume daily. Therefore, when considering both direct and indirect water usage, the amount of water used by an individual on a daily basis exceeds 100 gallons.

Typically, how much water is used to brush your teeth each day, without leaving the water running?
- A.
  
  Over 100 gallons
- B.
  
  25 gallons
- C.
  
  2 gallons
- D.
  
  1/2 gallon
Correct Answer
C. 2 gallons

Explanation
On average, brushing your teeth without leaving the water running uses approximately 2 gallons of water each day. This amount may vary depending on factors such as the duration of brushing and the type of toothbrush used. However, 2 gallons is a reasonable estimate for the amount of water typically used for this activity.

How much water is used to flush a toilet?
- A.
  
  1-3 gallons
- B.
  
  2-7 gallons
- C.
  
  20-25 gallons
- D.
  
  1 gallon
Correct Answer
B. 2-7 gallons

Explanation
The correct answer is 2-7 gallons. This is because older toilets typically use around 7 gallons of water per flush, while newer models are designed to be more water-efficient and use around 2 gallons. The amount of water used can also depend on factors such as the size of the toilet bowl and the type of flushing mechanism.

How much water is used in the average five-minute shower?
- A.
  
  15-25 gallons
- B.
  
  1-2 gallons
- C.
  
  5-7 gallons
- D.
  
  Over 100 gallons
Correct Answer
A. 15-25 gallons

Explanation
The average five-minute shower uses approximately 15-25 gallons of water. This is a reasonable range as it takes into account factors such as water pressure and flow rate. Showers typically use less water compared to other household activities such as washing clothes or dishes. However, it is important to be mindful of water consumption and consider ways to conserve water, such as using low-flow showerheads or taking shorter showers.

How many gallons of water would be contaminated by one gallon of gasoline?
- A.
  
  250 gallons

D. 750,000 gallons

Explanation
One gallon of gasoline can contaminate a large amount of water. The answer of 750,000 gallons suggests that the contamination caused by one gallon of gasoline can spread and affect a significant volume of water. This highlights the importance of preventing gasoline spills and properly managing and disposing of gasoline to protect the environment and water sources.
