Which of the following is an example of using filtration?
- A.
Filling a balloon with air
- B.
Boiling a pot of water
- C.
Making coffee by pouring water over coffee grounds
- D.
Freezing water to make ice
Correct Answer
C. Making coffee by pouring water over coffee groundsExplanation
Making coffee by pouring water over coffee grounds is an example of using filtration because the water passes through the coffee grounds, allowing the liquid to separate from the solid particles. Filtration is a process that separates a mixture by passing it through a medium that retains the solid particles while allowing the liquid or gas to pass through. In this case, the coffee grounds act as the filter, allowing the liquid coffee to be collected while trapping the solid coffee grounds.Rate this question:

What is used to gather water from lakes, rivers and streams then send it to a water treatment plant?
- A.
A garden hose
- B.
A water slide
- C.
A pumping station
- D.
A tube
Correct Answer
C. A pumping stationExplanation
A pumping station is used to gather water from lakes, rivers, and streams and then send it to a water treatment plant. It is designed to pump large volumes of water over long distances, using pumps and pipes. The pumping station helps to transport water efficiently and effectively from the natural water sources to the treatment plant, where it can be purified and made safe for consumption.Rate this question:

Why does water go through a water treatment plant?
- A.
It is the natural route to where the water flows
- B.
To divide it into separate portions for different houses
- C.
To cool it down
- D.
To make it safe to drink
Correct Answer
D. To make it safe to drinkExplanation
Water goes through a water treatment plant to make it safe to drink. The treatment process involves removing impurities, such as bacteria, viruses, chemicals, and pollutants, from the water. This is done through various methods like filtration, disinfection, and chemical treatment. Ensuring that the water is safe to drink is crucial for public health, as contaminated water can lead to the spread of diseases. Therefore, water treatment plants play a vital role in providing clean and safe drinking water to communities.Rate this question:

Where does water come from before it reaches your house?
- A.
The hospital
- B.
The park
- C.
A treatment plant
Correct Answer
C. A treatment plantExplanation
Water comes from a treatment plant before it reaches your house. Treatment plants are responsible for purifying and treating water from various sources such as rivers, lakes, and underground reservoirs. They remove impurities, bacteria, and contaminants through processes like filtration, disinfection, and chemical treatment. This ensures that the water is safe for consumption and use in households. After the treatment process, the water is then distributed through a network of pipes to reach individual homes and buildings.Rate this question:

What must some cities/towns do to get water?
- A.
Borrow it from nearby towns
- B.
Buy or import it from other countries
- C.
Provide people with barrels and buckets to catch rainwater
- D.
Make factories to process seawater
Correct Answer(s)
B. Buy or import it from other countries
D. Make factories to process seawaterExplanation
Some cities/towns must buy or import water from other countries in order to meet their water needs. This could be due to a scarcity of water resources in their own region. Additionally, some cities/towns may also need to make factories to process seawater, as desalination can provide a source of freshwater in coastal areas where seawater is abundant but freshwater is scarce.Rate this question:

What percent of the Earth's water is found in oceans?
- A.
50%
- B.
97%
- C.
85%
- D.
75%
Correct Answer
B. 97%Explanation
97% of the Earth's water is found in oceans. This is because the oceans cover a vast majority of the Earth's surface, and they contain a significant amount of water in the form of saltwater. The remaining 3% of the Earth's water is found in other sources such as glaciers, lakes, rivers, and groundwater.Rate this question:

What percent of the Earth's water is permanently frozen in glaciers and ice caps?
- A.
2.4
- B.
3
- C.
4.2
- D.
1
Correct Answer
A. 2.4Explanation
Approximately 2.4 percent of the Earth's water is permanently frozen in glaciers and ice caps. This frozen water plays a vital role in regulating global climate and sea levels. It also serves as a freshwater reserve for many regions, as it slowly melts and releases water into rivers and lakes.Rate this question:

Which of the following would you not use to filter a liquid?
- A.
Coffee filter
- B.
Gravel
- C.
Charcoal
- D.
Mud
Correct Answer
D. MudExplanation
Mud is not used to filter a liquid because it contains solid particles and impurities that can further contaminate the liquid. Coffee filters are commonly used to remove small particles and sediments from liquids like coffee or tea. Gravel can be used as a coarse filter to remove larger particles from liquids. Charcoal is often used as an absorbent material to remove impurities and odors from liquids. However, mud is not suitable for filtration purposes as it will not effectively separate the liquid from solid particles.Rate this question:
