Questions and Answers
- 1.
What did you understand after watching the short movie? Think of some daily life situations where pollution is caused, what can we do to reduce pollution and environment degradation?
- 2.
What causes pollution?
- A.
Cars
- B.
Animals
- C.
Factories
- D.
Both A and C
Correct Answer
D. Both A and CExplanation
Both cars and factories are major contributors to pollution. Cars emit pollutants such as carbon dioxide, nitrogen oxides, and particulate matter, which contribute to air pollution. Factories release various pollutants into the air, water, and soil, including toxic chemicals and greenhouse gases. Therefore, both A (cars) and C (factories) are correct answers for what causes pollution. Animals, on the other hand, do not significantly contribute to pollution compared to cars and factories.Rate this question:

The concentration of which gas is highest in our environment?
- A.
Oxygen
- B.
Nitrogen
- C.
Hydrogen
- D.
Carbon di-oxide
Correct Answer
B. NitrogenExplanation
Nitrogen is the most abundant gas in our environment, making up approximately 78% of the Earth's atmosphere. It is found in the air we breathe and is essential for various biological processes. Oxygen, hydrogen, and carbon dioxide are also present in the atmosphere, but in much lower concentrations compared to nitrogen.Rate this question:

Which of the following is NOT one of the 3 "R"s of recycling?
- A.
Reduce
- B.
Reuse
- C.
Reverse
- D.
Recycle
Correct Answer
C. ReverseExplanation
The correct answer is "Reverse" because it is not one of the three "R"s of recycling. The three "R"s of recycling are "Reduce," "Reuse," and "Recycle." "Reverse" does not fit into this category and is therefore not one of the three main principles of recycling.Rate this question:

What odorless gas is produced by cars and can even lead to death if inhaled in excess?
- A.
Carbon di-oxide
- B.
Carbon monoxide
- C.
Sulphur dioxide
- D.
Chloro Flouro Carbon
Correct Answer
B. Carbon monoxideExplanation
Carbon monoxide is an odorless gas that is produced by cars. It is a highly toxic gas that can lead to death if inhaled in excess. Carbon monoxide is produced as a result of incomplete combustion of fossil fuels, such as gasoline, in car engines. It is important to have proper ventilation in enclosed spaces and to avoid inhaling carbon monoxide to prevent its harmful effects.Rate this question:

What type of water pollution can occur when sulfur dioxide gets into the Earth's atmosphere?
- A.
Acid Rain
- B.
Algal Bloom
- C.
Oxygen depletion
- D.
Sewage pollution
Correct Answer
A. Acid RainExplanation
Sulfur dioxide is a pollutant that can be released into the atmosphere through industrial processes, volcanic eruptions, and burning of fossil fuels. When sulfur dioxide reacts with water in the atmosphere, it forms sulfuric acid, which then falls to the ground as acid rain. Acid rain can have harmful effects on the environment, including damaging plants, forests, and aquatic ecosystems. Therefore, the correct answer is Acid Rain.Rate this question:

True or False: Many people on Earth do not have access to clean water.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Many people on Earth do not have access to clean water. This is a well-known fact supported by various studies and reports. Lack of access to clean water is a significant issue in many developing countries, leading to numerous health problems, including waterborne diseases. Insufficient infrastructure, poverty, and environmental factors contribute to the limited availability of clean water in certain regions. Therefore, the statement "Many people on Earth do not have access to clean water" is true.Rate this question:

Around how much of the Earth's water is fresh water?
- A.
1%
- B.
10%
- C.
5%
- D.
20%
Correct Answer
A. 1%Explanation
Approximately 1% of the Earth's water is fresh water. This means that only a small fraction of the total water on our planet is available for human use, such as drinking, agriculture, and sanitation. The majority of the Earth's water is saltwater, found in the oceans, which is not suitable for consumption or most human activities. Freshwater resources are vital for sustaining life and are a limited and precious resource that needs to be conserved and managed carefully.Rate this question:

How can land pollution harm the environment?
- A.
It can destroy the habitats of animals
- B.
It causes harmful chemicals to enter the soil
- C.
It can destroy the beauty of nature
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Land pollution can harm the environment in multiple ways. Firstly, it can destroy the habitats of animals, leading to a loss of biodiversity. Secondly, it causes harmful chemicals to enter the soil, which can contaminate groundwater and affect the health of plants, animals, and humans. Lastly, it can destroy the beauty of nature by turning once pristine landscapes into polluted and unsightly areas. Therefore, all of the above options are correct explanations of how land pollution can harm the environment.Rate this question:

What do we call large areas where garbage is placed on the land?
- A.
Landfills
- B.
Mines
- C.
Garbagelands
- D.
Trashlands
Correct Answer
A. LandfillsExplanation
Large areas where garbage is placed on the land are called landfills. This is where waste materials are disposed of and buried in the ground. Landfills are designed to minimize the environmental impact of waste disposal by using methods to prevent contamination of soil and water. They are an essential part of waste management systems in many countries.Rate this question:

What is it called when you collect organic waste and store it so it breaks down into fertilizer?
- A.
Composting
- B.
Recycling
- C.
Global Warming
- D.
Trashing
Correct Answer
A. CompostingExplanation
Composting is the process of collecting organic waste and storing it in a controlled environment so that it can decompose and turn into nutrient-rich fertilizer. This process involves the natural breakdown of organic materials by microorganisms, such as bacteria and fungi, which convert the waste into a valuable soil amendment. Composting is an environmentally friendly practice that helps reduce waste, improve soil health, and promote sustainable gardening and agriculture.Rate this question:

Around how long does it take Styrofoam to decay and become part of the environment?
- A.
2 years
- B.
6 months
- C.
10 years
- D.
It never decomposes fully
Correct Answer
D. It never decomposes fullyExplanation
Styrofoam, also known as expanded polystyrene, is a synthetic material that is not biodegradable. This means that it does not break down naturally over time like organic materials. Instead, Styrofoam remains in the environment indefinitely, taking up space in landfills or polluting ecosystems. It can be broken down into smaller pieces due to physical processes such as weathering or mechanical action, but it never fully decomposes into its original components. Therefore, the correct answer is that Styrofoam never decomposes fully.Rate this question:

Which pollution cause hearing loss in organisms?
- A.
Air Pollution
- B.
Noise Pollution
- C.
Water Pollution
- D.
Land Pollution
Correct Answer
B. Noise PollutionExplanation
Exposure to excessive noise pollution can cause hearing loss in organisms. Prolonged exposure to loud noises can damage the delicate structures of the inner ear, leading to permanent hearing loss. This can affect both humans and animals, disrupting their ability to communicate, navigate, and detect potential dangers in their environment. Noise pollution can come from various sources such as traffic, construction sites, industrial activities, and loud music. It is important to regulate and control noise levels to protect the health and well-being of both humans and other organisms.Rate this question:

Effects produced by excessive noise are
- A.
Hearing loss
- B.
Migraine headaches
- C.
Hypertension
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Excessive noise can have various negative effects on our health. It can lead to hearing loss by damaging the sensitive structures in our ears. Additionally, it can trigger migraine headaches in individuals who are sensitive to loud sounds. Moreover, prolonged exposure to loud noise can also cause hypertension or high blood pressure. Therefore, all of the mentioned effects, including hearing loss, migraine headaches, and hypertension, can be produced by excessive noise.Rate this question:
