How much of the water of the world can be used by humans?
- A.
10%
- B.
1%
- C.
50%
- D.
25%
Correct Answer
B. 1%Explanation
Only 1% of the water in the world is available for human use. The majority of the Earth's water is in the form of saltwater in the oceans, which is not suitable for drinking or irrigation. The remaining freshwater is mostly locked in ice caps, glaciers, and underground aquifers. This limited availability of usable water highlights the importance of conservation and sustainable water management practices to ensure a reliable supply for human needs.Rate this question:

Which city is the world's most polluted city?
- A.
Beijing
- B.
Mexico City
- C.
Los Angeles
- D.
New Delhi
Correct Answer
B. Mexico CityExplanation
Mexico City is often considered one of the most polluted cities in the world due to its high levels of air pollution. The city's geographical location, surrounded by mountains, traps pollutants and prevents them from dispersing. Additionally, Mexico City has a high population density and a large number of vehicles, which contribute to the pollution problem. Factors such as industrial emissions, construction activities, and the burning of fossil fuels also contribute to the city's poor air quality.Rate this question:

What is the name for a substance that can be broken down and eaten by microorganisms?
- A.
Biodegradable
- B.
Degradable
- C.
Recycled
- D.

Which one of the following is a renewable resource?
- A.
Wind
- B.
Coal
- C.
Oil
- D.
Gas
Correct Answer
A. WindExplanation
Wind is considered a renewable resource because it is naturally replenished and will not run out. Unlike coal, oil, and gas, which are finite resources formed over millions of years, wind energy is generated by the sun's heat and the Earth's rotation, making it an abundant and sustainable source of power. Harnessing wind energy through wind turbines allows us to convert it into electricity without depleting the wind itself, making it a cleaner and more environmentally friendly alternative to fossil fuels.Rate this question:

What is the greatest cause of carbon monoxide?
- A.
Motor vehicles
- B.
Jet planes
- C.
Farm animals
- D.
Ocean liners
Correct Answer
A. Motor vehiclesExplanation
Motor vehicles are the greatest cause of carbon monoxide because they emit this harmful gas as a byproduct of burning fossil fuels. The combustion process in engines releases carbon monoxide into the atmosphere, contributing to air pollution and posing health risks. Jet planes also emit carbon monoxide, but their overall impact is lower compared to motor vehicles. Farm animals and ocean liners do not release significant amounts of carbon monoxide into the environment.Rate this question:

How many of the world's inhabitants do not have access to clean water?
- A.
Over 40%
- B.
Over 15%
- C.
80%
- D.
Less than 30%
Correct Answer
A. Over 40%Explanation
Over 40% of the world's inhabitants do not have access to clean water. This means that a significant portion of the global population does not have access to safe and clean drinking water for their daily needs. Lack of access to clean water can lead to various health issues and can significantly impact the quality of life for those affected. It is a concerning statistic that highlights the need for efforts to improve access to clean water globally.Rate this question:

Which gas is mainly responsible for the green house effect?
- A.
CO2
- B.
O2
- C.
H2
- D.
Natural gas
Correct Answer
A. CO2Explanation
CO2, or carbon dioxide, is mainly responsible for the greenhouse effect. When released into the atmosphere through human activities such as burning fossil fuels, deforestation, and industrial processes, CO2 traps heat from the sun, causing the Earth's temperature to rise. This increase in temperature leads to climate change, with severe consequences such as melting ice caps, rising sea levels, and extreme weather events. Therefore, CO2 is a significant contributor to global warming and the greenhouse effect.Rate this question:

How much of our daily water consumption is used in the bathroom?
- A.
40%
- B.
75%
- C.
50%
- D.
15%
Correct Answer
B. 75%Explanation
Approximately 75% of our daily water consumption is used in the bathroom. This is because activities such as flushing the toilet, taking showers, and washing hands require a significant amount of water. Additionally, water is also used for activities like brushing teeth and shaving. Therefore, the bathroom is a major source of water usage in our daily lives.Rate this question:

What is the substance that protects humans from the sun's harmful rays?
- A.
Methane
- B.
Ozone
- C.
Propane
- D.
Hydrogen
Correct Answer
B. OzoneExplanation
Ozone is the substance that protects humans from the sun's harmful rays. Ozone is found in the Earth's atmosphere and acts as a shield, absorbing most of the sun's ultraviolet (UV) radiation. This prevents the UV rays from reaching the Earth's surface and causing damage to human skin, such as sunburns and skin cancer.Rate this question:

What do we call the process by which we use material more than once?
- A.
Recycling
- B.
Reusing
- C.
Repairing
- D.
Reviving
Correct Answer
A. RecyclingExplanation
Recycling is the process by which we use material more than once. It involves collecting and processing used materials such as paper, plastic, glass, and metal, and transforming them into new products. Recycling helps to conserve natural resources, reduce waste, and minimize the environmental impact of production and consumption. It is an important practice for sustainable living and plays a crucial role in mitigating climate change and preserving the planet for future generations.Rate this question:

How much of the garbage in the ocean is plastic?
- A.
70%
- B.
90%
- C.
50%
- D.
10%
Correct Answer
B. 90%Explanation
The correct answer is 90% because plastic pollution is a major issue in the world's oceans. It is estimated that 90% of the garbage in the ocean is made up of plastic. This is due to the widespread use of single-use plastics and improper waste management practices. Plastic debris poses a significant threat to marine life and ecosystems, as it can be ingested by animals or entangle them, causing harm and even death. Efforts to reduce plastic consumption and improve waste management are crucial to addressing this problem.Rate this question:

How many trees does every tonne of recycled paper save?
- A.
118 trees
- B.
17 trees
- C.
100 trees
- D.
10 trees
Correct Answer
B. 17 treesExplanation
Every tonne of recycled paper saves 17 trees. This is because when paper is recycled, it reduces the need for new paper production, which in turn reduces the number of trees that need to be cut down for paper production. Recycling paper helps to conserve forests and protect the environment.Rate this question:

How long does it take glass to decompose?
- A.
1 million years
- B.
500 years
- C.
1 year
- D.
We don't know
Correct Answer
A. 1 million yearsExplanation
Glass is made from sand, soda ash, and limestone, which are heated at high temperatures to form a solid. Unlike organic materials, glass does not decompose naturally through biological processes. It is highly resistant to environmental factors such as moisture and sunlight, which slows down its breakdown. It is estimated that it takes approximately 1 million years for glass to decompose completely.Rate this question:

What do we call rain that contains chemical waste and damages plants and animals?
- A.
Heavy rain
- B.
Acid rain
- C.
Methane rain
- D.
Polluted rain
Correct Answer
B. Acid rainExplanation
Acid rain is the correct answer because it refers to rainwater that contains harmful pollutants, such as sulfur dioxide and nitrogen oxide, which react with the atmosphere and form sulfuric acid and nitric acid. These acids can cause damage to plants, animals, and infrastructure. Acid rain is a significant environmental issue that is primarily caused by human activities, such as burning fossil fuels and industrial emissions.Rate this question:
