Questions and Answers
- 1.
What causes pollution?
- A.
Cars
- B.
Animals
- C.
Factories
- D.
A and C only
Correct Answer
D. A and C onlyExplanation
Cars and factories are both 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 greenhouse gases, toxic chemicals, and industrial waste. Animals, on the other hand, do not directly cause pollution on a large scale. While animal agriculture can contribute to pollution through the release of methane and other greenhouse gases, it is not mentioned as a separate option in this question. Therefore, the correct answer is A and C only.Rate this question:

Which of the following pollutants can damage lungs?
- A.
Ozone
- B.
Smog
- C.
Carbon dioxide
- D.
Nitrogen
Correct Answer
B. SmogExplanation
Smog is a mixture of pollutants, including ozone and nitrogen compounds, that can cause damage to the lungs. When inhaled, smog particles can irritate the respiratory system, leading to inflammation and various respiratory problems. Smog is particularly harmful to individuals with pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). Carbon dioxide, on the other hand, is not considered a direct lung pollutant as it is a natural component of the atmosphere.Rate this question:

Which of the following gases does an automobile produce?
- A.
Carbon dioxide
- B.
Nitrogen
- C.
Helium
- D.
Carbon monoxide
Correct Answer
D. Carbon monoxideExplanation
Automobiles produce carbon monoxide as one of the gases. Carbon monoxide is a colorless and odorless gas that is released from the exhaust of vehicles. It is produced when fuel is not completely burned in the engine. Carbon monoxide is toxic and can be harmful to humans and the environment.Rate this question:

This type of pollutant causes acidification of rivers, lakes and also damages tree foliage and degrades soil quality.
- A.
Ozone Layer
- B.
Acid rain
- C.
Oil
- D.
None of the above
Correct Answer
B. Acid rainExplanation
Acid rain is the correct answer because it is a type of pollutant that causes acidification of rivers, lakes, damages tree foliage, and degrades soil quality. Acid rain occurs when emissions from burning fossil fuels react with the atmosphere and form sulfuric and nitric acids. These acids then fall to the earth as rain, snow, or fog, causing harm to the environment.Rate this question:

When burning fuel for energy, small particles are thrown into the air that are visible in the form of smoke. It is called this type of pollution.
- A.
Black carbon pollution
- B.
Indoor pollution
- C.
Outdoor pollution
- D.
Air pollution
Correct Answer
A. Black carbon pollutionExplanation
When fuel is burned for energy, it releases small particles into the air that can be seen as smoke. This type of pollution is specifically referred to as black carbon pollution. Black carbon particles are produced by the incomplete combustion of fossil fuels, biomass, and biofuels. These particles can have a significant impact on air quality and climate change, as they absorb sunlight and contribute to the warming of the atmosphere. Therefore, black carbon pollution is a form of air pollution caused by the burning of fuel.Rate this question:

The average temperature around the world has climbed during the previous century due to global warming by this much.
- A.
2 degrees Fahrenheit
- B.
1 degree Fahrenheit
- C.
3 degree Fahrenheit
- D.
4 degree Fahrenheit
Correct Answer
B. 1 degree FahrenheitExplanation
The correct answer is 1 degree Fahrenheit. This means that on average, the temperature around the world has increased by 1 degree Fahrenheit over the previous century due to global warming.Rate this question:

Which of the following substances is harmful to water?
- A.
Carbon dioxide
- B.
Salt
- C.
Hydrogen
- D.
Oil
Correct Answer
D. OilExplanation
Oil is harmful to water because it is insoluble and forms a thin layer on the surface of water, preventing oxygen from entering the water and suffocating aquatic organisms. Additionally, oil can contain toxic chemicals and pollutants that can contaminate the water and harm marine life.Rate this question:

Which of the following is ozone not used for?
- A.
Bleach
- B.
Softening clothes
- C.
Sterilizing water
- D.
All of the above
Correct Answer
A. BleachExplanation
Ozone is not used for bleaching. Ozone is commonly used for softening clothes and sterilizing water due to its strong oxidizing properties. It is a powerful disinfectant and can effectively kill bacteria and viruses in water. However, ozone does not have bleaching properties and is not typically used for this purpose.Rate this question:

The ozone found in the lowest layer of the atmosphere is often called "bad ozone." What is the name of this atmospheric layer?
- A.
stratosphere
- B.
Troposphere
- C.
Mesosphere
- D.
Intersphere
Correct Answer
B. TroposphereExplanation
The correct answer is troposphere. The troposphere is the lowest layer of the atmosphere where weather occurs. It is where the majority of Earth's ozone is found. The ozone in the troposphere is considered "bad ozone" because it is a pollutant that can cause respiratory issues and contribute to smog. The stratosphere, mesosphere, and intersphere are other layers of the atmosphere, but they do not contain as much ozone as the troposphere.Rate this question:

Ozone pollution is worst at what time of day?
- A.
Afternoon
- B.
Early evening
- C.
A and B only
- D.
Nighttime
Correct Answer
C. A and B onlyExplanation
Ozone pollution is worst during the afternoon and early evening. This is because sunlight and heat promote the formation of ozone. In the afternoon, the sunlight is strongest, causing the pollutants to react and form ozone. As the day progresses into the early evening, the temperature remains high, allowing for continued ozone formation. During nighttime, the lack of sunlight and lower temperatures prevent the formation of ozone, making it less prevalent compared to the afternoon and early evening.Rate this question:

The Air Quality Index (AQI) measures which of the following?
- A.
Carbon dioxide
- B.
Particulate matter
- C.
Ultraviolet radiation
- D.
All of the above
Correct Answer
B. Particulate matterExplanation
The Air Quality Index (AQI) measures the level of particulate matter in the air. Particulate matter refers to tiny particles and droplets that are suspended in the air, such as dust, smoke, pollen, and soot. These particles can be harmful to human health when inhaled, especially those that are smaller in size and can penetrate deep into the lungs. Monitoring and measuring the level of particulate matter in the air helps to assess and communicate the air quality to the public, and to take appropriate actions to protect human health and the environment.Rate this question:

Which of the following is not a symptom of ozone exposure?
- A.
Chest Pains
- B.
Naseua
- C.
Coughing
- D.
Sore throat
Correct Answer
B. NaseuaExplanation
Nausea is not a symptom of ozone exposure. Ozone exposure can cause chest pains, coughing, and a sore throat. Nausea is typically not associated with ozone exposure and may indicate a different health issue.Rate this question:

In the last several years, the level of many air pollutants has:
- A.
Increased
- B.
Decreased
- C.
Stayed the same
- D.
Hasn`t changed
Correct Answer
B. DecreasedExplanation
The correct answer is "Decreased". This means that in the last several years, the level of many air pollutants has gone down. This could be due to various factors such as stricter regulations on emissions, increased use of clean energy sources, and improved technology in industries. The decrease in air pollutants is a positive trend as it indicates progress in environmental protection and efforts to improve air quality.Rate this question:

"Good ozone" is found in what layer of the atmosphere?
- A.
Troposhphere
- B.
Mesosphere
- C.
Stratosphere
- D.
None of the above
Correct Answer
C. StratosphereExplanation
Good ozone, also known as ozone layer, is found in the stratosphere. The stratosphere is the second layer of the Earth's atmosphere, located above the troposphere. The ozone layer plays a crucial role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation. It acts as a shield against UV-B and UV-C rays, which can cause skin cancer, cataracts, and other harmful effects on both humans and the environment.Rate this question:
