What Is The Worst Environmental Problem In Your Opinion? - Quiz

Environmental problems like global warming, pollution and climate change are serious issues on which world leaders are concerned. Most of the environmental abnomalties are triggered by human activities. While the effect can be widespread, it is usually not short-lived. Get acquainted with causes and examples of environmental problem in this quiz.

Questions and Answers

1.

Which of the following is not a greenhouse gas?
- A.
  
  Ammonia
- B.
  
  Nitrous Oxide
- C.
  
  Methane
- D.
  
  Carbon dioxide
Correct Answer
A. Ammonia

Explanation
Ammonia is not considered a greenhouse gas because it does not have the ability to trap heat in the atmosphere like the other options listed. Greenhouse gases, such as nitrous oxide, methane, and carbon dioxide, have the property of absorbing and emitting infrared radiation, which leads to the greenhouse effect and contributes to global warming. Ammonia, on the other hand, is not a significant contributor to the greenhouse effect and is not classified as a greenhouse gas.

2.

The following are effects of global warming except
- A.
  
  Changing precipitation
- B.
  
  Increased natural disasters
- C.
  
  Rising sea levels
- D.
  
  Increasing global temperatures
Correct Answer
B. Increased natural disasters

Explanation
Global warming refers to the long-term increase in Earth's average temperature, primarily caused by the release of greenhouse gases from human activities. It leads to various effects such as changing precipitation patterns, rising sea levels, and increasing global temperatures. However, increased natural disasters cannot be directly attributed to global warming. While climate change may influence the frequency and intensity of some extreme weather events, it is not the sole cause of natural disasters like earthquakes or volcanic eruptions. Therefore, increased natural disasters are not considered an effect of global warming.

3.

The following are remedies to global warming except?
- A.
  
  Climate engineering
- B.
  
  Increased activities on water bodies
- C.
  
  Adaptation to effects of global warming
- D.
  
  Mitigation by emissions reductions
Correct Answer
B. Increased activities on water bodies

Explanation
Increased activities on water bodies is not a remedy to global warming because it does not directly address the root causes or help to reduce greenhouse gas emissions. Climate engineering, adaptation to effects of global warming, and mitigation by emissions reductions are all strategies aimed at combating global warming. Climate engineering involves manipulating the Earth's climate system to counteract the effects of global warming. Adaptation involves adjusting to the changes caused by global warming. Mitigation focuses on reducing greenhouse gas emissions to prevent further warming of the planet.

When was the concept of greenhouse effects proposed?
- A.
  
  1822
- B.
  
  1824
- C.
  
  1719
- D.
  
  1724
Correct Answer
B. 1824

Explanation
The concept of greenhouse effects was proposed in 1824.

5.

Which of these dies not contribute to global warming?
- A.
  
  Biofuels
- B.
  
  Soot
- C.
  
  Fossil fuels
- D.
  
  Black carbon
Correct Answer
A. Biofuels

Explanation
Biofuels do not contribute to global warming because they are derived from renewable sources such as plants and crops. When these fuels are burned, they release carbon dioxide, but since the plants used to make them absorb carbon dioxide during their growth, the overall carbon footprint is considered neutral. On the other hand, soot, fossil fuels, and black carbon all release greenhouse gases and contribute to global warming.

6.

All of the following are examples of visual pollution save except
- A.
  
  Presence of Alpha emitters
- B.
  
  Presence of space debris
- C.
  
  Scarred landform
- D.
  
  Presence of overhead power lines
Correct Answer
A. Presence of Alpha emitters

Explanation
Visual pollution refers to the presence of man-made elements that are visually unappealing or disturbing in the environment. Examples of visual pollution include scarred landforms, presence of space debris, and presence of overhead power lines. However, the presence of Alpha emitters does not contribute to visual pollution as they are not visible to the naked eye. Alpha emitters are radioactive particles that can be harmful to human health, but they do not have a direct visual impact on the environment.

7.

What can be used in treatment of contaminated water?
- A.
  
  Camphor
- B.
  
  Liquid Ammonia
- C.
  
  Ethene
- D.
  
  Chlorine
Correct Answer
D. Chlorine

Explanation
Chlorine can be used in the treatment of contaminated water. Chlorine is a powerful disinfectant that can kill bacteria, viruses, and other harmful microorganisms present in water. It is commonly used in water treatment plants to ensure that the water is safe for consumption. Chlorine works by breaking down the cell walls of microorganisms, effectively killing them and making the water safe to drink. It is a widely used and effective method for water purification.

8.

These are the main factors that determine the severity of a pollutant except
- A.
  
  Persistence
- B.
  
  Chemistry
- C.
  
  Physical nature
- D.
  
  Concentration
Correct Answer
C. Physical nature

Explanation
The severity of a pollutant is determined by factors such as persistence, chemistry, and concentration. Persistence refers to how long the pollutant remains in the environment, while chemistry refers to its chemical properties and reactions. Concentration refers to the amount of the pollutant present. However, the physical nature of the pollutant, such as its size or shape, does not directly determine its severity.

Most air pollution is caused by _________
- A.
  
  Nuclear waste disposal activities
- B.
  
  Human sewage
- C.
  
  Transport vehicles emmisions
- D.
  
  Factories wastes
Correct Answer
C. Transport vehicles emmisions

Explanation
Transport vehicles emissions are a major contributor to air pollution. The burning of fossil fuels in cars, trucks, and other vehicles releases pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the air. These pollutants can have harmful effects on human health and the environment, leading to respiratory problems, smog formation, and climate change. Therefore, transport vehicles emissions are a significant source of air pollution.

What country is the highest producer of carbon dioxide in 2007?
- A.
  
  Spain
- B.
  
  China
- C.
  
  United States
- D.
  
  Russia
Correct Answer
B. China

Explanation
China is the correct answer because it was the highest producer of carbon dioxide in 2007. This is likely due to China's rapid industrialization and extensive use of coal for energy production during that time.
