What Is The Worst Environmental Problem In Your Opinion?

2.

What country is the highest producer of carbon dioxide in 2007?

Spain
China
United States
Russia

Correct Answer

A. 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.

What can be used in treatment of contaminated water?

Camphor
Liquid Ammonia
Ethene
Chlorine

Correct Answer

A. 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.

Most air pollution is caused by _________

Nuclear waste disposal activities
Human sewage
Transport vehicles emmisions
Factories wastes

Correct Answer

A. 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.

The following are remedies to global warming except?

Climate engineering
Increased activities on water bodies
Adaptation to effects of global warming
Mitigation by emissions reductions

Correct Answer

A. 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.

Which of these dies not contribute to global warming?

Biofuels
Soot
Fossil fuels
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.

8.

The following are effects of global warming except

Changing precipitation
Increased natural disasters
Rising sea levels
Increasing global temperatures

Correct Answer

A. 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.

These are the main factors that determine the severity of a pollutant except

Persistence
Chemistry
Physical nature
Concentration

Correct Answer

A. 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.

10.

All of the following are examples of visual pollution save except

Presence of Alpha emitters
Presence of space debris
Scarred landform
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.
