Questions and Answers
- 1.
Global warming is cause only by natural factors.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because global warming is not solely caused by natural factors. Human activities, such as the burning of fossil fuels and deforestation, contribute significantly to the increase in greenhouse gases, which in turn leads to global warming. While natural factors like volcanic eruptions and solar radiation can also influence the Earth's climate, they do not account for the current rapid warming trend observed in recent decades.Rate this question:

Which country currently emits the most greenhouse gases?
- A.
India
- B.
China
- C.
The United Kingdom
- D.
The United States
Correct Answer
B. ChinaExplanation
China is currently the country that emits the most greenhouse gases. This is due to its large population and rapid industrialization over the past few decades. China is the world's largest producer and consumer of coal, which is a major source of greenhouse gas emissions. Additionally, its manufacturing sector is responsible for a significant amount of greenhouse gas emissions. Despite efforts to reduce emissions, China's reliance on coal and its growing economy continue to contribute to its high greenhouse gas emissions.Rate this question:

Which planet's poisonous atmosphere has been describes as the product of a "runaway greenhouse effect"?
- A.
Earth
- B.
Mars
- C.
Venus
- D.
Jupiter
Correct Answer
C. VenusExplanation
Venus has a poisonous atmosphere that has been described as the product of a "runaway greenhouse effect". This means that the planet's atmosphere traps heat from the sun, causing the temperature to rise to extreme levels. The high temperatures on Venus cause the carbon dioxide in the atmosphere to increase, creating a thick layer that traps even more heat. This process continues in a cycle, creating a greenhouse effect that makes Venus' atmosphere inhospitable and poisonous.Rate this question:

Which of the following light bulb types uses the least energy, and therefore results in fewer greenhouse gas emissions?
- A.
Incandescent
- B.
Compact fluorescent
- C.
Halogen
Correct Answer
B. Compact fluorescentExplanation
Compact fluorescent light bulbs use the least energy compared to incandescent and halogen bulbs. This is because compact fluorescent bulbs use up to 75% less energy to produce the same amount of light as incandescent bulbs. By using less energy, compact fluorescent bulbs also result in fewer greenhouse gas emissions, making them a more environmentally friendly option.Rate this question:

How many human deaths per year does the World Health Organization attribute to climate change?
- A.
150,000
- B.
1,500
- C.
1,500,000
- D.
10,500
Correct Answer
A. 150,000Explanation
The World Health Organization attributes 150,000 human deaths per year to climate change.Rate this question:

How long does it take for carbon dioxide in the atmosphere to dispense?
- A.
1 year
- B.
10 years
- C.
50 years
- D.
100 years
Correct Answer
D. 100 yearsExplanation
Carbon dioxide in the atmosphere takes approximately 100 years to disperse. This is because carbon dioxide is a greenhouse gas that can remain in the atmosphere for a long time, contributing to the greenhouse effect and climate change. The dispersal process involves various factors such as natural processes like photosynthesis and the absorption of carbon dioxide by oceans, as well as human activities like deforestation and burning fossil fuels. These factors collectively determine the time it takes for carbon dioxide to disperse from the atmosphere.Rate this question:

Which Arctic animal do many scientists consider most vulnerable to extinction due to global warming?
- A.
Toucans
- B.
Tropical frogs
- C.
Polar Bears
- D.
Narwhals
Correct Answer
D. NarwhalsExplanation
Narwhals are considered the most vulnerable to extinction due to global warming by many scientists. This is because they rely on sea ice for feeding and breeding, and as the Arctic sea ice melts, their habitat is shrinking. The loss of sea ice also affects their prey, such as fish and shrimp, making it harder for narwhals to find food. Additionally, the warming temperatures may disrupt their migration patterns and increase the risk of predation. Therefore, the combination of habitat loss, food scarcity, and disrupted behavior patterns makes narwhals highly vulnerable to extinction.Rate this question:

Global warming is accelerated by the reduction of global snow and ice cover.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The reduction of global snow and ice cover contributes to global warming because snow and ice reflect sunlight back into space, helping to cool the Earth's surface. When the snow and ice melt, more of the sun's energy is absorbed by the darker surfaces, such as land and water, leading to increased warming. This phenomenon is known as the albedo effect. Therefore, the statement that global warming is accelerated by the reduction of global snow and ice cover is true.Rate this question:

During what time of the day does air travel have the least damaging effect on the environment?
- A.
Daytime
- B.
Nighttime
- C.
They are equally damaging
Correct Answer
C. They are equally damagingExplanation
Air travel has a damaging effect on the environment regardless of the time of day. The emissions from aircraft contribute to air pollution, greenhouse gas emissions, and noise pollution. These negative impacts occur regardless of whether it is daytime or nighttime. Therefore, both daytime and nighttime air travel have an equally damaging effect on the environment.Rate this question:

Which of the following industries could be negatively affected by global warming?
- A.
Insurance
- B.
Commercial Fishing
- C.
Wine making
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Global warming can negatively affect the insurance industry as it leads to an increase in extreme weather events, such as hurricanes and floods, which result in higher insurance claims. Commercial fishing can be negatively affected as global warming leads to changes in ocean temperatures and currents, affecting fish populations and their habitats. Wine making can also be negatively affected as rising temperatures can impact grape production and quality. Therefore, all of the industries mentioned could be negatively affected by global warming.Rate this question:
