Mainly by natural factors.
- D.
Both by human and natural factors.
Correct Answer
D. Both by human and natural factors.Explanation
Both natural and human factors contribute to the changes of the Earth's climate. According to the U.S. Geological Survey (USGS), the world’s volcanoes generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes comprise less than one percent of those generated by today’s human endeavors.Rate this question:

During the 150 years of the industrial age, the atmospheric concentration of carbon dioxide has increased by ...
- A.
31 %
- B.
45%
- C.
58%
- D.
67%
Correct Answer
A. 31 %Explanation
During the 150 years of the industrial age, the atmospheric concentration of carbon dioxide has increased by 31%. This increase can be attributed to various human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change. The 31% increase in carbon dioxide concentration highlights the significant impact of human activities on the Earth's atmosphere and the urgent need for sustainable practices to mitigate further increases.Rate this question:

Which of the following is the largest contributor to global greenhouse gas emissions?
- A.
Deforestation
- B.
Industrial processes
- C.
Agriculture
- D.
Energy production
Correct Answer
D. Energy productionExplanation
Energy production is the largest source of global greenhouse gas emissions, contributing over 70% of the total emissions. This includes the burning of fossil fuels (coal, oil, and natural gas) for electricity and heat, which releases significant amounts of carbon dioxide (CO₂) and other greenhouse gases. Deforestation and agriculture are also major contributors, but their impact is smaller compared to energy production. Industrial processes release greenhouse gases as well, but again, the emissions from energy production surpass all other sectors, making it the leading contributor to climate change.Rate this question:

Global warming may ...
- A.
Influence the length of seasons.
- B.
Cause coastal flooding.
- C.
Lead to more frequent and severe storms.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
As the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This increase in trapped heat changes the climate and alters weather patterns.Rate this question:

To create just 1 kilogram of consumer goods, manufacturers create ... kilograms of waste.
- A.
1
- B.
3
- C.
5
- D.
7
Correct Answer
C. 5Explanation
To create just 1 kilogram of consumer goods, manufacturers create 5 kilograms of waste. This means that for every unit of consumer goods produced, there is a significant amount of waste generated. This waste could be in the form of byproducts, packaging materials, or other types of waste generated during the manufacturing process. The high ratio of waste to consumer goods highlights the environmental impact and inefficiency of the manufacturing process.Rate this question:

Rainforests once covered 14% of the earth's land surface; now they cover ....
- A.
6%
- B.
8%
- C.
10%
- D.
12%
Correct Answer
A. 6%Explanation
The correct answer is 6%. This suggests that rainforests have significantly decreased in coverage over time, from 14% to just 6% of the earth's land surface. This decline in rainforest coverage is a result of deforestation, climate change, and human activities such as logging and agriculture. The loss of rainforests is concerning because they are vital ecosystems that support a wide variety of plant and animal species, as well as provide important ecological services such as carbon sequestration and regulation of the water cycle.Rate this question:
-

... plant, animal and insect species are being lost every single day due to rainforest deforestation.
- A.
100
- B.
137
- C.
168
- D.
More than 200
Correct Answer
B. 137Explanation
The statement mentions that plant, animal, and insect species are being lost every single day due to rainforest deforestation. The answer "137" implies that 137 species are being lost every day. This number is within the given range of options and is a plausible estimate considering the extent of rainforest deforestation and its impact on biodiversity.Rate this question:

What is the most common type of trash thrown away by Americans?
- A.
Paper products and cardboards
- B.
Plastic bags
- C.
Metal
- D.
Glass bottles
Correct Answer
A. Paper products and cardboardsExplanation
According to recent studies and waste management reports, paper products and cardboard are the most common types of trash generated by Americans. These materials make up a significant portion of municipal solid waste, which includes items like packaging, newspapers, magazines, mail, food and beverage containers, and more.The reason for this is that paper products are widely used in various aspects of daily life, including packaging, printing, and food service. Additionally, cardboard is commonly used in product shipping and retail displays.While other materials like plastic bags, metal, and glass bottles are also frequently thrown away, they do not compare to the sheer volume of paper and cardboard waste generated in the United States.Rate this question:

Most of the oil that we use is imported into our country from other nations. The oil is carried in huge sea-going tankers. Sometimes, these tankers get damaged, and the oil leaks into the oceans and seas. What is such an accidental discharge of oil into water bodies called?
- A.
Water pollution
- B.
Oil leak
- C.
Oil spill
- D.
Tanker leak
Correct Answer
C. Oil spillExplanation
Oil on ocean surfaces, which is called an oil spill, is harmful to many forms of aquatic life because it prevents sufficient amounts of sunlight from penetrating and also reduces the level of oxygen dissolved in seawater. Crude oil renders feathers and gills ineffective, so that birds and fish may die from direct contact with the oil itself.Rate this question:

Which of the following greenhouse gases is primarily responsible for trapping heat in the Earth's atmosphere?
- A.
Carbon dioxide (CO2)
- B.
Nitrous oxide (N2O)
- C.
Methane (CH4)
- D.
Ozone (O3)
Correct Answer
A. Carbon dioxide (CO2)Explanation
Carbon dioxide is the most abundant greenhouse gas emitted by human activities such as burning fossil fuels and deforestation. It traps heat in the atmosphere, contributing significantly to global warming and climate change. While other gases like methane and nitrous oxide also contribute to the greenhouse effect, carbon dioxide is the primary driver due to its long-lasting presence in the atmosphere.Rate this question:

Which of the following is a major contributor to soil erosion?
- A.
Deforestation
- B.
Recycling
- C.
Renewable energy
- D.
Urbanization
Correct Answer
A. DeforestationExplanation
Deforestation, the clearing of forests for agriculture, logging, or urban development, removes vegetation that holds soil in place. Without tree roots and plant cover, soil becomes more susceptible to erosion by wind and water. This leads to loss of fertile topsoil, decreased soil quality, and increased sedimentation in water bodies, impacting ecosystems and agriculture negatively.Rate this question:

- D.
50%
Correct Answer
B. 30%Explanation
Around 30% of air pollution originates from motor vehicles like cars and trucks. Emissions from these vehicles, including nitrogen oxides, particulate matter, and volatile organic compounds, contribute significantly to air pollution, impacting air quality and public health, especially in urban areas with high traffic congestion.Rate this question:
