• 1.

The global sea level has rose 20.7 inches since the last century. Fact or Fiction?

• A.

Fact

• B.

Fiction

B. Fiction
Explanation
The global sea level only rose 6.7 inches.

Rate this question:

• 2.

The average value of CO2 release is 1.4 billion pounds per day. Fact or Fiction?

• A.

Fact

• B.

Fiction

A. Fact
Explanation
The given answer "Fact" is correct because it states that the average value of CO2 release is 1.4 billion pounds per day. This implies that there is data or evidence supporting this claim, indicating that CO2 is indeed released at this rate on a daily basis.

Australia releases more carbon dioxide than any other country, though it is home to just five percent of the world's population. If everyone in the world lived the way people do in the U.S., it would take five Earths to provide enough resources for everyone! Fact or Fiction?

• A.

Fact

• B.

Fiction

B. Fiction
Explanation
Some of you may got this question incorrect. America releases more carbon dioxide than any other country and is home for just 5% of the world. You would also need to use your general knowledge to answer this question correctly.

In general, the greenhouse effect is a good thing. Without greenhouse gases, the temperature on Earth would be too cold to support life. With too many, it would heat up beyond survivable levels. Earth is sometimes called the Goldilocks Planet because it is "just right." Fact or Fiction?

• A.

Fact

• B.

Fiction

A. Fact
Explanation
The statement is true because it accurately describes the greenhouse effect and its importance for supporting life on Earth. The greenhouse effect is a natural process where certain gases in the atmosphere trap heat from the sun, warming the planet. Without this effect, the Earth's temperature would be too cold for life to exist. However, an excessive amount of greenhouse gases can lead to global warming and negative impacts on the environment. Therefore, the statement that the greenhouse effect is a good thing is correct.

• 5.

Brazil has the highest annual rate of deforestation today. Fact or Fiction?

• A.

Fact

• B.

Fiction

A. Fact
Explanation
Brazil has the highest annual rate of deforestation today. This statement is true because Brazil has been experiencing high levels of deforestation due to activities such as logging, agriculture, and urbanization. The Amazon rainforest, which is located in Brazil, has been particularly affected by deforestation. This has significant environmental consequences, including the loss of biodiversity, disruption of ecosystems, and contribution to climate change. Therefore, it is accurate to say that Brazil currently has the highest annual rate of deforestation.

Rate this question:

• 6.

Which of these cause the greenhouse effect?

• A.

Excess of nitrogen in the atmosphere

• B.

Excess of carbon dioxide in the atmosphere

• C.

Heat from cooking fires of ever-increasing population

• D.

None of the above

B. Excess of carbon dioxide in the atmosphere
Explanation
The greenhouse effect is caused by an excess of carbon dioxide in the atmosphere. Carbon dioxide is a greenhouse gas that traps heat from the sun in the Earth's atmosphere, leading to a rise in global temperatures. This phenomenon has significant impacts on climate change and can result in various environmental and ecological consequences.

Rate this question:

• 7.

Which of these is NOT an expected effect of climate change?

• A.

Sea levels rising

• B.

Flooding in coastal cities

• C.

Expanding glaciers

• D.

Extreme weather

C. Expanding glaciers
Explanation
Expanding glaciers is not an expected effect of climate change. Climate change is causing global temperatures to rise, resulting in the melting of glaciers and ice caps. This leads to a decrease in the size and coverage of glaciers, rather than expansion.

Rate this question:

• 8.

What can you do about climate change?

• A.

Drive your car less and use public transport

• B.

Turn off the lights when not in need

• C.

All of the above the above

C. All of the above the above
Explanation
The correct answer is "All of the above." This means that both driving your car less and using public transport, as well as turning off the lights when not in need, are actions that can be taken to address climate change. By reducing car usage and using public transport, we can decrease carbon emissions from vehicles. Similarly, by turning off lights when not in use, we can conserve energy and reduce greenhouse gas emissions. Therefore, all of these actions contribute to mitigating climate change.

Rate this question:

• 9.

What percentage of heat from global warming has the ocean absorbed in the last forty years?

• A.

11%

• B.

1%

• C.

35%

• D.

84%

D. 84%
Explanation
In the last forty years, the ocean has absorbed 84% of the heat from global warming. This means that a significant amount of the heat generated by global warming is being absorbed by the ocean, which has important implications for the Earth's climate system. The ocean acts as a heat sink, helping to regulate the overall temperature of the planet. The high percentage of heat absorption by the ocean highlights the important role it plays in mitigating the effects of global warming.

Rate this question:

• 10.

El Nino is a result of global warming. True or false?

• A.

True

• B.

False

B. False
Explanation
The given answer is false because El Nino is not a direct result of global warming. El Nino is a natural climate pattern that occurs in the Pacific Ocean, characterized by warmer than usual sea surface temperatures. It is caused by changes in ocean currents and atmospheric pressure, not directly related to global warming. While global warming can potentially influence the intensity and frequency of El Nino events, it is not the sole cause of El Nino.
