Greenhouse Effect and Global Warming starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Greenhouse Effect and Global Warming.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe the role of oceans in regulating atmospheric carbon dioxide levels.
Describe two consequences of global warming on the environment.
Explain the difference between weather and climate in the context of global warming.
Explain the process of the greenhouse effect in your own words.
Explain why increasing atmospheric concentrations of greenhouse gases lead to higher global temperatures.
A city has an average temperature increase of 2°C over 50 years. Is this change more likely due to weather or climate change?
A factory emits 1,000 kg of methane (CH4) and 10,000 kg of carbon dioxide (CO2) annually. Given that the global warming potential (GWP) of methane over 100 years is 25, calculate the total CO2-equivalent emissions from this factory per year.
A scientist measures the outgoing longwave radiation from Earth's surface and finds it is lower than expected. What could be a possible explanation for this observation in terms of the greenhouse effect?
Which gas has the highest global warming potential (GWP) over a 100-year period?
(1) Carbon dioxide
(2) Methane
(3) Nitrous oxide
(4) Chlorofluorocarbons (CFCs)
Which of the following best explains why polar regions are more affected by global warming?
(1) They receive more sunlight
(2) Ice and snow reflect less sunlight as they melt, causing more absorption of heat
(3) They have more greenhouse gases
(4) They are closer to the equator
Which of the following gases is considered the most significant contributor to the greenhouse effect on Earth?
(1) Oxygen
(2) Nitrogen
(3) Carbon dioxide
(4) Argon
Which of the following human activities is a major source of methane emissions?
(1) Burning coal
(2) Rice cultivation
(3) Using solar panels
(4) Wind energy production
