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
A city has an average temperature increase of 2°C over 50 years. Is this change more likely due to weather or climate change?
Calculate the increase in atmospheric CO2 concentration if it rises from 350 ppm to 400 ppm over 20 years. What is the total increase in ppm?
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.
Explain why methane is considered a more potent greenhouse gas than carbon dioxide, even though it is present in lower concentrations.
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?
Describe the chemical process by which nitrous oxide (N2O) is produced in agricultural soils and explain its significance as a greenhouse gas.
Explain how the concept of radiative forcing is used to compare the impact of different greenhouse gases on global warming.
Explain why the absorption spectra of greenhouse gases are important in understanding their effect on Earth's energy balance.
