Total questions: 15
Worksheet time: 8mins
What is one major cause of global warming?
Greenhouse gas emissions from burning fossil fuels
Increased solar activity
Ocean acidification due to plastic pollution
Deforestation of urban areas
How do human activities contribute to climate change?
Human activities reduce greenhouse gas emissions.
Human activities increase greenhouse gas emissions, leading to climate change.
Human activities have no impact on climate change.
Human activities only affect local weather patterns.
What gas is primarily responsible for the greenhouse effect?
Carbon dioxide (CO2)
Ozone (O3)
Methane (CH4)
Nitrous oxide (N2O)
Name a greenhouse gas that comes from cars.
Methane (CH4)
Nitrous oxide (N2O)
Carbon dioxide (CO2)
Ozone (O3)
How does deforestation affect global warming?
Deforestation decreases carbon dioxide levels in the atmosphere.
Deforestation has no impact on global warming.
Deforestation helps to cool the planet by increasing tree cover.
Deforestation contributes to global warming by increasing carbon dioxide levels in the atmosphere.
What is one effect of climate change on weather patterns?
Decreased rainfall in all regions.
Lower average temperatures globally.
Stable weather patterns year-round.
Increased frequency of extreme weather events.
How do rising temperatures impact polar ice caps?
Melting polar ice caps lead to colder global temperatures.
Rising temperatures cause polar ice caps to melt, leading to sea level rise and climate changes.
Polar ice caps remain unchanged regardless of temperature.
Rising temperatures cause polar ice caps to thicken.
What happens to sea levels as glaciers melt?
Sea levels fluctuate randomly as glaciers melt.
Sea levels rise as glaciers melt.
Sea levels remain unchanged as glaciers melt.
Sea levels decrease as glaciers melt.
How can global warming affect plant life?
Global warming has no effect on plant life whatsoever.
Global warming increases plant growth by providing more sunlight.
Global warming leads to more rainfall, benefiting all plant species.
Global warming can negatively impact plant life by altering growth conditions, disrupting ecosystems, and favoring invasive species.
What is the role of carbon dioxide in the greenhouse effect?
Carbon dioxide has no impact on the greenhouse effect.
Carbon dioxide is a primary source of oxygen in the atmosphere.
Carbon dioxide cools the atmosphere by reflecting sunlight.
Carbon dioxide contributes to the greenhouse effect by trapping heat in the atmosphere.
How does global warming impact animal habitats?
Global warming disrupts animal habitats by altering climate conditions, leading to habitat loss and forcing species to adapt or migrate.
Global warming only affects plant life, not animal habitats.
Animal habitats remain unchanged despite global warming effects.
Global warming increases animal populations by providing more resources.
What is one way that climate change can affect food supply?
Climate change has no impact on agricultural practices.
Increased rainfall can lead to better crop growth.
Altered weather patterns can reduce crop yields.
Higher temperatures always improve food quality.
How do greenhouse gases trap heat in the atmosphere?
Greenhouse gases trap heat by absorbing visible light and preventing it from reaching the surface.
Greenhouse gases trap heat by absorbing infrared radiation emitted from the Earth's surface and re-emitting it, keeping the atmosphere warm.
Greenhouse gases cool the atmosphere by reflecting sunlight away from the Earth.
Greenhouse gases create a barrier that blocks all forms of radiation from escaping the atmosphere.
What is the impact of global warming on ocean temperatures?
Global warming increases ocean temperatures, impacting marine ecosystems and weather patterns.
Global warming decreases ocean temperatures, benefiting marine life.
Ocean temperatures remain unchanged despite global warming.
Global warming only affects freshwater bodies, not oceans.
Why is it important to reduce greenhouse gas emissions?
To promote the use of fossil fuels for energy.
It is important to reduce greenhouse gas emissions to combat climate change and protect the environment.
To increase industrial productivity and economic growth.
To enhance the quality of urban living without concern for the environment.
