Understanding Greenhouse Effect

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.
