CLIMATE CHANGE REVIEW

What is the main cause of current climate change?

• Natural fluctuations in the Earth's climate
• Human activities increasing greenhouse gas emissions.
• Increased solar radiation
• Volcanic eruptions releasing carbon dioxide

Which gas is the most responsible for the greenhouse effect?

• Ozone (O3)
• Nitrous oxide (N2O)
• Carbon dioxide (CO2)
• Methane (CH4)

What can rising global temperatures lead to?

• Decreased agricultural productivity
• Lower global temperatures
• Increased biodiversity
• Increased extreme weather events, rising sea levels, and ecosystem disruptions.

Which of the following is not a greenhouse gas?

• Methane
• Carbon Dioxide
• Oxygen
• Nitrous Oxide

Which sector is the largest emitter of greenhouse gases globally?

• Agriculture sector
• Transportation sector
• Industrial sector
• Energy sector

Why is deforestation bad for the climate?

• Deforestation helps to reduce carbon dioxide levels.
• Deforestation has no impact on the climate.
• Deforestation increases oxygen levels in the atmosphere.
• Deforestation is bad for the climate because it increases carbon dioxide levels, contributing to global warming.

Which of the following is not a major component of the Earth's climate system?

• Oceans
• Atmosphere
• Biosphere
• None of the above (if options are provided) or a specific option that is unrelated to climate components.

What happens when one part of the climate system changes?

• The climate system remains unchanged.
• Changes are temporary and have no lasting effects.
• Only the local area is affected.
• A change in one part of the climate system can affect the entire system, leading to broader environmental impacts.

What is the greenhouse effect's role in the climate system?

• The greenhouse effect cools the Earth by reflecting sunlight away.
• The greenhouse effect has no impact on weather patterns.
• The greenhouse effect regulates Earth's temperature, enabling life by trapping heat in the atmosphere.
• The greenhouse effect is solely responsible for ozone depletion.

What is one way individuals can help reduce climate change?

• Use public transportation or alternative modes of travel.
• Using more plastic products for convenience.
• Planting more trees in urban areas only.
