Understanding the Greenhouse Effect

What are the primary causes of the greenhouse effect?

• Ozone depletion

• Deforestation

• The primary causes of the greenhouse effect are greenhouse gases like carbon dioxide, methane, and nitrous oxide.

• Solar radiation increase

How does the greenhouse effect contribute to climate change?

• The greenhouse effect cools the Earth by reflecting sunlight away.

• The greenhouse effect has no impact on weather patterns.

• The greenhouse effect only affects local climates, not global temperatures.

• The greenhouse effect contributes to climate change by trapping heat in the atmosphere, leading to global warming.

Name three major greenhouse gases and their sources.

• Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and their sources are fossil fuel combustion, natural gas production, and agricultural activities respectively.

• Ozone (O3) from vehicle emissions

• Water vapor (H2O) from ocean evaporation

• Sulfur dioxide (SO2) from volcanic eruptions

What role does carbon dioxide play in the greenhouse effect?

• Carbon dioxide contributes to the greenhouse effect by trapping heat in the atmosphere.

• Carbon dioxide is a primary source of oxygen in the atmosphere.

• Carbon dioxide cools the atmosphere by reflecting sunlight.

• Carbon dioxide has no impact on the greenhouse effect.

How do human activities exacerbate the greenhouse effect?

• Natural processes are the main cause of the greenhouse effect.

• Human activities reduce greenhouse gas emissions.

• Human activities exacerbate the greenhouse effect by increasing the concentration of greenhouse gases in the atmosphere.

• Human activities have no impact on the greenhouse effect.

What are some natural processes that contribute to the greenhouse effect?

• Photosynthesis

• Ocean currents

• Volcanic eruptions, respiration, decomposition, and wildfires.

• Solar radiation

What strategies can be implemented to mitigate the greenhouse effect?

• Promote deforestation for agriculture

• Implement strategies like reducing fossil fuel use, increasing energy efficiency, transitioning to renewables, enhancing carbon capture, promoting reforestation, and encouraging sustainable agriculture.

• Increase use of coal and oil

• Encourage single-use plastics

How does deforestation impact greenhouse gas levels?

• Deforestation only impacts local wildlife, not greenhouse gases.

• Deforestation increases greenhouse gas levels by reducing CO2 absorption and releasing stored carbon.

• Deforestation has no effect on greenhouse gas levels.

• Deforestation decreases greenhouse gas levels by increasing CO2 absorption.

What is the significance of renewable energy in reducing greenhouse gases?

• Renewable energy is primarily used for heating and has no relevance to electricity generation.

• Renewable energy significantly reduces greenhouse gases by replacing fossil fuels with low or zero-emission energy sources.

• Renewable energy increases greenhouse gas emissions by promoting fossil fuel use.

• Renewable energy has no impact on greenhouse gas levels in the atmosphere.

How can individuals contribute to reducing the greenhouse effect?

• By driving more frequently

• By increasing energy consumption

• By using more plastic products

• Individuals can contribute to reducing the greenhouse effect by adopting sustainable practices.
