Chapter 18: Global Climate Change

What are greenhouse gas emissions?

• Gases that have no effect on the atmosphere

• Gases that trap heat in the atmosphere

• Gases that cool the atmosphere

• Gases that repel heat from the atmosphere

How does climate change affect biodiversity?

• Climate change can lead to habitat loss, reducing biodiversity

• Extreme weather events have a positive effect on biodiversity

• Biodiversity increases with climate change

• Climate change has no impact on biodiversity

What is ocean acidification?

• Ocean acidification is the process of the ocean pH decreasing due to higher nitrogen content

• Ocean acidification is the process of the ocean becoming less salty due to excessive rainfall.

• Ocean acidification is the process of the ocean pH decreasing due to higher carbon dioxide content

• Ocean acidification is the process of the ocean pH increasing due to increased calcium carbonate

Which greenhouse gas is the most significant contributor to climate change?

• Oxygen (O2)

• Nitrogen (N2)

• Methane (CH4)

• Carbon dioxide (CO2)

How do greenhouse gas emissions contribute to the greenhouse effect?

• Greenhouse gas emissions create a protective layer in the atmosphere

• Greenhouse gas emissions trap heat in the Earth's atmosphere

• Greenhouse gas emissions cool down the Earth's atmosphere

• Greenhouse gas emissions have no impact on the greenhouse effect

What is the impact of deforestation on climate change?

• Deforestation has no impact on climate change

• Deforestation reduces the impact of climate change

• Deforestation increases the impact of climate change

• Deforestation reverses climate change

What is the role of renewable energy in mitigating climate change?

• Renewable energy increases greenhouse gas emissions

• Renewable energy has no impact on greenhouse gas emissions

• Renewable energy reduces greenhouse gas emissions

• Renewable energy has an unpredictable impact on greenhouse gas emissions

What is the effect of climate change on sea levels?

• Climate change causes sea levels to rise

• Climate change causes sea levels to fall

• Climate change has no impact on sea levels

• Climate change causes sea levels to remain constant

Which human activity contributes the MOST carbon dioxide to the atmosphere?

• Fishing
• Breathing
• Burning Fossil Fuels
• Farming

What results from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills?

• Carbon Dioxide

• Methane

• Water Vapor

• Fluorinated Gases

• Nitrous Oxide
