GLOBAL WARMING

What contributes to rising sea levels?

• Melting ice caps and water contraction
• Melting ice caps and decreased evaporation
• Melting ice caps and water expansion
• Melting ice caps and increased rainfall

What happens when fuels are burned?

• They release greenhouse gases
• They have no effect on climate change
• They decrease global temperatures
• They absorb greenhouse gases

What are greenhouse gases?

• Gases that cool the Earth
• Gases that protect the ozone layer
• Gases that warm the Earth
• Gases that cause acid rain

What is a major cause of climate change?

• Burning fuels
• Solar radiation
• Deforestation
• Volcanic activity

What are the consequences of flooding and erosion on buildings and infrastructure?

• Decreased maintenance costs
• Damage and destruction
• Improved structural integrity
• Increased property value

What is the Earth's source of warmth?

• The Earth's core
• The Earth's atmosphere
• The Moon's radiation
• The Sun's solar radiation

How do greenhouse gases help to keep Earth warm?

• By creating a protective layer around the Earth
• By increasing the ozone layer
• By reflecting heat back into space
• By absorbing heat from the Sun

How do rising sea levels impact coastal areas?

• Improved fishing opportunities
• Increased tourism
• Flooding and erosion
• Enhanced biodiversity

How does the Earth's atmosphere work to keep warmth inside?

• By reflecting back infrared heat waves
• By absorbing solar radiation
• By preventing greenhouse gases from entering
• By reflecting back ultraviolet rays

What is the impact of deforestation on carbon dioxide levels in the atmosphere?

• Deforestation has no impact on carbon dioxide levels
• Deforestation reduces the amount of carbon dioxide in the atmosphere
• Deforestation increases the concentration of carbon dioxide in the atmosphere
• Deforestation releases carbon dioxide into the atmosphere
