The greenhouse effect is a process by which atmospheric gases, including carbon dioxide (CO2) help warm the atmosphere and surface of Earth. Most scientists think the greenhouse effect is increasing due to human activities. Which of these human activities has caused the greatest increase in concentrations of atmospheric carbon dioxide (CO2)?

• planting trees

• recycling aluminum

• burning fossil fuels

• using nuclear power

Some scientists have predicted that buildup of greenhouse gases will contribute to the occurrence of more hurricanes. Which is the MOST likely assumption used in making this prediction?

• Acid rainfall will cause a decrease in oceanic surface temperatures

• Increased atmospheric carbon dioxide will cause increased ocean surface temperatures

• Any measurable increase in ocean surface temperatures must be caused by human activities

• Saturation of nitrogen in the atmosphere will cause a wide range of ocean surface temperatures
