Climate Change Quiz

What is the sum of anthropogenic climate change and natural climate change referred to as?

• Global warming

• Total climate change

• Environmental degradation

• Atmospheric instability

How do aerosols emitted by volcanoes affect Earth's temperature?

• They absorb sunlight, increasing Earth's temperature.

• They reflect sunlight back into space, cooling Earth.

• They trap heat in the atmosphere, warming Earth.

• They have no impact on Earth's temperature.

How do tree rings appear during cold and dry years?

• Thinner.

• Wider.

• Darker.

• Lighter.

What is the significance of oxygen in forming the ozone layer?

• It traps heat and warms the planet.

• It protects us from UV radiation.

• It generates ice sheets by cooling temperatures.

• It displaces methane to increase global temperatures.

Which of the following is NOT a source of increased carbon dioxide levels caused by human activities?

• Pollution

• Releasing CO₂ reserves from rocks and soil

• Deforestation

• Natural volcanic eruptions

How does climate change affect small areas like the tropical Pacific?

• It causes extreme heat waves.

• Aerosol release leads to cooling in the area.

• It increases the frequency of hurricanes.

• It leads to desertification.

What has been the trend in atmospheric carbon dioxide levels over the last 400,000 years before the 1950s?

• Carbon dioxide levels consistently stayed above 300 ppm.

• Carbon dioxide levels fluctuated but stayed below 300 ppm.

• Carbon dioxide levels were stable at 500 ppm.

• Carbon dioxide levels decreased steadily over time.

How do Milankovitch cycles affect climate change?

• They cause short-term weather changes.

• They influence Earth's long-term climate patterns by altering its orbit and axial tilt.

• They are responsible for volcanic eruptions.

• They have no impact on Earth's climate.

What is coral bleaching, and what causes it?

• Coral bleaching occurs when coral grows too quickly due to warm water.

• Coral bleaching happens when coral and algae lose their symbiotic relationship due to water pollution and stress.

• Coral bleaching is caused by the migration of coral to higher latitudes.

• Coral bleaching occurs when coral becomes overpopulated with algae.

What happens to CFCs when they drift upward to the stratosphere?

• They are broken up by UV radiation.

• They release oxygen atoms.

• They combine with ozone molecules.

• They remain unchanged.
