Environmental Science Quiz

What is glacial retreat?

• The process of a glacier disappearing completely over time due to erosion.

• The process of a glacier staying the same size over time.

• The process of a glacier shrinking or receding over time due to melting and sublimation of ice.

• The process of a glacier growing or expanding over time due to accumulation of ice.

What are greenhouse gas emissions?

• Gases that deplete the ozone layer

• Gases that have no effect on the Earth's atmosphere

• Gases that cool the Earth's atmosphere

• Gases that trap heat in the Earth's atmosphere

Define climate change.

• Short-term changes in temperature and weather patterns caused by natural factors.

• Changes in the Earth's orbit and axis that result in variations in climate.

• Fluctuations in temperature and weather patterns caused by random events.

• Long-term shifts in temperature and weather patterns caused by human activities.

Explain the albedo effect.

• The albedo effect is the ability of a surface to absorb sunlight.

• The albedo effect is the ability of a surface to generate sunlight.

• The albedo effect is the ability of a surface to emit sunlight.

• The albedo effect is the ability of a surface to reflect sunlight.

What is carbon sequestration?

• The process of using carbon dioxide to generate renewable energy.

• The process of capturing and storing carbon dioxide from the atmosphere to mitigate climate change.

• The process of converting carbon dioxide into a solid form for storage.

• The process of releasing carbon dioxide into the atmosphere to accelerate climate change.

How does glacial melt contribute to climate change?

• Glacial melt does not contribute to climate change.

• Glacial melt contributes to climate change by releasing greenhouse gases.

• Glacial melt contributes to climate change by increasing cloud cover.

• Glacial melt contributes to climate change by increasing sea levels and reducing the Earth's albedo.

List some examples of greenhouse gases.

• water vapor, ozone, sulfur hexafluoride, chlorofluorocarbons

• carbon dioxide, methane, nitrous oxide, fluorinated gases

• oxygen, nitrogen, argon, helium

• carbon monoxide, nitrogen dioxide, sulfur dioxide, volatile organic compounds

What are the impacts of climate change on ecosystems?

• Climate change has no impact on ecosystems.

• Climate change only affects temperature and precipitation patterns.

• Climate change only affects biodiversity.

• Climate change has various impacts on ecosystems, including changes in temperature and precipitation patterns, shifts in species distribution and abundance, altered food webs, increased frequency and intensity of extreme weather events, and loss of biodiversity.

How does the albedo effect affect global warming?

• The albedo effect affects global warming by trapping heat in the atmosphere.

• The albedo effect affects global warming by increasing the concentration of greenhouse gases.

• The albedo effect affects global warming by causing the Earth's temperature to decrease.

• The albedo effect affects global warming by reflecting sunlight back into space.

What are some methods of carbon sequestration?

• Ocean acidification, deforestation, air pollution

• Renewable energy, recycling, reducing waste

• Afforestation, reforestation, carbon capture and storage (CCS), enhancing soil carbon storage

• Deforestation, carbon emissions, burning fossil fuels
