Climate Change and Environmental Science

The video reviews Unit 9 of AP Environmental Science, focusing on global change topics like climate change, ozone depletion, and biodiversity. It explains the formation and depletion of stratospheric ozone, the role of greenhouse gases in global warming, and the effects of climate change on habitats and species. The video also covers feedback loops, ocean warming, and acidification, and discusses human impacts on biodiversity, offering conservation strategies.

What is the primary role of stratospheric ozone?

• To cause global warming

• To provide oxygen for breathing

• To absorb dangerous UV radiation

• To trap heat in the atmosphere

Which chemical is primarily responsible for ozone depletion?

• Chlorine from CFCs

• Methane

• Carbon dioxide

• Nitrous oxide

What was the main goal of the Montreal Protocol?

• To reduce carbon emissions

• To phase out the use of CFCs

• To protect endangered species

• To increase the use of fossil fuels

What is the greenhouse effect?

• A phenomenon that only occurs in greenhouses

• A method to reduce global warming

• A natural process that keeps the Earth warm

• A process that cools the Earth's surface

Which protocol aims to reduce greenhouse gas emissions worldwide?

• Paris Agreement

• Kyoto Protocol

• Montreal Protocol

• Geneva Convention

Which greenhouse gas has the highest warming potential?

• Methane

• CFCs

• Carbon dioxide

• Water vapor

What is a positive feedback loop in the context of climate change?

• A loop that cools the Earth's surface

• A loop that reduces global warming

• A loop that encourages further warming

• A loop that has no effect on climate

What is ocean acidification primarily caused by?

• Absorption of carbon dioxide

• Increased levels of methane

• Depletion of ozone

• Rising sea levels

What does the acronym HIPPCO stand for in biodiversity concerns?

• Habitat destruction, Invasive species, Pollution, Population growth, Climate change, Over-fishing

• Habitat destruction, Invasive species, Pollution, Population growth, Conservation, Over-exploitation

• Habitat destruction, Industrialization, Pollution, Population growth, Climate change, Over-exploitation

• Habitat destruction, Invasive species, Pollution, Population growth, Climate change, Over-exploitation

Which act in the United States helps protect endangered species?

• Clean Air Act

• Endangered Species Act

• National Environmental Policy Act

• Safe Drinking Water Act
