Unit 6 Greenhouse Effect Checkpoint

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What are greenhouse gases (GHGs)?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How do greenhouse gases affect global temperature?

Back

As the concentration of greenhouse gases increases, the average global temperature rises due to more heat being trapped in the atmosphere.

Front

What happens to infrared radiation that is not absorbed by greenhouse gases?

Back

Infrared radiation that is not absorbed by greenhouse gases is reflected back to space.

Front

Why does a car feel warmer inside after sitting in the sun?

Back

A car feels warmer inside because sunlight enters through the windows and heats the interior, while the heat is trapped inside, preventing it from escaping.

Front

What is the role of carbon dioxide in global warming?

Back

Increased carbon dioxide levels contribute to global warming by trapping more heat in the atmosphere.

Front

What is the significance of the greenhouse effect for life on Earth?

Back

The greenhouse effect is crucial for maintaining a temperature that is comfortable for most living organisms, allowing ecosystems to thrive.

Front

What are some examples of human activities that increase greenhouse gas emissions?

Back

Examples include burning fossil fuels for energy, deforestation, and industrial processes.

Front

What is the relationship between greenhouse gas emissions and climate change?

Back

Increased greenhouse gas emissions lead to climate change by causing global temperatures to rise, resulting in altered weather patterns and environmental impacts.

Front

What is the difference between natural and anthropogenic greenhouse gases?

Back

Natural greenhouse gases are produced by natural processes (e.g., volcanic eruptions), while anthropogenic greenhouse gases are emitted through human activities.
