Climate Change and Global Warming Review

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat. They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space, which helps to keep the planet warm.

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

Front

What is ocean acidification?

Back

Ocean acidification is the process by which the ocean becomes more acidic due to increased levels of carbon dioxide (CO2) in the atmosphere, affecting marine life.

Front

What are carbon sinks?

Back

Carbon sinks are natural systems, such as forests and oceans, that absorb more carbon dioxide from the atmosphere than they release.

Front

What is deforestation?

Back

Deforestation is the clearing or thinning of forests by humans, which can lead to increased carbon emissions and loss of biodiversity.

Front

What is the role of photosynthesis in carbon cycling?

Back

Photosynthesis is the process by which plants convert carbon dioxide (CO2) and sunlight into glucose and oxygen, helping to reduce atmospheric CO2 levels.

Front

What is the significance of PPM in environmental science?

Back

PPM stands for parts per million, a unit of measurement used to describe the concentration of substances, such as greenhouse gases, in the atmosphere.

Front

What are natural sources of greenhouse gases?

Back

Natural sources of greenhouse gases include volcanic eruptions, wildfires, and respiration from living organisms.

Front

What human activities contribute to greenhouse gas emissions?

Back

Human activities that contribute to greenhouse gas emissions include burning fossil fuels, industrial processes, and deforestation.
