What are greenhouse gases?

Back

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

What is the primary source of increased atmospheric carbon dioxide since 1960?

Back

Human activities, particularly the burning of fossil fuels, have led to increased atmospheric carbon dioxide levels.

Front

Which of the following is a natural source of greenhouse gases?

Back

Volcanic eruptions.

Front

What is methane?

Back

Methane (CH4) is a potent greenhouse gas that is released during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices.

Front

What role do aerosols play in climate change?

Back

Aerosols can cool the atmosphere by reflecting sunlight away from the Earth, but they can also contribute to warming by affecting cloud formation.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping back into space, thus warming the planet.

Front

What human activities contribute to climate change?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes contribute to the increase of greenhouse gases in the atmosphere.
