Front

What is carbon dioxide?

Back

A colorless, odorless gas produced by burning fossil fuels and organic matter, and a key greenhouse gas in Earth's atmosphere.

Front

What is the greenhouse effect?

Back

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

Front

What are fossil fuels?

Back

Natural substances like coal, oil, and natural gas formed from the remains of ancient plants and animals, used as energy sources.

Front

What is combustion?

Back

A chemical reaction that occurs when a substance reacts with oxygen, producing heat and light, often resulting in the release of carbon dioxide.

Front

What is methane?

Back

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 is deforestation?

Back

The clearing or thinning of forests by humans, which can lead to increased carbon dioxide levels in the atmosphere.

Front

What is the role of the ozone layer?

Back

A region of Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet radiation, protecting living organisms.

Front

What is global warming?

Back

The long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels.

Front

What is energy balance in Earth's climate system?

Back

The relationship between the energy Earth receives from the Sun and the energy it radiates back into space.

Front

What is the impact of increased carbon dioxide on climate?

Back

Higher levels of carbon dioxide enhance the greenhouse effect, leading to increased global temperatures.
