What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the Earth's atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

Where is carbon NOT stored in the carbon cycle?

Back

Sunlight

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat by absorbing the sun's radiation. They include carbon dioxide, methane, and water vapor.

Front

How do greenhouse gases affect global warming?

Back

Greenhouse gases contribute to global warming by trapping heat in the atmosphere, leading to an increase in Earth's average temperature.

Front

Is all carbon in existence recycled in the carbon cycle?

Back

True

Front

What role does photosynthesis play in the carbon cycle?

Back

Photosynthesis takes carbon dioxide from the atmosphere and water from the soil to produce glucose and oxygen, effectively removing carbon from the atmosphere.

Front

What happens to carbon during respiration?

Back

During respiration, living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

How can global warming cause sea levels to rise?

Back

Global warming can cause sea levels to rise by melting glaciers and ice caps, which adds more water to the oceans.

Front

What is the main source of carbon dioxide emissions?

Back

The main sources of carbon dioxide emissions are the burning of fossil fuels, deforestation, and industrial processes.

Front

What is the significance of carbon sinks?

Back

Carbon sinks are natural systems, like forests and oceans, that absorb more carbon dioxide than they release, helping to mitigate climate change.
