The Carbon Cycle

Front

What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon moves through the Earth's systems, including the atmosphere, oceans, soil, and living organisms.

Front

What human activity increases carbon levels in the atmosphere?

Back

Deforestation increases carbon levels in the atmosphere by reducing the number of trees that can absorb carbon dioxide.

Front

Which of the following is NOT a natural source of carbon released into the atmosphere?

Back

Burning fossil fuels is NOT a natural source; it is a human activity that increases carbon emissions.

Front

True or False: Climate change has no effect on weather patterns.

Back

False. Climate change significantly affects weather patterns.

Front

What is one effective strategy to stabilize the carbon cycle?

Back

Renewable energy and reforestation are effective strategies to stabilize the carbon cycle.

Front

What role do plants play in the Carbon Cycle?

Back

Plants absorb carbon dioxide during photosynthesis, helping to reduce carbon levels in the atmosphere.

Front

What is a natural source of carbon dioxide?

Back

Volcanic eruptions are a natural source of carbon dioxide released into the atmosphere.

Front

How do animals contribute to the Carbon Cycle?

Back

Animals contribute to the Carbon Cycle through respiration, releasing carbon dioxide back into the atmosphere.

Front

What is the impact of fossil fuel combustion on the Carbon Cycle?

Back

Combustion of fossil fuels releases large amounts of carbon dioxide, disrupting the natural balance of the Carbon Cycle.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert carbon dioxide and sunlight into glucose and oxygen.
