Carbon Cycle Practice

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of dead organic matter (biomass) that have been pressurized over time into solid, liquid, or gaseous states. Examples include coal, oil, and natural gas.

Front

What is decomposition in the carbon cycle?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning carbon to the atmosphere and soil.

Front

What is respiration in the carbon cycle?

Back

Respiration is the process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide as a byproduct.

Front

What is photosynthesis?

Back

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

Front

What role do plants play in the carbon cycle?

Back

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

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate, supporting life, and maintaining the balance of carbon in the atmosphere, oceans, and terrestrial ecosystems.

Front

What is combustion?

Back

Combustion is a chemical process in which a substance reacts with oxygen to produce heat and light, often resulting in the release of carbon dioxide.

Front

What is the role of oceans in the carbon cycle?

Back

Oceans act as a major carbon sink, absorbing carbon dioxide from the atmosphere and storing it in water and marine organisms.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide, in the atmosphere.

Front

How do human activities impact the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle.
