Carbon Cycle Review: Standard

Front

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.

Front

What is combustion in the context of the carbon cycle?

Back

Combustion is the process of burning fossil fuels or biomass, which releases carbon dioxide into the atmosphere.

Front

True or False: Carbon dioxide is easily dissolved in water.

Back

True

Front

Which process does NOT add carbon to the atmosphere: volcanic eruptions, respiration, weathering of limestone, or subduction?

Back

Subduction does NOT add carbon to the atmosphere.

Front

Where is carbon NOT stored in the carbon cycle: fossil fuels, water, atmosphere, or sunlight?

Back

Sunlight is NOT a storage location for carbon.

Front

True or False: Deforestation can hurt the carbon cycle.

Back

True

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 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

How do oceans contribute to the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and store it in water, which can be used by marine life.

Front

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels store carbon that was once part of living organisms, and burning them releases carbon dioxide back into the atmosphere.
