Understanding the Carbon Cycle

What are the two main processes involved in the carbon cycle?

• Uplift and Deposition

• Decomposition and Erosion

• Storing and Moving Carbon

• Photosynthesis and Respiration

Where is the most carbon dioxide stored?

• In plants

• In fossil fuels

• In the ocean

• In the atmosphere

Which process allows plants to take carbon dioxide from the atmosphere?

• Decomposition

• Erosion

• Respiration

• Photosynthesis

What happens during respiration in the carbon cycle?

• Carbon is moved by erosion

• Carbon compounds are broken down to release energy

• Carbon dioxide is absorbed by plants

• Carbon is stored in fossil fuels

Which process involves the breakdown of dead organisms, returning carbon to the ground?

• Respiration

• Uplift

• Decomposition

• Photosynthesis

How does human activity primarily move carbon?

• By reducing erosion

• By planting more trees

• By burning fossil fuels

• By increasing oceanic algae

What is the role of volcanic activity in the carbon cycle?

• It stores carbon in the atmosphere

• It releases carbon dioxide into the atmosphere

• It absorbs carbon from the ocean

• It prevents erosion

What is the effect of erosion on carbon movement?

• It releases carbon into the atmosphere

• It prevents carbon from moving

• It stores carbon in the soil

• It moves carbon from land to water sources

How does carbon dioxide move between the atmosphere and the ocean?

• Through volcanic activity

• By dissolving and evaporating

• By human intervention

• Through photosynthesis

What is a key takeaway about the carbon cycle?

• Carbon is both stored and moved through various processes

• Carbon is not affected by geological processes

• Carbon is only moved by human activities

• Carbon is only stored in the atmosphere
