Question

which of the following is a way that carbon enters the atmosphere? volcanic activity photosynthesis burial of biomass deposition of sediment

Explanation:

• Volcanic activity releases carbon - containing gases (such as carbon dioxide) into the atmosphere.
• Photosynthesis takes in carbon dioxide from the atmosphere and converts it into organic matter, so it is a process of carbon uptake from the atmosphere, not entry.
• Burial of biomass and deposition of sediment sequester carbon and remove it from the active carbon cycle in the atmosphere.

Answer:

volcanic activity
