Question

sort the processes based on whether they store or release carbon.
volcanic activity fossil fuel combustion
fossil fuel formation limestone formation
store carbon
release carbon

Explanation:

Step1: Analyze each process

• Fossil fuel formation: Organic matter is buried and transformed over time, storing carbon.
• Limestone formation: Involves carbon incorporation into rock, storing carbon.
• Volcanic activity: Releases carbon (e.g., CO₂) from Earth's interior.
• Fossil fuel combustion: Burns fuels, releasing carbon as CO₂.

Step2: Categorize

• Store carbon: fossil fuel formation, limestone formation.
• Release carbon: volcanic activity, fossil fuel combustion.

Answer:

Store carbon: fossil fuel formation, limestone formation
Release carbon: volcanic activity, fossil fuel combustion
