the carbon cycle: biosphere processes and interactions (97)

Explanation:

1. For "Carbon moves from the geosphere to the atmosphere, mostly due to human activities" - Fossil fuel combustion is when humans burn fossil fuels (from geosphere) releasing CO₂ to atmosphere. So match with fossil fuel combustion.
2. For "Carbon moves from the biosphere to the geosphere" - Fossil fuel formation involves dead organisms (biosphere) being buried and transformed into fossil fuels (geosphere). So match with fossil fuel formation.
3. For "Carbon moves from the geosphere to the atmosphere due to natural events" - Volcanic activity is a natural event where volcanoes (geosphere) release carbon (as CO₂) to atmosphere. So match with volcanic activity.

Answer:

• fossil fuel combustion: Carbon moves from the geosphere to the atmosphere, mostly due to human activities.
• fossil fuel formation: Carbon moves from the biosphere to the geosphere.
• volcanic activity: Carbon moves from the geosphere to the atmosphere due to natural events.
