Question

while the fast processes of the carbon cycle are biological and mainly involve the biosphere, the slow processes of the carbon cycle are primarily geological and involve interactions between the geosphere, hydrosphere, and atmosphere, with limited biosphere involvement. each year, up to 100 million metric tons of carbon moves between rocks, soils, bodies of water, and the air via chemical reactions and geological activity. this is less than 1% of the amount of carbon that moves through the biological processes of the carbon cycle annually. classify each carbon cycle process as fast or slow. decomposition cellular respiration formation of limestone consumption formation of coal volcanic activity photosynthesis weathering of rocks fast process slow process the carbon - rich limestone cliffs in ha long bay, vietnam, formed over millions of years.

Explanation:

To classify, we use the given info: Fast processes are biological (involve biosphere), slow are geological (involve geosphere, hydrosphere, atmosphere, limited biosphere).

• Fast (biological): Decomposition (breaks down organic matter, biosphere), Cellular Respiration (organisms release CO₂, biosphere), Consumption (organisms eat, biosphere), Photosynthesis (plants fix CO₂, biosphere).
• Slow (geological): Formation of limestone (geological, takes millions of years), Formation of coal (geological, long - term), Volcanic activity (geological, involves geosphere), Weathering of rocks (geological, long - term).

Answer:

Fast process: decomposition, cellular respiration, consumption, photosynthesis
Slow process: formation of limestone, formation of coal, volcanic activity, weathering of rocks
