Question

the carbon cycle

1. what are the major reservoirs of the carbon cycle?
2. what are the limitations of the carbon cycle?
3. how can humans positively impact the carbon cycle?
4. how do humans negatively impact the carbon cycle?

Explanation:

1. The major reservoirs of the carbon - cycle include the atmosphere (as CO₂), the oceans (dissolved carbon compounds), soil (organic carbon), and fossil fuels (coal, oil, gas).
2. Limitations of the carbon cycle are not well - defined in a traditional sense. However, human activities can overwhelm the natural cycle's capacity to balance carbon, such as rapid deforestation reducing carbon sequestration.
3. Humans can positively impact the carbon cycle by reforestation (trees absorb CO₂), using renewable energy sources (reducing fossil - fuel emissions), and improving soil management (increasing carbon storage in soil).
4. Humans negatively impact the carbon cycle through activities like burning fossil fuels (releasing large amounts of CO₂), deforestation (reducing carbon sinks), and industrial processes (emitting greenhouse gases).

Answer:

1. Atmosphere, oceans, soil, fossil fuels.
2. Human activities can overwhelm its balancing capacity.
3. Reforestation, using renewable energy, improving soil management.
4. Burning fossil fuels, deforestation, industrial processes.
